Pregnancy & Flu

CDC estimates annual influenza vaccination coverage for the United States by utilizing data from several nationally representative surveys: the Behavioral Risk Factor Surveillance System (BRFSS), the National Health Interview Survey (NHIS), and the National Immunization Survey-Flu. (NIS-Flu). Internet panel surveys of adultshealth care personnel, and pregnant women are also used. CDC's FluVaxView webpage provides vaccination coverage estimates for current and previous influenza seasons, reports, interactive figures, and data tables.

2017-2018 Flu Vaccination Rate Estimates in Pregnant Women 

As of early November 2017, flu vaccination coverage among pregnant women before and during pregnancy was 35.6%, approximately 11 percent points lower compared with 2016-17 early-season vaccination coverage (46.6%). 

  • Most pregnant women (97.9%) reported visiting a doctor or other medical professional at least once before or during pregnancy since July 1, 2017. Among these women, 58.7% reported receiving a recommendation for and offer of flu vaccination from a doctor or other medical professional, 15.6% received only a recommendation for and no offer of flu vaccination, and 25.7% did not receive a recommendation for or an offer of flu vaccination, similar to the proportions from November 2016 (52.4%, 26.1% and 5.7%, respectively).

  • A change in survey methodology in November 2017 allowed more women to participate in the survey using a smartphone or other handheld device (73.4% compared with 16.5% in November 2016). This shifted the characteristics of the survey sample, so comparisons of vaccination coverage from November 2017 to previous survey years cannot be made.

2016-2017 Flu Vaccination Rate Estimates in Pregnant Women 

As of early November 2016, flu vaccination coverage among pregnant women before and during pregnancy was 46.6%, approximately 6 percentage points higher compared with 2015-16 early-season vaccination coverage (40.2%). 

  • In the previous two flu seasons, vaccination coverage increased by approximately 7-10 percentage points from the early season to the end of the season. 

  • Most women (98.7%) reported visiting a doctor or other medical professional at least once since July 1, 2016. Among these women, 60.2% reported receiving a recommendation for and offer of vaccination from a doctor or other medical professional, 14.2% received only a recommendation for and no offer of flu vaccination, and 24.3% did not receive a recommendation or an offer for flu vaccination, similar to the proportions from November 2015 (61.6%, 15.0% and 23.4%, respectively).

  • Women who reported receiving a provider recommendation for and offer of vaccination were more than twice as likely to be vaccinated compared with women who received only a recommendation but no offer of vaccination (65.7% vs. 29.8%) and six times more likely to be vaccinated compared with women who did not receive a recommendation or an offer for vaccination (65.7% vs 11.1%).
