This measure assesses the percentage of children who became 2 years old during the measurement year and who had received two influenza (flu) vaccines on or before 2 years of age.

This measure follows the CDC Advisory Committee on Immunization Practices (ACIP) guidelines for immunizations.

A basic method for prevention of illness is immunization. Childhood immunizations help prevent serious illnesses such as polio, tetanus, and hepatitis. Vaccines are a proven way to help a child stay healthy and avoid the potentially harmful effects of childhood diseases like the mumps and measles. Even preventing "mild" diseases saves hundreds of lost school days and work days, and millions of dollars.
