RFK Jr. Cites Three False COVID Vaccine Claims to Justify Canceling mRNA Vaccine Funding Health and Human Services Secretary Robert F. Kennedy Jr. advanced three false claims about COVID-19 vaccines to explain his cancellation of $500 million in government-funded mRNA vaccine projects.

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...

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.

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.

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.
