Vaccination coverage under a magnifying glass with syring

The VaxView websites provide vaccination coverage data for all ages. Monitoring coverage for recommended vaccinations across the country helps CDC assess how well local areas, states, and the nation are protected from vaccine-preventable diseases.

What is Vaccination Coverage and Why is it Important?

Vaccination coverage is the estimated percent of people who have received specific vaccines. Health departments all over the United States monitor vaccination coverage to understand how well communities are protected from vaccine-preventable diseases. Vaccination coverage information is used to identify areas and groups with lower vaccination coverage so public health departments, health care partners, and schools can take action to help improve vaccination coverage and protect everyone from vaccine-preventable diseases.

ChildVaxView

View data on vaccination coverage for children 19 through 35 months old. Data are available for the vaccines routinely recommended for young children by the Advisory Committee on Immunization Practices (ACIP). These vaccines to protect young children from potentially serious diseases like measles and whooping cough. Data are available for local areas, states, HHS regions, and the nation from the National Immunization Survey (NIS). Sociodemographic data from the NIS are also available.

SchoolVaxView

Each school year, states and local areas report the estimated number of children attending kindergarten who have received vaccinations recommended or required by their state or who have received an exemption to one or more required vaccinations. View data reported by states, as well as information about state school vaccination requirements.

TeenVaxView

View data on adolescent vaccination coverage for vaccines routinely recommended by the ACIP for preteens and teens. These include HPV, Td or Tdap, MenACWY, and other vaccines. Data are available for local areas, states, HHS regions, and the nation from the National Immunization Survey-Teen (NIS-Teen). Sociodemographic data from the NIS-Teen are also available.

AdultVaxView

View data on vaccination coverage for adults 18 years and older. CDC routinely assesses how many adults received pneumococcal, Td/Tdap, shingles (herpes zoster), and other vaccinations. Data are available for local areas, states, HHS regions, and the nation from the Behavioral Risk Factor Surveillance System (BRFSS) and the Long-Term Care Minimum Data Set (MDS). Reports using data from the National Health Interview Survey (NHIS) and other data sets are also available.

FluVaxView

View flu vaccination data for people 6 months and older as recommended by the Advisory Committee on Immunization Practices (ACIP), for people at increased risk for flu such as nursing home residents and pregnant women, and for health care personnel, who could transmit flu to those at increased risk. Data are available for local areas, states, HHS regions, and the nation from the National Immunization Survey-Flu (NIS-Flu), the Behavioral Risk Factor Surveillance System (BRFSS), the Long-Term Care Minimum Data Set (MDS), and other data sets.

How does CDC track vaccination coverage?

CDC keeps track of the vaccination rates for the vaccines that are recommended by the Advisory Committee on Immunization Practices (ACIP). This group of medical and public health experts develops recommendations on the use of vaccines to prevent vaccine-preventable diseases (VPDs) that occur in infants, children, adolescents, and adults. CDC uses several surveys to measure the vaccination rates for vaccines recommended for different groups, including:

  • The National Immunization Survey (NIS) for vaccinations given through 35 months
  • School Vaccination Assessment Reports for vaccinations required to enroll in kindergarten
  • The NIS-Teen for vaccinations given to preteens and teens
  • The Behavioral Risk Factor Surveillance System (BRFSS) for vaccinations given to adults, including flu vaccinations
  • The NIS-Flu for flu vaccinations given to 6 months through 17 years
