Percent of children age 24 months who received recommended vaccines

Measure Overview

Vaccination is an effective way to protect infants and young children from harmful diseases that can cause serious illness or death. Examples of diseases against which children are commonly vaccinated include chickenpox (Varicella), polio, hepatitis A and B, and measles, mumps, and rubella (MMR). Despite the well-documented safety and efficiency of the vaccines, along with the endorsement of child vaccinations by the Centers for Disease Control and Prevention (CDC) and other public health authorities, rates of child vaccination lag in some portions of the United States. Monitoring trends in child vaccination rates can help explain why such gaps exist and inform efforts to improve child vaccination rates in the U.S.

State Health Compare presents annual, state-level child vaccination rates based on findings from the National Immunization Survey (NIS). The NIS collects data on the following child vaccines: MMR, Varicella, influenza, rotavirus, hepatitis A, hepatitis B, DTaP (diphtheria, tetanus, and whooping cough/pertussis), pneumococcal vaccines (PCV), polio, and Hemophilus influenza type b (Hib).
