Fact Check: Did the CDC end major measles outbreaks overnight or at record speed?

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: The CDC helped states bring measles outbreaks “to an end overnight” or at “record speed.”


Rating: BLATANT LIE


Explanation: Major U.S. measles outbreaks did not end overnight. Outbreaks in Texas, South Carolina, Utah and other states continued for months, and Utah’s outbreak had not officially ended when Kennedy made the claim. FactCheck.org found no evidence supporting the assertion that the outbreaks were stopped at record speed.
