Anti-vaccine activists endured a cold, rainy day in Washington one recent Friday, to rally against childhood vaccines.

Gabriele Cashman drove for five hours to support the anti-vaccine cause. She and her husband don’t want anyone to force anything on their children when they have them. 

“As parents, it’s our decision whether or not we want to vaccinate,” she said.

Watch: Top Doctors Address Vaccine Safety

The anti-vaccine movement has gained so much momentum that doctors like Peter Hotez are alarmed. Hotez works on vaccines at Baylor College of Medicine in Houston, Texas. 

“We now, in the state of Texas, have 50,000 kids whose parents are opting them out of getting vaccinated,” he said.

Hotez said these children generally live in communities near each other. He is concerned that only an outbreak of measles will convince these parents that vaccines save lives and prevent disability.

The activists don’t believe the science. Instead, they believe vaccines can cause anything from autism to severe allergies.

But Dr. Anthony Fauci at the National Institutes of Health says while children can have an adverse reaction, it’s so rare, that it’s unmeasurable. Fauci heads the National Institute of Allergy and Infectious Diseases and oversees the development of vaccines.

Side effects that children may have are usually minor, according to Dr. Linda Fu, a pediatrician at Children’s National Medical Center in Washington. 

“The most common side effects to any of these vaccines are pain at the injection site and fever for 24 to 48 hours,” Fu said.

Still, anti-vaccine activists, like Irine Pi, who helped organize the protest in Washington, are convinced harmful ingredients are added to vaccines. The preservative thimerosal was removed from vaccines in the U.S. by 2003, to help alleviate parents’ concerns that it caused autism. Numerous studies in the U.S. and elsewhere show it has no negative effect on children. But Pi is adamant that harmful ingredients are in vaccines routinely given to children.

“Now it’s aluminum that has been added. Add to that formaldehyde, polysorbate, and add to that significant human aborted fetal cell lines, bovine cells, pigs, sheep, monkey, dog. These cells are not meant to be injected into the human body,” Pi said.

Again, the science says otherwise. Fu has a specialty in immunizations. She told VOA, “The vaccines that the children are getting today are more pure and are very safe and effective.”

They are so effective that Dr. Flavia Bustreo at the World Health Organization says young people have no memory of the diseases they prevent.

“Currently, if you speak with any young mother or young father in Italy, where I come from, they don’t know diphtheria. They’ve never seen it. They don’t know that you can lose your child from diphtheria,” she said.

The World Health Organization has an online site to help parents find reliable information on vaccine safety. The CDC does the same.

Hotez wants the U.S. government to launch a campaign to persuade parents to vaccinate their children, but Fauci disagrees.

“I think that there will be a certain number of people, a certain percentage of people, who no matter what you say to convince them with evidence, they’re not going to be convinced, but I think the approach towards people who are anti-vaccinating is to respect their opinion and don’t denigrate them and don’t criticize them, but try to explain to them on the basis of solid evidence why the risk/benefit of vaccines clearly, clearly favors very, very heavily towards vaccinating your children,” Fauci said.

Hotez is now writing books for parents about vaccines. He says scientists have to get away from their laboratories and talk to people about vaccines.

Otherwise, he says, children will suffer and die from diseases that can be prevented.

California lawmakers pushed forward Wednesday with a proposal that would substantially remake the health care system of the nation’s most populous state by replacing insurance companies with government-funded health care for everyone.

The idea known as single-payer health care has long been popular on the left and is getting a new look in California as President Donald Trump looks to replace former President Barack Obama’s health care law.

The proposal, promoted by the state’s powerful nursing union and two Democratic senators, is a longshot. But supporters hope the time is right to persuade lawmakers in California, where Democrats like to push the boundaries of liberal public policy and are eager to stand up to the Republican president.

“It is time to say once and for all that health care is a right, not a privilege for those who can afford it,” said Democratic Sen. Ricardo Lara of Bell Gardens, who wrote the bill along with Democratic Sen. Toni Atkins of San Diego.

Hundreds of nurses clad in red rallied in support of the measure and marched to the state Capitol in Sacramento, packing the hallways before a Senate Health Committee hearing. They were joined by Democratic activists and supporters of Vermont Senator Bernie Sanders, who advocated single-payer health care in his unsuccessful presidential campaign and has introduced federal legislation.

Democrats on the panel voted to advance the measure.

No out-of-pocket costs

The measure would guarantee health coverage with no out-of-pocket costs for all California residents, including people living in the country illegally.

Private insurers would be barred from covering the same services, essentially eliminating them from the marketplace. Instead, a new state agency would set prices and contract with health care providers such as doctors and hospitals and pay the bills for everyone. 

However, an essential question is unanswered: Where will the money come from? California health care expenditures last year totaled more than $367 billion, according to the Center for Health Policy Research at University of California, Los Angeles.

The measure envisions using all public money spent on health care — from Medicare, Medicaid, federal public health funds and “Obamacare” subsidies. But it also would require significant tax increases on businesses, residents or both to replace billions of dollars in health care spending by employers and individuals while generating enough money to cover people who are currently uninsured.

The California Nurses Association commissioned a study of the costs and potential funding methods that will be ready before the measure goes before the next committee later this year, spokesman Chuck Idelson said.

Opposition

Employers, business groups and health plans have mobilized in opposition, warning that the measure would require massive tax increases and force patients into lengthy waits to see a doctor.

They say the state should stay focused on implementing Obama’s health care law, which is credited with significantly reducing the ranks of California’s uninsured.

“California can’t afford a single-payer health care system,” said Charles Bacchi, president and CEO of the California Association of Health Plans. “It’s going to reduce the quality of care. We think it will restrict access to care, and it will be incredibly disruptive to all the Californians who currently get health care coverage through their employer.”

The idea faces significant hurdles.

The bill, SB562, would affect everyone — not just the roughly 8 percent of Californians without insurance — including people on Medicare and private, employer-sponsored insurance, plans that are generally well-liked.

Two-thirds of the Assembly and Senate also must approve the tax increases required to fund it.

And even if it were to clear the Legislature and be signed by Democratic Gov. Jerry Brown, it would need cooperation from Trump’s administration to waive rules about federal Medicare and Medicaid dollars.

The idea to increase the government’s role in health care comes as Trump and congressional Republicans look to reduce it. The conservative House Freedom Caucus on Wednesday announced its support for a newly revised GOP health care bill, a month after its opposition forced Republican leaders to pull the legislation.

California lawmakers have considered single-payer health care several times before. The Legislature approved a single-payer bill in 2007 but it was vetoed by then-Governor Arnold Schwarzenegger.

More recently, Vermont abandoned an attempt to create a single-payer system when cost estimates came in high. Colorado voters last year rejected a ballot measure that would have created the system. 

“By having everything in one pool, you’re going to decrease administrative costs, and you’re also going to get away from a system where so many different players in the system are there only because of greed, because they want to make money off of people’s health care needs,” said Thorild Urdal, a nurse in Oakland who is originally from Norway, which has government-funded health care.

Bison calves have been born in the area that makes up Alberta’s Banff National Park for the first time in 140 years, Parks Canada officials said Tuesday, marking a milestone in attempts to reintroduce a wild herd to the area.

Conservation officers said three calves had been born since Saturday in the remote Panther Valley on the eastern slopes of the Rocky Mountains and that seven more were expected.

Western Alberta is dealing with unseasonably cold spring weather, but Bill Hunt, resource conservation manager for Banff National Park, said the calves were well-equipped to deal with harsh conditions.

“Last night, we had 2 to 3 feet (60 to 90 centimeters) of snow, but fortunately bison are very well-adapted, so these little calves drop out, get their legs straightaway, start nursing and do fine,” Hunt said.

Parks Canada released a 16-strong herd of plains bison, including 10 pregnant females, in the country’s oldest national park in February.

They are keeping them under observation until summer 2018, when the animals will be released into the full 460-square-mile (1,189-square-kilometer) reintroduction zone after the females calve again next spring.

Bison herds of up to 30 million animals once migrated freely across North America. The shaggy, hump-shouldered animals, also widely known as buffalo, were nearly hunted to extinction in the late 19th century. Rangers estimate that bison have not grazed in Banff National Park since before it was established in 1885.

Dating app Tinder is hit or miss for humans, but wildlife conservationists hope it might lead to love for the world’s last male northern white rhino.

The move is seen as a last-ditch effort to keep the species alive.

“I don’t mean to be too forward, but the fate of the species literally depends on me,” the rhino’s profile says. “I perform well under pressure.”

Sudan is 43 years old, weighs nearly 2,270 kilograms and lives in Kenya. And while he has two female companions, they are unable to mate due to age and other limitations.

The campaign to find love for Sudan, called Most Eligible Bachelor by the Kenyan Ol Pejeta Conservancy, which came up with the idea.

While it’s unclear if any potential mates can swipe right on Sudan’s profile, the group hopes the move will raise $9 million for research into breeding methods such as in vitro fertilization.

“We partnered with Ol Pejeta conservancy to give the most eligible bachelor in the world a chance to meet his match,” said Matt David, the head of communications and marketing at Tinder in an interview with the Associated Press. “We are optimistic given Sudan’s profile (it) will be seen on Tinder in 190 countries and over 40 languages.”

Sudan and his two female friends — 17-year-old Najin and 27-year-old Fatu — live at the conservancy protected by 24-hour security.

“The plight that currently faces the northern white rhinos is a signal to the impact that humankind is having on many thousands of other species across the planet,” Richard Vigne, the conservancy’s chief executive officer, told AP. “Ultimately, the aim will be to reintroduce a viable population of northern white rhino back into the wild, which is where their true value will be realized.”

A type of worm could help solve the growing problem of plastic pollution.

The common wax worm, or Galleria mellonella, researchers say, can eat plastic and could help reduce the waste caused by the one trillion polyethylene plastic bags used around the world annually.

“We have found that the larva of a common insect, Galleria mellonella, is able to biodegrade one of the toughest, most resilient, and most used plastics: polyethylene,” says Federica Bertocchini of the Institute of Biomedicine and Biotechnology of Cantabria in Spain.

The discovery about the caterpillar’s hunger for plastic was accidental, said Bertocchini, adding that the plastic bags containing the wax worms “became riddled with holes.”

She said the worms can “do damage to a plastic bag in less than an hour.” And after 12 hours, researchers saw “an obvious reduction in plastic mass.

They also found that the worms transformed polyethylene into ethylene glycol, an organic compound used in making polyester fibers as well as antifreeze. It is unclear if the worms produce enough to be commercially viable.

Plastic is not the natural food of the wax worm, but researchers say that since they lay their eggs in beehives, the hatchlings feed on beeswax.

“Wax is a polymer, a sort of ‘natural plastic,’ and has a chemical structure not dissimilar to polyethylene,” Bertocchini says.

Researchers say they still need to better understand how wax is digested, but that finding out could lead to a biotechnological solution to plastic waste.

“We are planning to implement this finding into a viable way to get rid of plastic waste, working towards a solution to save our oceans, rivers, and all the environment from the unavoidable consequences of plastic accumulation,” Bertocchini says. “However,” she adds, “we should not feel justified to dump polyethylene deliberately in our environment just because we now know how to biodegrade it.”

The study was published in the journal Current Biology.

India is plundering the land of its indigenous people to profit from mining, with little regard of the devastation caused to poor tribal communities, said an Indian land rights activist who won the prestigious Goldman Environmental Prize on Monday.

Prafulla Samantara, 66, from India’s eastern state of Odisha is one of six winners of the annual prize — often known as the “Green Nobel” — which honors grassroots activists for efforts to protect the environment, often at their own risk.

Samantara, recognized by the Goldman jury for winning a 12-year legal battle to stop a multi-national firm mining bauxite on tribal lands, said he was honored by the award but voiced concern at the continued mining threats faced by India’s tribes.

“The state has a history of not honoring legal protections of indigenous people in the constitution. Corporate influence and the promise of profits continues to tempt the government to disregard indigenous people’s rights,” Samantara told the Thomson Reuters Foundation in an interview.

“The mining-based industry has become priority for the government and the global market, but it does not support the common people. They are often led to believe that mining is for their own benefit, but then they are displaced by destructive development.”

India’s tribes make up almost 10 percent of its 1.3 billion population. Yet most live on the margins of society — inhabiting remote villages and eking out a living from farming, cattle rearing and collecting and selling forest produce.

Many live in mineral-rich regions such as Odisha, Madhya Pradesh, Chhattisgarh and Jharkhand, and risk being chased off their ancestral land due to a rising number of mining projects.

While their land is protected under a decade-old law known as the Forest Rights Act, few know their rights — leaving them open to exploitation.

Fast-track

Since Prime Minister Narendra Modi’s government swept to power almost three years ago, it has taken a pro-business approach by fast-tracking environmental clearances for mining firms in a bid to boost investment, jobs and growth.

The son of a village farmer who went on to college to study economics and then law, Samantara led a battle against the London-headquartered Vedanta Resources which wanted to mine bauxite from a mountain considered sacred by indigenous people in Odisha.

He was kidnapped, assaulted and attacked for his activism against, but in the end, a vote of villagers — which had been ordered by the Supreme Court — rejected the mine.

Samantara — described by the Goldman jury as an “iconic leader” — slammed the government for blocking the foreign funds of thousands of charities, including green groups.

“It is deplorable. Many are fighting legally and are being targeted by the government,” he said.

Despite increasing threats to the environment and to those fighting to protect it, Samantara said he remained optimistic.

“I feel there is a growing threat to the very existence of Mother Earth if man-made destruction of nature is not stopped. But I see a ray of light,” he said.

“Though my contributions may be a drop in the ocean, thousands like me in the world can bring a radical change in thinking and spur action, encouraging a shift from consumption to preservation and conservation for future generations.”

The Goldman Environmental Prize was established in 1989 by San Francisco philanthropists Richard and Rhoda Goldman and provides $175,000 cash award to each individual.

Other winners were Congolese Park Ranger Rodrigue Katembo, Guatemalan land rights activist Rodrigo Tot, Australian family farmer Wendy Bowman, Slovenian organic farmer Uros Macerl and a Los Angeles community organizer by the name of Mark Lopez.

An experimental blood test can quickly and accurately diagnose malaria from other infections, so treatment of the mosquito-borne illness can be started promptly. 

The symptoms of malaria, which strikes an estimated 200 million people around the globe every year, are non-specific.  That means the fever, aches, pains and chills in the early stages could be mistaken for any number of infections. 

Identifying and treating malaria promptly not only increases a patient’s chances of survival, but also helps prevent the disease from spreading to more people.

The blood test, developed by researchers at Stanford University in California, looks for patterns of immune system activation to determine whether a person is infected with the malaria parasite, and not a bacterium or virus.  It is reportedly 96 percent accurate.

Purvesh Khatri, a professor of medicine at Stanford, helped develop the biomarker test, which looks at which genes are switched on or off, depending on the infection.

A simple blood test measuring these immune markers could be helpful in resource-poor settings, according to Khatri. 

“So a test like ours is useful,” he said, “You could take a blood test that would not require an expert technician, and they are more sensitive than the rapid diagnostic test than we have now.”

Khatri notes the current test is not very accurate because it looks for a molecule, called an antigen, that activates an immune response in a malaria infection. 

“And the problem with those are there are not enough antigen,” said Khatri.  “So treatment then [could] be inappropriate and then it could awhile before malaria is diagnosed.”

Khatri and his team drew upon data from 40 studies involving more than 3,000 blood samples from patients with various infections.  Some were known to have malaria.  But there were also other tropical illnesses observed in the studies, including dengue, typhoid and leishmaniasis.

From those blood studies, investigators analyzed the activation of 2,100 different genes, looking at which genes switched on and off with parasitic, viral and bacterial infections.

They found a group of seven genes that were expressed in malaria compared to healthy people and those with other infectious illnesses.

To confirm their discovery, the researchers whittled the samples down to 900, in which they were able to discern the pattern of gene activation unique to malaria with near 100 percent accuracy.

While the experimental blood test is accurate in diagnosing malaria, Khatri says it might also detect other parasitic diseases that researchers have not yet studied.

But he said the blood test could be reliably used in cases where malaria is strongly suspected and confirmation of the disease is needed.

Khatri presented his findings at a meeting of the European Congress of Clinical Microbiology and Infectious Diseases before World Malaria Day this week.

After an unprecedented global rally in support of science-based policymaking, organizers of last Saturday’s March for Science say the real measure of success will be whether they can translate the event’s enthusiasm into action.

After crowds rallied in Washington and more than 600 other locations around the world April 22, march planners now urge those who participated to go out into their communities and advocate for science.

“WE MARCHED. NOW, WE ACT,” reads the updated March for Science website, which lays out It lays out a week of action. Suggestions for Monday target local engagement: Start science game nights or book clubs, for example. Tuesday calls for contacting policymakers on science issues.

The more than 260 groups that backed the march also are urging their members to stay engaged.

The American Geophysical Union (AGU), which represents 60,000 earth and space scientists, has five weeks of action planned, with a similar strategy: Write your representatives; speak in your community; organize.

Symptom

As a scientist-led movement, the March for Science is unprecedented in its size and reach. It is a symptom of the concern that has been building in the scientific community. Scientists say ideology has overtaken evidence as the basis for policy on climate change, vaccines and much more.

“Certainly, though, recent political events in the U.S. and around the world have heightened that incentive” to mobilize, said AGU Executive Director Chris McEntee. “So, we are seeing larger and larger numbers of our members who want to participate.”

Others are seeing the same thing. The union representing Department of Energy employees says membership has grown 30 percent in the last four months. Advocacy group Union of Concerned Scientists (UCS) has added about 3,000 members to its network of scientists, engineers, economists and other experts. The science network now tops 20,000.

“There’s just a lot of energy out there,” said Andrew Rosenberg, director of the UCS Center for Science and Democracy. “People want to know what they can do. And many, many people in the science community realize that retreating to your lab and hoping things go OK is just not sufficient in the current climate.”

Some have decided it’s time they step into the political arena. About 5,000 scientists have announced plans to run for office since the beginning of this year, according to 314 Action, an advocacy group that champions scientists seeking elected office.

“That is five times more than our most optimistic projection,” said Shaughnessy Naughton, who founded 314 Action after an unsuccessful run for Congress in 2016.

Scientists have felt under attack since before the Trump administration, she said. But Trump’s hostility to climate science “certainly has been a catalyst for getting more scientists to say, ‘Enough. I can’t just write another polite letter. I need to step up and get more involved.'”

U.S. astronaut Peggy Whitson on Monday broke the record for most accumulated time spent in orbit by an American.

Commander Whitson, who is aboard the International Space Station, was congratulated by U.S. President Donald Trump, who spoke to space station astronauts via video.

“Five-hundred thirty-four days and counting. That’s an incredible record to break,” Trump said from the Oval Office. “On behalf of our nation, and frankly on behalf of the world, I’d like to congratulate you.”

WATCH: Trump congratulates Whitson

The 57-year-old Whitson is the most experienced U.S. spacewoman. She is scheduled to return to Earth in September, at which time she will have spent 666 days in space over the course of three flights.

“It’s actually a huge honor to break a record like this,” Whitson told Trump.

The two also discussed the potential for further space travel, including to Mars, which NASA has said it wants to accomplish by the 2030s. However, Trump moved that deadline up, telling Whitson that he’d like to see a Mars trip “at worst, during my second term.”

It wasn’t immediately clear whether the president’s comments were meant to be taken literally.

Whitson also explained to Trump how technology in the space station allows astronauts to convert their urine to drinking water. “It’s really not as bad as it sounds,” she said.

“Well that’s good, I’m glad to hear that,” Trump responded. “Better you than me.”

Trump also spoke with U.S. astronaut Jack Fischer, who arrived at the space station for the first time last week. Asked by Trump how his flight went, Fischer, an Air Force pilot, responded: “Sir, it was awesome. It made even my beloved F-22 feel a bit underpowered.”

Trump, who was speaking alongside his daughter Ivanka Trump, said he was honored to speak with the astronauts.

“I’ve been dealing with politicians so much. I’m so much more impressed with these people, you have no idea,” he said.

The World Health Organization has announced that trials of a new malaria vaccine will take place in three African countries – Kenya, Ghana and Malawi. They have been selected for their high prevalence of malaria and strong existing immunization programs for other diseases. The announcement was made ahead of the U.N.’s World Malaria Day Tuesday – and the chosen theme for this year is ‘a push for prevention’.

Malaria remains one of the world’s deadliest diseases – killing close to half a million people every year, mostly in Africa. So the testing of a new vaccine called RTSS has been greeted as a great step forward. It’s hoped that 360,000 children will be vaccinated between 2018 and 2020 in Kenya, Ghana and Malawi.

The World Health Organization’s Regional Director Dr. Matshidiso Moeti made the announcement Monday in Nairobi.

“We are very appreciative that GSK the pharmaceutical company that is developing the vaccine will provide this for free of charge for this pilot,” she said. “And the vaccine will be assessed as the complementary intervention in Africa that can be added to our existing tool box of proven preventive diagnostic and treatment measures.”

While a malaria vaccine would be an invaluable tool, other methods remain vital in preventing malaria.

Dr. Thomas Churcher of Imperial College London uses mathematical modeling to highlight the best way of killing of blocking the main vector that transmits malaria – the mosquito.

“Currently the majority of control is through the use of bed nets, but there’s an increasing fear that mosquitoes are becoming resistant to some of the insecticide on those bed nets,” he said. “And so therefore there’s a chance that a control that works today might not work as well in the future. And so we need new ways of killing mosquitoes, new types of bed nets, new types of drugs, new types of vaccines.”

Global efforts to reduce transmission have led to a two-thirds reduction in malaria deaths between 2000 and 2015. It’s hoped the development of a vaccine will get us one step closer to one day eradicating the disease, says Churcher.

“Hopefully one day we will have a vaccine that’s good enough to be that silver bullet. The current vaccine can do an awful lot but it’s not going to completely halt malaria transmission,” he said. “The recent studies show that it’s partially effective, and that that effectiveness wears off quite quickly over time.”

The $50 million trials in Ghana, Kenya and Malawi are being funded through a network of NGOs and global institutions. Far greater investment will be needed to roll the vaccine out globally – if the pilots prove successful.

Concerted campaigns in the Greater Mekong Subregion [GMS] to radically reduce the impact of malaria has lifted hopes a vital target to eradicate malaria from the region may be within reach.

Deyer Gobinath, a malaria technical officer with the World Health Organization (WHO) in Thailand, said the outlook is positive for eliminating severe forms of malaria across the region within the next decade.

The goal is for most of the GMS countries by 2025 to try and eliminate falciparium malaria – the most severe form of malaria – the falciparium malariia – and then by 2030 basically all forms or all species of malaria,” Gobinath said.

In 2015, WHO leaders said there were 14 million malaria cases across Southeast Asia, resulting in 26,000 deaths.  Globally, in the same year, the WHO reported 438,000 lives lost, mostly in Africa and warned that 3.2 billion people – almost half the world’s population – face health risks from the disease. 

Mortality rates decline; challenges remain

The campaigns in Southeast Asia cover Myanmar, Laos, Thailand, Cambodia and Vietnam, all reporting consistent declines in mortality rates, by as much as 49 percent since 2000.

Populations most vulnerable to the mosquito-borne disease are largely in remote border regions, isolated from infrastructure and immediate medical support.

The key areas of concern lie in regions between Thailand and Myanmar – also known as Burma – and in Cambodia among others.

But Saw Nay Htoo, director of the Burma Medical Association, said collaboration between medics and local communities has had a positive impact in reducing malaria’s impact.

“In the ground level we set up the malaria [clinic] post which we have at least one malaria health worker, according to the population they have, to detect malaria,” he said. “And if there is malaria positive then the patient is given the malaria medicine. So we have been doing this for three years. It seems our program is going very well – there are less malaria cases in the border areas.”

Combination of drugs

The fight against malaria is largely based on a combination of drugs known as Artemisinin-based Combination Therapy, or ACT, as the main line of drug treatment.

The World Health Organization’s Gobinath said Thailand’s medical infrastructure and funding support have all contributed to lowering the numbers of malaria cases.

“For malaria in Thailand here’s been quite a remarkable decrease – a steady decrease, decline in the number of confirmed cases of malaria. In the past 10 years or so something like 30,000 cases in 2012; to 2015 it was 19,000 to 20,000 cases. So it’s been a gradual but persistent decline of confirmed malaria cases,” he told VOA.

But he said for progress to be sustained it will require continued “political will and commitment.”

WHO officials said attention needs to focus on migrant worker populations moving across the region’s borders. Thai health authorities have taken steps to enable medical access to migrant populations at risk of malaria, largely in remote border areas.

The battle far from over

But challenges remain, said Maria Dorina Bustos, a WHO technical officer with responsibilities for monitoring drug resistant strains of malaria across 18 countries in the Asia Pacific.

Dorina Bustos said the region with drug resistant forms of malaria is spreading. “The Thai-Cambodia or the Thai-Myanmar border, you need to think about the Thai-Laos border because the Southern Laos drug resistance is also about evident – is documented, it is also there. And what is actually more alarming is happening in the Cambodia side,” she told VOA.

She said drug resistance becomes evident in the delay in clearance of the parasite from the patient. Dorina Bustos says the use of fake drugs and self-treatment also opens the way to drug resistance.

“What we are seeing in the last five years is that it is really emerging in the most parts of the region – initially just in the Western border of Cambodia and now it has also spread to the east and almost the whole country,” Dorina Bustos said.

She said there is a need for close monitoring of major population centers – especially in India and Africa – to ensure successful treatment and avoiding issues of the use of fake medicines.

A positive note has been ongoing investment and research in new drugs, including commitments by major pharmaceutical industries.

“It’s really here in the Mekong where we really have a problem. Cambodia, the borders of Thailand, the borders of Thai/Laos and Cambodia/Vietnam – it’s very specific in the Mekong region,” she said. “For Malaysia, the Philippines, Indonesia, Solomon Islands, Vanuatu and even India, Bangladesh and Nepal the ACT [Artemisinin-based Combination Therapy] is all working perfectly well.”

This year marks the half-way point in an international campaign to provide children and adults the world over with access to life-saving vaccines. VOA’s Carol Pearson reports on the progress – and what’s at stake in this campaign.
…

Six years ago, 194 countries signed on to the Global Vaccine Action Plan, an international campaign to provide children and adults around the world with access to life-saving vaccines.

The goal of the program is to prevent millions of people from getting vaccine-preventable diseases by the time it ends in 2020. The idea is to provide universal access to vaccines to protect people of all ages, from the very young to the very old.

Dr. Flavia Bustreo, is the assistant director-general for Family, Women’s and Children’s Health at the World Health Organization.

“Immunization and vaccines are the most powerful public health tools that we have currently, “ she said.

Millions of children saved

Bustreo says 35 years ago, 13 million children lost their lives from diseases that could be prevented by vaccines.

She says that number has been reduced to 6 million, but 6 million is still too high.

Today, 85 percent of children are vaccinated against measles and other deadly diseases, but Bustreo says more children need these vaccines.

“We need to have vaccination coverage that is about 90 percent, in order to have what we call the ‘herd effect’ … which means you cover the children who are vaccinated, but also, because of the reduction of transmission of infections, you also cover the children that are not vaccinated,” Bustreo said.

Final push on polio

Because of vaccines, polio is on the brink of eradication. Polio exists in two conflict zones: in northern Nigeria and along the border between Pakistan and Afghanistan. Last year there were 37 cases. Compare that to the 350,000 cases in 1988 when the eradication campaign began.

There’s a special urgency to vaccinate all children against polio. Dr. David Nabarro has worked on a number of health programs at the World Health Organization and now as a special envoy for the United Nations.

“The last part of eradicating any disease is always the hardest part,” he said. “If you don’t do it, you lose everything. To do it, you’ve got to really bring all the energy and commitment you can to bear, and it requires a special kind of dedication.”

Vaccines have prevented millions of deaths and countless numbers of children from becoming disabled. By 2020, at the conclusion of the Global Vaccine Action Plan, the U.N. wants to see countries strengthen routine immunizations for all children. It wants to complete the effort to end polio and to control other vaccine-preventable diseases. Also, the goal is to be well on the way in developing new vaccines for other diseases that plague our world.

Drawn-out deaths. Communities torn apart. Survivor’s guilt. Patrick Fallah says his memories of the days when the Ebola virus swept through Liberia are so awful that he sometimes has trouble focusing on the present.

“Sometimes when I have a flashback of the death of my son and others who died in the Ebola treatment unit, I don’t want to speak to people. I grieve so much that my mind is not really on what I am doing,” said Fallah, 30, who lost his 8-month-old son and stepmother and is president of the National Ebola Survivors Network of Liberia.

The trauma of the world’s deadliest Ebola outbreak, which killed more than 11,300, mostly in Liberia, Sierra Leone and Guinea, has left many survivors fighting a battle some worry will never end.

But Liberia, one of the world’s poorest countries and with just one psychiatrist, has announced the ambitious goal of expanding access to mental health care to 70 percent of its population in the next few years.

The World Health Organization declared an end to the Ebola outbreak in June, estimating that more than 10,000 people who had been infected have survived in the three West African countries, including more than 4,000 in Liberia.

As the world’s attention has turned to other crises, many Ebola survivors still face the psychological consequences of the epidemic, feeling guilt over their pasts and worry for their futures without resources to deal with the pain.

Mental health is often an expense far beyond the reach of impoverished countries. Liberia is still struggling to rebuild its basic health services after more than a decade of back-to-back civil wars that left a quarter-million people dead, with many killings carried out by drugged, under-age fighters notorious for hacking off survivors’ limbs.

Then Ebola arrived, frightening Liberians with its lack of a cure and its transmission through contact with body fluids. Many people became too scared to touch others or offer comfort as the death toll grew.

Now Liberia’s government has announced its ambition to expand mental health care access to its more than 4.2 million people, with help from the U.S.-based The Carter Center.

“After the civil war, people didn’t go through enough counseling. You have people already going through post-traumatic depression. Then Ebola came, and that built on what was already going on,” said Dr. Francis Kateh, Liberia’s deputy health minister and chief medical officer.

The Carter Center is helping to train Liberia’s health care workers to identify mental health issues.

Last month, 21 clinicians specializing in child and adolescent mental health graduated from the training. They join 187 mental health professionals who have been trained by the center since 2010 to work in prisons, with refugees or in other settings and are based in primary care clinics and hospitals around the country.

The Carter Center hopes to replicate its program in other countries, including Sierra Leone.

But educating the public will take time, the new mental health workers say.

“There are many people living with mental health problems in Liberia without knowing they are,” said one of the new specialists, Theophilus A. Joe.

Stigma remains around mental health issues, said Musulyn Massaqoui, a registered nurse and another recent graduate. Most people come to clinics only for physical issues, she said.

Ebola survivors often have hearing and vision problems, joint pain or chronic fatigue, according to the medical aid charity Doctors Without Borders. Many also are shunned by their communities and family members, making them vulnerable to mental health issues.

Children left orphaned by Ebola or who watched family members die are especially challenged, said Fallah with Liberia’s survivors’ network, which has about 1,800 members.

“They continue to have depression. They are still thinking about their parents,” he said. “Sometimes when they sit in the class, they don’t concentrate.” During the holidays, some feel so neglected that they “want to take up knife to kill themselves.”

Some of Liberia’s newly trained mental health workers have been placed in schools and orphanages to lessen the chances of stigma, said The Carter Center’s mental health program director, Eve Byrd.

That approach is critical, she said. “If you address childhood trauma early, you’re most likely to decrease symptoms of illness as the person ages.”

Stigma in Liberia has proven to be deadly. In March, an Ebola survivor who made the cover of Time magazine for her work as a nurse during the outbreak died when she experienced complications after childbirth and the nurses on duty were too afraid to touch her.

European scientists are taking part in the March for Science demonstration taking place in hundreds of cities around the world to commemorate Earth Day. Science and research skeptics are becoming more mainstream in an era of populist and Eurosceptic movements. And on both sides of the Atlantic, there is less funding to support independent research.

Jean-Pascal van Ypersele, a professor at the University of Leuven, says shifting priorities in Europe has had an impact on the work of scientists.

“Now funds for fundamental research are much more difficult to get. Even if the budget remains the same or sometimes has increased, there was a shift in priorities towards research that is supposed to deliver more immediate results in terms of job creation or that kind of thing. Or research that helps the European industry to bring a product to the market. And climate scientists are not building any products that the European industries can sell.”

The European Union set a target for its member states that they should spend three percent of their budget on science, but many countries are only at around two percent.

Scientists hope that by joining forces globally, they will raise awareness about a global trend that seems to take science less serious. With U.S. President Donald Trump in the White House and populist and Eurosceptic movements gaining popularity in Europe, scientists say their budgets are being reduced and their work is being taken less serious.

Bas Eickhout, a scientist and member of the European Parliament for the Greens Party, says climate change policy should not be seen as a “left wing hobby.” He calls on scientist to be more involved in the decision making process.

“Not in policy making itself but providing information to politicians is crucial. And quite often once we start with decision making, that information is just lost. Scientist are really a bit too scared for the word lobby, and I don’t think its lobbying that your doing, but its also trying to feed decision making also during the negotiations, and not only at the beginning.”

The March for Science is a volunteer based movement and organizers say there is an “alarming trend toward discrediting scientific consensus and restricting scientific discovery.” The organizers aim to celebrate science and hold political and science leaders accountable, but do not affiliate with any political party.

Sofie Vanthournout, director of Sense about Science EU, a charity advocating the importance of science, says the march aims to change the perspective of citizens and politicians who doubt the importance of science:

“The message that we want to bring it is important for every aspect of our lives, for every aspect of society. Whether it’s in technology that we use in our daily lives or whether it is for important decisions that politicians make about our lives. We don’t want scientists to tell politicians what to do but we need the politicians to have access to all of the facts and all of the knowledge that is available.”

One week after the March of Science, the Peoples Climate March will follow. In 2015, the world came together to sign the Paris Accord, an agreement signed by almost all nations in the world to curb global warming.

U.S. President Trump promised during his election campaign to pull the United States out of the international accord, but later softened his stance, saying he thinks there is “some connectivity” between human activity and global warming.

Scientists are taking the unprecedented step of staging marches in more than 600 cities worldwide in the face of what they see as a growing political assault on evidence-based knowledge.

Thousands of scientists and their supporters are attending March for Science events Saturday across the globe, including those in Australia, Brazil, Canada, Cape Town, London Madrid, Nigeria and Seoul.

In Berlin, organizers said about 10,000 people marched toward the Brandenberg Gate holding up placards that read “Facts not feelings” and We love experts — those with evidence.”

Marchers in Geneva carried signs that said “Science — A candle in the Dark” and “Science is the Answer.”

In London, demonstrators marched from the Science Museum to Parliament Square in Westminister holding placards supporting science.

The March for Science thrusts scientists, who generally avoid advocacy and whose work is based on impartial experimentation, into a more visible spotlight.   

For nuclear physics graduate student Chelsea Bartram, White House adviser Kellyanne Conway’s “alternative facts” were the last straw.

President Donald Trump had disputed photographic evidence of the size of his inauguration crowd. Reporters challenged him, prompting Conway to respond that the administration gave “alternative facts.”

“Many scientists I know, myself included, spend so many hours in the lab sacrificing enormous amounts of their life for this abstract idea” that understanding reality can benefit human civilization, said Bartram, who is pursuing a doctorate at the University of North Carolina at Chapel Hill.

“And then to have someone say, ‘Well, that’s not important anymore,’ it’s so devastating,” Bartram added.

So Bartram planned to support science’s role in government decisions on health, safety, the economy and more by joining demonstrators at the flagship March for Science event in Washington.

The Washington event featured speakers and several large teach-in tents on the National Mall where scientists, educators and leaders from a variety of disciplines discussed their work, effective science communication strategies and training in public advocacy. Organizers say the event is non-partisan and is not aimed against the Trump administration or any politician or party.

Organizers of the international event, which coincides with Earth Day, say it is the first step in a global movement to acknowledge and defend the vital role science plays in everyday life.

“Science extends our lives, protects our planet, puts food on our table (and) contributes to the economy,” says Caroline Weinberg, national co-chair for the March for Science.

“Policymakers threaten our present and future by ignoring scientific evidence when crafting policy, threatening scientific advancement through budget cuts and limiting the public’s knowledge by silencing scientists,” Weinberg said.

Trump’s most recent budget proposal calls for cuts to the Environmental Protection Agency (EPA) that would eliminate some 56 programs and drastically reduce funding for the agency’s Office of Research and Development and Science Advisory Board. Trump’s budget proposal also recommends some $6 billion in cuts to the National Institutes of Health, the largest public funder of biomedical research funding in the world.

Dr. Mona Hanna-Attisha, a first-generation Iraqi immigrant, is the pediatrician who alerted officials in Flint, Michigan that the city’s water was contaminated with lead. She is a March for Science honorary national co-chair. “We march for science so that scientists have the freedom like I did, to speak out, free from politicization and to continue to make the world a better place.”

Tipping point

Organizers have not released expected crowd size estimates. But the dispute over crowd sizes was just one small example of what scientists see as a larger pattern. During the U.S. presidential campaign, Trump dismissed the scientific consensus about the dangers of human-induced climate change. His appointee to lead the EPA, Scott Pruitt, also does not accept climate science. He has repeatedly clashed with the agency he now heads.  

But scientists say their frustration has been building for decades.

“We might have reached a tipping point now, but acting as though this is a new thing is giving too much credit to the current administration,” said Weinberg.

And it goes far beyond climate change, Weinberg added. “It’s about not paying attention to the best research on things like food stamps. It’s about cutting things like Head Start and after-school programs,” to name a few. “And that all affects health, because that’s a time to set kids on the right path.”

Critics say a public protest risks further politicizing science, turning scientists into just another interest group.

Bartram sums up a widespread response: on hot button issues like climate change, opponents have already done it. “I don’t think anything we do is going to further politicize it,” she said.

Disconnect

But if the goal is to get policymakers to listen, “A march isn’t going to change anything,” said Rob Young, head of coastal research at Western Carolina University.

Young says much of the problem stems from the growing disconnect between scientists and voters, especially the rural and working class people who voted for Trump. He says most probably have never met a scientist.

Scientists need to get out of the lab more, he said, and explain how their work affects people’s health and livelihoods.

That’s what march organizers hope, too.

The American Geophysical Union’s Davidson said a major post-march goal is more public engagement.

“I think the day is gone when scientists can stay in their ivory towers and assume that everyone is going to recognize their value,” he added.

The founder of Microsoft, billionaire philanthropist Bill Gates, has given a passionate defense of foreign aid while voicing fears the political climate in the U.S. and in Britain could result in cuts to aid budgets. In a speech this week in London, he warned that withdrawing aid would “create a leadership vacuum that others will fill.”

Gates, who gives $5 billion a year to development aid through the foundation he set up with his wife, Melinda, is one of the world’s most generous philanthropists. In a speech at London’s Royal United Services Institute this week, he voiced fears that the political tide is turning against foreign aid.

“It concerns me that some world leaders are misinterpreting recent events as reasons to turn inward instead of seeing them for what they are: problems that although they are difficult and will take time, can be solved — if we invest in the long-term solutions that are necessary,” Gates said.

Watch: Billionaire Philanthropist Bill Gates Warns Against Cuts to Aid Budgets

The United States remains by far the world’s biggest donor, funding long-term programs and emergency relief across the globe. But President Donald Trump is proposing significant cuts to the $43-billion foreign aid budget as part of efforts to reduce government debt.

Gates argues that many critics of foreign aid don’t realize the major progress that has been achieved.

“If you could only pick one number to highlight the effectiveness of the development agenda since 1990, I would pick the number 122 million. That’s the number of children’s lives that have been saved,” he said.

He disputed the notion that funding foreign aid is a bottomless pit.

“As you bring down that childhood death rate, families choose to have less children,” he said. “The population goes down very substantially. Which brings within reach all of the things society is trying to do: better health, better education, economic opportunity.”

Gates’ speech in London comes as Britain gears up for a snap election in June. The UK is one of the few developed countries to meet the U.N. aid budget target of 0.7 percent of GDP. Current Prime Minister Theresa May has committed to keeping that pledge but many in her party want aid money diverted to the military.

Gates said he wanted to make the case for the facts.

“When aid is mismanaged it is a double crime, stealing both from the taxpayer and from the poor.” he said. “But let’s be clear. The bulk of this aid is getting to its recipients and having an incredible effect. There will always be a need to adjust, we’re working in very tough countries, so you’ll never get 100 percent perfect effectiveness. But you can learn. And every year, the aid is better spent.”

Aid agencies say the debate could not come at a worse time, with about 65 million refugees around the world, worsening conflicts in the Middle East and famine striking East Africa.

In 16 U.S. cities, citizen scientists, including schoolchildren, spent a few days this month documenting plant and animal species and helping scientists understand their regions’ diversity and the challenges many species face.

The City Nature Challenge, held April 14-18, is a competition that was started last year by the Natural History Museum of Los Angeles County and San Francisco’s California Academy of Sciences. This year, it involved institutions across the United States. The challenge is to see which city can document the most species; results are to be announced Saturday, which is Earth Day.

“Last year, it was San Francisco against Los Angeles,” said Lila Higgins, manager of citizen science at the Natural History Museum of Los Angeles County. “This year, it’s L.A. versus San Francisco and New York and Chicago and Seattle and many, many other cities.”

The young citizen scientists took photos and recorded observations on their cellphones, uploading the data through a phone app called iNaturalist.

Frank Az, 9, of Esperanza Elementary School in Los Angeles said he loves observing nature, “finding different species of birds and insects.” He was outside the museum with binoculars and a cellphone camera, along with other students.

His friend, Andrea Garcia, was excited as she described finding “two mourning doves in their nest” as well as “ants, bees and a house finch.”

The children worked with some adult scientists who monitor species in this region, including Greg Pauly, a specialist on amphibians and reptiles at the Natural History Museum. Pauly said that Los Angeles is one of the world’s 35 top biodiversity hot spots, but that the sprawling urban complex also faces “a large threat to that biodiversity.”

The children documented their sightings of insects, flowers and birds alongside their teachers. It is something they do regularly at school. Principal Brad Rumble of Esperanza Elementary said the migration of one bird species had captured the children’s interest.

“Every year, we do a contest to predict when will the yellow-rumped warbler first arrive on campus,” he said. The students vote, and those who correctly guess the date when the tiny visitor appears get a trip to the Natural History Museum.

“That little bird,” said Rumble, “brings up so many wonderings about geography and range and weather, and why does it like this tree? These questions form in students’ minds, and they’re off and running.”

The children are learning many lessons, said museum President Lori Bettison-Varga.

“We are part of this environment, and they are part of this environment — the plants, the animals, the critters that live here,” she said, “so it’s really helping us to understand how to increase the health of our environment.”

And this annual competition, she said, gets people of all ages involved in science.
