    1. Yes
    2. No
Data Collection Frequency: 
Annual
Methodology Notes: 

    Questions used to determine pregnancy status during August through March of each influenza season were added to the NHIS in 2012. To assess influenza vaccination coverage for each season, reported coverage is restricted to women interviewed during August through July, and vaccinated during July through March, using the Kaplan-Meier survival analysis procedure. For women not pregnant at time of interview, follow-up time was estimated by assuming that the pregnancy ended at the mid-point between August 1 and the date of interview. Vaccination month was imputed when the woman was reported to have been vaccinated before or during pregnancy but was missing the month and/or year of vaccination. Weighted data are used to produce national vaccination coverage estimates. Point estimates and 95% confidence intervals (CIs) are calculated by using statistical software to account for the complex sample design.

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, Objective IID-12.10 was revised to objective IID-12.14 and the objective reverted to developmental status. Potential data sources included the National Health Interview Survey (NHIS), CDC/NCHS; Behavioral Risk Factor Surveillance System (BRFSS), CDC/NCCDPHP; Pregnancy Risk Assessment Monitoring System (PRAMS), CDC/NCCDPHP; and Internet Panel Survey, CDC/NCIRD. In 2016, objective IID-12.14 reverted to measurable status with the NHIS as the data source.
