Overview

Cohort study reveals suboptimal influenza vaccination coverage among privately insured pregnant women, highlighting persistent timing gaps after October.

Key Points

  • To assess national trends, timing patterns, and maternal characteristics associated with influenza vaccination coverage among privately insured pregnant women.
  • Analyzed 2010–2018 MarketScan healthcare claims for 1,286,749 privately insured pregnant women aged 15–49 years in the United States.
  • Assessed vaccination timing across trimesters and delivery months, estimating predictors of uptake via multivariate log-binomial and Cox proportional hazards regression models.
  • In-plan influenza vaccination coverage prior to delivery increased from 22.0% during the 2010–2011 season to 33.2% during the 2017–2018 season.
  • Approximately two-thirds of vaccinated women received the vaccine in September or October, with vaccination rates plateauing sharply after October for women delivering between September and May.
  • Higher vaccination uptake was significantly associated with maternal age 31–40 years, metropolitan residence, living outside the South, high-deductible health plan enrollment, and delivery between November and January.
