President-elect Donald J. Trump chose Dr. David Weldon, a former congressman, on Friday to serve as the director of the Centers for Disease Control and Prevention.

Dr. Weldon, 71, is a native of Long Island and earned a medical degree in New York before moving to Florida to practice. Starting in 1995, he served seven terms in Congress, representing the 15th District of Florida, before forgoing re-election and returning to his medical practice.

As a member of Congress, Dr. Weldon pushed the false notion that thimerosal, a preservative compound in some vaccines, had caused an explosion of autism — a hypothesis that experts say has no evidence. He also introduced a “vaccine safety bill” that aimed to relocate most vaccine safety research from the C.D.C. — which he said had an “inherent conflict of interest” — to a separate agency within the Department of Health and Human Services.

Mr. Trump’s choice signals yet again his commitment to reforming the role of federal health agencies in radical ways. Though Dr. Weldon is an internist, his skepticism of vaccine safety and concern about C.D.C. overreach echo those of other nominees, including Robert F. Kennedy Jr.

“In addition to being a Medical Doctor for 40 years, and an Army Veteran, Dave has been a respected conservative leader on fiscal and social issues,” Mr. Trump wrote in a statement released Friday night, saying that Dr. Weldon would “restore the CDC to its true purpose.”

“Americans have lost trust in the CDC and in our Federal Health Authorities, who have engaged in censorship, data manipulation, and misinformation. Given the current Chronic Health Crisis in our Country, the CDC must step up and correct past errors to focus on the Prevention of Disease.”
