Dr. Peter Marks, the top vaccine official at the Food and Drug Administration, wrote in a letter on Friday that he was resigning from his position and criticized Health and Human Services Secretary Robert F. Kennedy Jr., who has questioned the effectiveness of vaccines for years and promoted debunked claims that certain vaccines are linked to autism.

A large study into the potential connections between vaccines and autism is reportedly being planned by the U.S. Centers for Disease Control and Prevention, according to reports Friday.

It's not clear if Health and Human Services Secretary Robert F. Kennedy Jr. is involved in the study or how the plans would be implemented.

The CDC and Kennedy's department have not commented about the reporting, released by Reuters, which quoted two sources said to be familiar with the matter.

Health and Human Services Secretary Robert F. Kennedy Jr. on Wednesday appeared to downplay the seriousness of the West Texas measles outbreak that has killed a school-age child.

Nationwide, the rate of kindergartners with complete records for the measles vaccine declined from around 95 percent before the pandemic to under 93 percent last year, according to the Centers for Disease Control and Prevention. Immunization rates against polio, whooping cough and chickenpox fell similarly.

Average rates remain high, but those national figures mask far more precipitous drops in some states, counties and school districts.

Vaccination rates against childhood diseases have been on a downward slide for the past few years in the United States. Nationally, for example, the share of kindergarteners with completed records for the measles vaccine dropped to 93 percent last year, down from 95 percent in 2019, according to the Centers for Disease Control and Prevention. Polio, whooping cough, and chickenpox vaccination rates have likewise slumped since the pandemic.
