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.

If certain vaccines aren't recommended by the ACIP, it may lead to parents or guardians facing out-of-pocket costs if their children receive the shot. It could also mean the shots aren't covered by the Vaccines for Children (VFC) program, a federally funded program that provides no-cost vaccines to eligible children.
