All such research is now under direct scrutiny from health secretary and long-time anti-vaccine advocate Robert F. Kennedy Jr.A senior official at the NIH's National Cancer Institute confirmed to KFF that NIH acting Director Matthew Memoli "sent an email across the NIH instructing that any grants, contracts, or collaborations involving mRNA vaccines be reported up the chain to Health and Human Services Secretary Robert F. Kennedy Jr.s office and the White House."Further, two independent scientists told the outlet that they were informed by NIH officials that any mention of mRNA vaccines needed to be removed from their grant applications. One, a biomedical researcher in Philadelphia, said that the NIH had "flagged our pending grant as having an mRNA vaccine component." The other, a researcher in New York who works on vaccines but not mRNA vaccines, was told that background mentions of mRNA vaccine efficacy in their previous grant applications needed to be removed from future applications.While it remains unclear if mRNA vaccine research funding will be canceled or limited, researchers fear the worst. Last week, news broke that the NIH was canceling or limiting grant funding for research related to vaccine hesitancywhich has increased significantly in recent years, leading to declining vaccination rates and the loss of herd immunity in many communities.Language for grant termination notices stated: "It is the policy of NIH not to prioritize research activities that focuses gaining scientific knowledge on why individuals are hesitant to be vaccinated and/or explore ways to improve vaccine interest and commitment," according to reporting from The Washington Post.Those terminations were preceded by an email from Memoli similar to the one he sent regarding mRNA vaccines, KFF reported. "It is reasonable to assume mRNA vaccine work is next," the NCI official told the outlet.Ars Technica has reached out to the NIH and HHS for comment and will update this story with any new information provided. The agencies did not respond to comment requests from KFF.Kennedys misinformationBefore becoming the top health official in America, Kennedy had long railed against vaccines, becoming one of the world's most prominent anti-vaccine advocates and most prolific spreaders of misinformation and disinformation about vaccines. A 2019 study found Kennedy was the single leading source of anti-vaccine ads on Facebook. Kennedy subsequently faced bans from YouTube, Facebook, and Instagram for spreading misinformation.Researchers directly blame Kennedy and the Trump administration for the attack on vaccine research."Kennedys war on vaccines has started," the mRNA vaccine researcher in Philadelphia told KFF."There will not be any research funded by NIH on mRNA vaccines," the scientist in New York similar told the outlet. "MAGA people are convinced that these vaccines have killed and maimed tens of thousands of people. Its not true, but they believe that."Kennedy has made various statements against vaccines generally, as well as mRNA vaccines specifically. He falsely claimed the vaccine causes severe harms, including causing neurodegenerative diseases, such as Parkinson's. In 2021, during the height of the pandemic, Kennedy petitioned the Food and Drug Administration to revoke the authorization of COVID-19 vaccines and refrain from approving any future COVID-19 vaccines. A study in 2022, meanwhile, estimated that the vaccines had saved more than 3 million lives and prevented more than 18 million hospitalizations.The NIH's recent moves aren't the first sign that Kennedy will use his powerful position to attack mRNA vaccines. Late last month, Bloomberg reported that HHS was considering canceling a $590 million grant to vaccine maker Moderna to develop mRNA vaccines against potential pandemic influenza viruses. That includes the H5N1 virus that is currently devastating US poultry and spreading wildly in dairy cows.An HHS spokesperson told media at the time that "While it is crucial that the US Department and Health and Human Services support pandemic preparedness, four years of the Biden administrations failed oversight have made it necessary to review agreements for vaccine production."It remains unclear what is happening with that grant review. Moderna declined to comment when Ars reached out for any potential updates Monday.Beth MoleSenior Health ReporterBeth MoleSenior Health Reporter Beth is Ars Technicas Senior Health Reporter.
