The American Academy of Pediatrics issued vaccine recommendations that differ from U.S. Centers for Disease Control guidelines for the first time in 30 years.

The AAP published its own vaccine schedule in a break from federal guidance. HHS secretary RFK Jr. took to social media to respond.

The AAP’s other vaccine recommendations largely mirror those of ACIP. The new schedule also addresses recent updates on pentavalent meningococcal vaccine, the starting age of the human papilloma virus vaccine, and the removal of a hepatitis vaccine that is no longer available, according to the statement.

"The AAP urges every insurer to cover all the vaccines that are included in this immunization schedule," Kressley said. "AAP is committed to working with our partners at the local, state and federal levels to make sure every child, in every community has access to vaccines."
