Temporal trends and determinants of COVID-19 vaccine coverage and series initiation during pregnancy in Ontario, Canada, December 2020 to December 2021: A population-based retrospective cohort study.

ABSTRACT:

Background

Population-based COVID-19 vaccine coverage estimates among pregnant individuals are limited.
