Immunizations Overview

Immunizations are one of the greatest public health achievements, preventing tens of thousands of deaths, millions of cases of disease, and saving billions of dollars per decade. Immunizations are a safe, effective way to protect children from disease, including some cancers, as well as hospitalization, disability, and death. It is especially important during a pandemic or other public health emergency to maintain routine immunizations to prevent further outbreaks.

Pediatricians play a crucial role in immunizing children and are a trusted source for vaccine information. Vaccine conversations with parents should begin as early as possible – at prenatal visits/interviews ideally – as families often make immunization decisions during pregnancy through the first 2 months of baby’s life.

AAP Recommendations

The American Academy of Pediatrics strongly recommends immunizations as the safest and most cost-effective way of preventing disease, disability, and death. The AAP calls for the on-time, routine immunization of all children and adolescents according to its policy, Recommended Immunization Schedules for Children and Adolescents Aged 18 Years or Younger, United States, 2022.

The AAP Red Book serves as policy of the AAP and is written by the AAP Committee on Infectious Diseases. Chapter 1 of the Red Book focuses on Immunizations. Chapter 3 includes Summaries of Infectious Diseases, including those prevented by routine immunization.

The AAP supports regulations and laws requiring immunizations to attend child care and school, with exemptions for specific immunizations only when medically contraindicated for an individual child. The AAP views nonmedical exemptions to school-required immunizations as inappropriate for individual, public health, and ethical reasons and advocates for their elimination. More is available in the policy statement, Medical Versus Nonmedical Immunization Exemptions for Child Care and School Attendance.

To support routine and on-time vaccination of adolescents, the AAP has issued the clinical report, The Need to Optimize Adolescent Immunization, which reminds pediatricians that every visit is an opportunity to vaccinate.

Other AAP Policies and Clinical Reports include the following:

CDC Childhood Immunization Coverage

The National Immunization Surveys (NIS) are a group of phone surveys used to monitor vaccination coverage among children 19-35 months and teens 13-17 years. You can learn about data collected in the most recent NIS.


In August 2021, the immunization information on was revised. We seek your feedback on the new organization and ease of use for the immunization content please consider filling out this brief survey. We estimate it will take 2 minutes to complete.
