CDC immunization schedule, United States
The CDC schedule is the immunization schedule recommended for children in the United States, set with the Advisory Committee on Immunization Practices and followed by pediatricians nationwide. It runs from a birth dose through the teenage years, and most visits are expressed as an age range rather than a single date, which gives families a window rather than a deadline.

Missed a dose?
If your child missed a dose or started late, most vaccines can be given on a catch-up basis. The schedule does not usually need to restart. Talk to your pediatrician, who can adjust timing safely for your child.
