The Centers for Disease Control and Prevention's (CDC) recommended vaccine schedule has been in use for 50 years. A child vaccinated according to the CDC’s vaccine schedule will have immunity to over 14 diseases by the age of two.
Each year, the vaccine schedule is determined by an expert panel of top disease experts and doctors based on the most recent scientific data and is approved by the American Academy of Pediatrics, the Centers for Disease Control and Prevention, and the American Academy of Family Physicians.
These experts determine each vaccine's dose timing using two factors:
Vaccines are important, and not vaccinating on time leaves your child vulnerable to disease. It is important to vaccinate babies as soon as it’s safe, because infants are especially vulnerable to infectious diseases. Not vaccinating according to the recommended schedule also allows for the spread of disease to others in your community, some of whom cannot be vaccinated -- such as infants and people with certain illnesses -- and are at increased risk for vaccine-preventable diseases.
The recommended immunization schedule is designed to protect infants and children early in life, when they are most vulnerable and before they are exposed to potentially life-threatening diseases.
Check the schedule for the age or age range when each vaccine or series of shots is recommended for infants, children, or teens. Your child’s health and safety are very important! If you have any questions about the recommended vaccine schedule, talk to your health care provider.
