RFK Jr. justified canceling mRNA vaccine funding by saying COVID vaccines:
-"encourage new mutations"
-"don't perform well" against respiratory viruses
-"pose more risk benefits"

All of those claims are false. More in NewsGuard's latest Reality Check: www.newsguardrealitycheck.com/p/rfk-jr-cit...

ICYMI: Researchers said RFK Jr.'s HHS twisted their work to justify shift on COVID vaccines during pregnancy.

HHS' response was to suggest NewsGuard was dismissing "significance of the underlying data," even when the study authors said HHS was wrong.

A HHS and RFK Jr. memo to Congress cited multiple studies to justify the agency’s new recommendation that pregnant women should not get a COVID vaccine.

But the actual study authors who spoke to NewsGuard said HHS misrepresented their work.

Joe Biden is not suffering from COVID vaccine-induced "turbo cancer" -- because that's not a real thing.

After Biden's cancer announcement on Sunday, it took only nine minutes for the first posts falsely blaming COVID vaccines to surface on X.

A new analysis by Stanford epidemiologists predicts that measles could become endemic again in the US in the next 20 years.

This would be a catastrophic failure and a result of anti-vax propaganda. Measles is a vaccine-preventable disease that was declared eliminated in the US in 2000.
Scientists Find Measles Likely to Become Endemic in the US Over Next 20 Years A new study forecasts more than 850,000 measles cases over the next 25 years if US vaccination rates stay the same. Millions of infections are possible if rates drop.

Some X and Telegram users, citing comments from RFK Jr., are falsely claiming that studies debunking vaccine-autism claims have not compared vaccinated and unvaccinated children.

In reality, multiple studies have done so, dating back to the 90s.

No, Dr. Fauci does not want to kill your cats to fight bird flu.

All Fauci did was accurately note that H5N1 has infected cats -- which a frequent misinfo source stretched into a cat-killing conspiracy.

Anti-vaxxers are mixing up correlation and causation (again) with the Texas measles outbreak, falsely claiming that an uptick in MMR vaccinations after the outbreak started means the vaccine itself is to blame.

Breaking: RFK Jr. has forced out PETER MARKS, the nation’s top vaccine regulator.

In his resignation letter, obtained by the Post, Marks said he was willing to work with RFK Jr on his vaccine concerns — but said Kennedy wishes “subservient confirmation of his misinformation and lies.”

RFK Jr.'s anti-vax group is now blaming the measles death of a 6-year-old on "medical error" -- all based on records the public can't see and a re-diagnosis by Dr. Pierre Kory, best known for falsely promoting ivermectin as a COVID cure.

The video racked up 1.2 million views in 5 days.
