Rep. Byron Donalds, a Republican from Florida who is running for governor, has blamed “rampant illegal immigration” during the Biden administration for measles outbreaks. But we found no link to illegal immigration in several recent large outbreaks, and infectious disease experts told us that the main driver of the cases is falling measles vaccination rates in the U.S.
After the Pennsylvania Department of Health announced two cases of measles-related deaths in one county, the local coroner appeared to contradict the account. And in an ongoing spat with Pennsylvania Gov. Josh Shapiro, Health and Human Services Secretary Robert F. Kennedy Jr. has alleged that a Shapiro staffer may have even “fabricated” the deaths. We’ll lay out what we know.
Following an executive order that called for breaking up the combination measles, mumps and rubella, or MMR, vaccine, Health and Human Services Secretary Robert F. Kennedy Jr. said that a “recent” study “just came out” that “very strongly supports” the idea. But there’s no evidence of any such credible study, past or present.
During the signing of an executive order on vaccines, President Donald Trump and Health and Human Services Secretary Robert F. Kennedy Jr. made a deluge of false and misleading claims about the U.S. childhood vaccine schedule.
In signing an executive order about childhood vaccines, President Donald Trump falsely suggested that the measles, mumps and rubella, or MMR, vaccine was unsafe and that splitting up the combination shot would reduce the number of children with autism. There’s no evidence for those claims, and the vaccine has been well-studied for several decades.
In a contentious interview on CNN’s “State of the Union,” Health and Human Services Secretary Robert F. Kennedy Jr. made several false, misleading and baseless claims about the origins of Lyme disease and the respiratory syncytial virus, the COVID-19 pandemic, and what the science shows about autism, vaccination and acetaminophen use during pregnancy.
In defending his record on measles, Health and Human Services Secretary Robert F. Kennedy Jr. twice said during a recent Senate hearing, “We promote” the measles vaccine. While it’s true that the Centers for Disease Control and Prevention continues to recommend the shot, Kennedy has rarely made an unequivocal endorsement of it, even as the nation has seen an alarming rise in measles cases.
On Sept. 18, the vaccine advisory committee for the Centers for Disease Control and Prevention voted to change its recommendation on the combined vaccine for chickenpox and measles, mumps and rubella, called the MMRV vaccine. We spoke to experts about claims made at the meeting as well as the implications of the vote.
On four separate occasions, Robert F. Kennedy Jr., the Health and Human Services secretary, has suggested that the measles outbreak in Texas, which is now over 500 cases, is beginning to subside and grow more slowly. But a review of state data indicates there’s no decline yet in the pace of cases.
The measles vaccine uses a weakened virus that’s never been shown to spread to others. Samples from the outbreak in Texas also show that a wild-type virus is responsible. Yet, social media posts have falsely claimed that the outbreak is due to a vaccine strain. Without evidence, other posts have blamed immigrants crossing the southern border illegally.
