The Centers for Disease Control and Prevention is planning to conduct a large-scale study to re-examine whether there is a connection between vaccines and autism, federal officials said Friday.
Dozens of scientific studies have failed to find evidence of a link. But the C.D.C. now falls under the purview of Health and Human Services Secretary Robert F. Kennedy Jr., who has long expressed skepticism about the safety of vaccines and has vowed to revisit the data.
“As President Trump said in his Joint Address to Congress, the rate of autism in American children has skyrocketed. C.D.C. will leave no stone unturned in its mission to figure out what exactly is happening,” Andrew Nixon, a spokesman for the Department of Health and Human Services, said in a statement Friday.
Mr. Nixon did not offer details about the scope or methods of the project. News of the study was first reported Friday morning by Reuters.
In pursuing the study, the C.D.C. is defying the wishes of the chairman of the Senate Health Committee, Senator Bill Cassidy, who said this week that further research into any supposed link between vaccines and autism would be a waste of money and a distraction from research that might shed light on the “true reason” for a rise in autism rates.
“It’s been exhaustively studied,” Mr. Cassidy, a doctor, said during the confirmation hearing for Dr. Jay Bhattacharya, President Trump’s nominee to lead the National Institutes of Health. “The more we pretend like this is an issue, the more we will have children dying from vaccine-preventable diseases.”
