The Centers for Disease Control and Prevention's recommended vaccine schedule has been in use for 50 years. A child vaccinated by the CDC's tried, tested and true 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 who care for children 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. To learn more about why the vaccine schedule is the way it is, read this American Academy of Pediatrics FAQ sheet: "The Child Immunization Schedule: Why Is It Like That?" (PDF) These experts determine each vaccine's dose timing using two factors. First, it is scheduled for the age when the body's immune system will respond best. Second, it is balanced with the need to provide protection to infants and children at the earliest possible age.
Below are the Centers for Disease Control and Prevention's (CDC) age-appropriate recommended vaccine schedules.
Your child’s health and safety are very important to your child’s doctor. Doctors and healthcare providers consider the recommended schedule ideal for healthy children but there may be exceptions. If you have any questions about the recommended vaccine schedule, talk to your health care provider.
