Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
Number of children aged 2 to 4 years who receive 1 dose of influenza vaccine during the most recent influenza season
Children aged 2 to 4 years at the time of the interview. Only interviews conducted from March through August of the data year are included.
From the 2008 National Health Interview Survey:
[NUMERATOR:]
During the PAST 12 MONTHS, has (Sample child) had a flu shot? A flu shot is usually given in the fall and protects against influenza for the flu season.
This measure tracks the number of children aged 2 to 4 years who receive 1 dose influenza vaccine within the past influenza season.
The Advisory Committee on Immunization Practices (ACIP) recommends two doses of influenza vaccine when needed for children 6 months to 8 years of age. However, the National Health Interview Survey (NHIS) does not ask about more than one dose for children less than 9 years of age, nor does it ask about prior season vaccinations (this would be required to determine if two doses were indicated for the current season).
Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.
