Pertussis vaccination coverage in women at two months postpartum and associated factors in France, National Perinatal Survey 2021.

Background: Pertussis vaccination in young mothers aims to protect neonates through cocooning. We estimated pertussis vaccination coverage (VC) in women at two months postpartum in France in 2021, and the proportion of women who got vaccinated in the first two months postpartum; associated determinants were studied.

Methods: We used data from the 2021 National Perinatal Surveys conducted in metropolitan France (ENP 2021) and French overseas territories (ENP-DROM 2021).
