Fact Check: Did a CDC study find that fewer than 1% of vaccine injuries are reported?

Media Bias Fact Check (MBFC) publishes daily vetted fact checks from verified IFCN-approved sources. Each claim is independently reviewed for accuracy and context.


Claimant: Robert F. Kennedy Jr.


Claim: A CDC study found that fewer than 1% of vaccine injuries are reported.


Rating: MISLEADING


Explanation: Kennedy cited a 2010 report that said fewer than 1% of vaccine adverse events were reported, but adverse events are health problems occurring after vaccination and are not necessarily caused by the vaccine. Other research indicates that serious adverse events are reported at substantially higher rates. (factcheck.org)
