When is the Best Time to Immunize My Child?

The CDC’s Advisory Committee on Immunization Practices (ACIP) develops the Recommended Immunization Schedules for Children, Teens and Adults. The CDC’s childhood immunization schedule is the ONLY vaccination schedule for children that is rigorously tested for safety and effectiveness. Therefore, it is very important to follow it.

The vaccines are carefully timed to provide protection to children when they are most vulnerable to diseases, and when the vaccines will produce the strongest response from the child’s immune system. Some parents are concerned that their children are too young for the recommended vaccinations, but it is important to understand that if a baby is not too young to get the disease, he or she is not too young to get the vaccine. No “non standard” schedules have ever been tested for their safety and effectiveness.

The ACIP is comprised of medical and public health experts. The Committee reports to the CDC three times a year to make recommendations for new vaccines and to make changes to currently recommended vaccines based on the latest science and research. The Committee conducts extensive research on the safety and effectiveness of each vaccine prior to recommending its use for the public.
