Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
Number of pregnant women aged 18 to 44 years who report being pregnant at time of interview, and received an influenza vaccination from September through February
Number of pregnant women aged 18 to 44 years who report being pregnant at time of interview, and who were interviewed from December of the first data year through April of the second data year
From the 2008 National Health Interview Survey:
[NUMERATOR:]
During the PAST 12 MONTHS, have you had a flu shot? A flu shot is usually given in the fall and protects against influenza for the flu season. During what month and year did you receive your most recent flu shot?
[NUMERATOR AND DENOMINATOR:]
Are you currently pregnant?
The National Health Interview Survey (NHIS) asks about current pregnancy status, so this measure will exclude some women who were pregnant during the September through February vaccination period (e.g., pregnant in December, delivered in February, and interviewed in April), and include some women who were not pregnant during the vaccination period (e.g., became pregnant in February and interviewed in April). Pregnant women interviewed during the vaccination period may have received an influenza vaccination while pregnant after the date of their interview.
Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.
