Objectives – Our study aims to estimate influenza vaccination coverage (VC) among pregnant women and to explore the associated socioeconomic determinants. Secondary objectives include estimating the proportion of pregnant women who report having been offered an influenza vaccination by a doctor or midwife, as well as the proportion of pregnant women who followed this recommendation and the associated determinants. Method – Data were collected during the 2021 Baromètre de Santé publique France survey. Women with a child under 3 years of age were asked about influenza vaccination during their most recent pregnancy. Determinants were analyzed using multivariate Poisson regressions. Results – A total of 731 women were surveyed. The influenza vaccination coverage among pregnant women between 2019 and 2021 was estimated at 21.1% (95% confidence interval: [17.9–24.8]). It ranged from 21.4% [16.4–27.4] for those with a child under 1 year of age to 30.6% [23.8–38.4] for those with a child aged 1 year who were predominantly pregnant after the emergence of SARS-CoV-2, and 12.4% [8.4–17.8] for those with a child aged 2 years who were predominantly pregnant before the pandemic. It was significantly higher among women with high incomes (31.8% [24.7–39.8]) and those in the workforce (26.2% [22.0–30.9]) than among those who were unemployed (10.7% [6.6–16.6]), and those living in metropolitan areas with more than 200,000 inhabitants or in the Paris metropolitan area (25.8% [20.6–31.8]). Vaccination was offered by a doctor or midwife to 36.9% [32.8–41.1] of women and less frequently to low-income women, those who were unemployed, or those not in the workforce. Finally, vaccination was offered more frequently after the emergence of SARS-CoV-2. Conclusion – Influenza vaccination coverage among pregnant women remains very low in France relative to the 75% vaccination target. Vaccination coverage, as well as the offer of vaccination, is marked by social health inequalities.
