The Catch-Up Immunization Schedule organizes by age the vaccines and minimum time periods between doses for children whose vaccinations have been delayed. Note that a vaccine series does not need to be restarted, regardless of the time that has elapsed between doses.
If your child is 6 years of age or younger, you can use the Catch-Up Immunization Scheduler to create a printout of the recommended vaccines and dates for getting your child back on schedule.
