IID-12.11 Data Details

Expand All

IID-12.11 Increase the percentage of children aged 6 months through 17 years who are vaccinated annually against seasonal influenza

About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

Data Source: 
National Health Interview Survey
Changed Since the Healthy People 2020 Launch: 
Baseline (Year): 
46.9 (2010–11)
Target-Setting Method: 
Maintain consistency with national programs, regulations, policies, and laws.
Target-Setting Method Justification: 
This proposed change to the influenza vaccination coverage measures better reflects the universal vaccination recommendation as well as NCIRD’s work to meet our national targets and goals. We are proposing targets for the general population groups that are still ambitious (given current coverage) but are still achievable, given the time-limited influenza vaccination season, as well as the combined age categories and varying access to the specific populations rolled up into these new, more general, age categories.

Number of persons aged 6 months through 17 years reported to be vaccinated with at least one dose of influenza vaccine within the past influenza season


Number of persons aged 6 months through 17 years as of November 1 of the influenza season

Comparable Healthy People 2010 Objective: 
Adapted from HP2010 objective
Questions Used to Obtain the National Baseline Data: 

    From the 2010 National Health Interview Survey:


    DURING THE PAST 12 MONTHS, has [sample child] had a flu vaccination? This vaccine is usually given in the fall and protects against influenza for the flu season.

    1. Yes
    2. No

    During what month and year did [sample child] receive his or her most recent flu vaccine?

    1. January
    2. February
    3. March
    4. April
    5. May
    6. June
    7. July
    8. August
    9. September
    10. October
    11. November
    12. December

    Enter year of most recent flu vaccine.

Data Collection Frequency: 
Methodology Notes: 

    In the 2010-2011 season, the Advisory Committee for Immunization Practices (ACIP) recommended that all persons aged 6 months and over receive the influenza vaccine. To better assess influenza vaccination coverage (1 or more doses) for each season, we reported coverage restricted to individuals interviewed during September through June, and vaccinated during August through May, using the Kaplan-Meier survival analysis procedure. Vaccination month was imputed when the child was reported to have been vaccinated but was missing the month and/or year of vaccination.

Changes Between HP2010 and HP2020: 
This objective differs from Healthy People 2010 objective 14-22h, which was intended to assess influenza vaccination of children aged 6 to 23 months. The objective was developmental during Healthy People 2010. It became measurable as of the Healthy People 2020 launch and was revised to include four Healthy People 2020 objectives: IID-12.1 (children aged 6 years to 23 months), IID-12.2 (children aged 2 to 4 years), IID-12.3 (children aged 5 to 12 years), and IID-12.4 (children aged 13 to 17 years).

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch: 
In 2013, objectives IID-12.1 through 12.4 assessing seasonal influenza vaccine coverage among children were consolidated into objective IID-12.11. The age groups of the individual objectives were combined to cover children aged 6 months through 17 years. The data source was changed from the National Immunization Survey to the National Health Interview Survey. The annual time period was revised from calendar year to influenza season.
