NIH Director Contradicts RFK Jr.'s Theory That Vaccines Cause Autism

“I have not seen a study that suggests any single vaccine causes autism,” Jay Bhattacharya, the director of the National Institutes of Health said, emphasizing that there has been no link found between the MMR vaccine and autism, but that other vaccines are “less well studied.”

The Hill: NIH's Jay Bhattacharya Refutes Vaccine-Autism Theory In Senate Hearing

Jay Bhattacharya, director of the National Institutes of Health (NIH), said in a Senate hearing Tuesday that he has not seen any studies supporting the theory that any vaccines cause autism, a break from Health and Human Services Secretary Robert F. Kennedy Jr., who has long speculated on a potential connection and has not discounted the possibility. In a hearing held by the Senate Committee on Health, Education, Labor, and Pensions, ranking member Sen. Bernie Sanders (I-Vt.) pressed Bhattacharya on where he stood when it came to the vaccine-autism theory. (Choi, 2/3)

Politico: ‘Efficacy Will Be Secondary’: RFK Jr.'s Vaccine Advisers Have A New Mission

Robert F. Kennedy Jr. fired the government’s vaccine advisers, replaced them with skeptics of the shots like himself and is now giving them a new mandate: investigating the harms of immunization. The Advisory Committee on Immunization Practices has for decades served as an impartial outside group of experts to advise the government and reinforce public confidence that decisions on the vaccine schedule are backed by science.

The Hill: Measles Case At UW-Madison Linked To International Travel

Health officials say the student contracted the illness during international travel and visited several UW-Madison campus locations. Health officials are now contacting all those who may have been exposed by interacting with the student. If you visited those locations, check your measles-mumps-rubella vaccine status immediately.
