Data Collection Frequency: 
Annual
Methodology Notes: 

    In the 2010-11 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 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 adult 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 objectives 14-29a, 14-29c, and 14-29e, which tracked influenza vaccination coverage in noninstitutionalized persons aged 65 and over (14-29a), high risk noninstitutionalized persons aged 18 to 64 years (14-29c) and institutionalized persons (14-29e). These Healthy People 2010 objectives were revised to include Healthy People 2020 objectives which tracked influenza vaccination coverage among noninstitutionalized persons aged 18 to 64 years (IID-12.5), noninstitutionalized high-risk persons aged 18 to 64 years (IID-12.6), noninstitutionalized persons aged 65 years and over (IID-12.7).

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-12.5 through 12.8, assessing seasonal influenza vaccination coverage among adults were consolidated into objective IID-12.12. The age and risk groups of the individual objectives were combined to cover all persons aged 18 years and over. The annual time period was revised from calendar year to influenza season. In 2015, objective IID-12.12 began reporting influenza vaccine coverage estimates for adults in long-term or nursing homes for the 2013 data year. These estimates are from the Minimum Data Set (MDS), CMS. Data for all other population lines are from the National Health Interview Survey (NHIS), CDC/NCHS.
