Flu & Pregnancy 

2015-2016 Flu Vaccination Rate Estimates in Pregnant Women 

As of early November 2015, flu vaccination coverage before and during pregnancy among pregnant women was 40.2%, similar to 2013-14 early season vaccination coverage (43.5%)

  • Non-Hispanic black pregnant women had the lowest flu vaccination coverage (32.9%) compared to the other three racial/ethnic groups (non-Hispanic white: 39.9%, Hispanic: 44.6%, and non-Hispanic other: 46.4%). 

  • Most women (97.8%) reported visiting a doctor or other medical professional at least once since July 1, 2015. Among these women, 61.6% reported receiving a recommendation for and offer of vaccination from a doctor or other medical professional, 15.0% received only a recommendation for and no offer of vaccination, and 23.4% did not receive a recommendation for flu vaccination which were similar to the proportions in November 2014 (59.5%, 15.3% and 25.1%, respectively).

  • Women who received a recommendation for and an offer of vaccination from a doctor or other medical professional were more likely to be vaccinated.

    • They were almost three times more likely to be vaccinated as women who received only a recommendation for vaccination but no offer of vaccination (58.8% vs. 20.1%) and eight times more likely to be vaccinated as women who did not receive a recommendation for vaccination (58.8% vs.7.1%)

    • Vaccination coverage among those who received provider recommendation and offer for vaccination (58.8%) or among those who received recommendation only (20.1%) were lower compared to November 2014 (65.2% and 25.5%, respectively).
