Maternal SARS-CoV-2 vaccination and infant protection against SARS-CoV-2 during the first six months of life
Abstract
This study investigates the impact of maternal COVID-19 vaccination during pregnancy on infant infection during the first six months of life. Using data from California, USA, the authors find that protection against infection during the period of Delta dominance was high, but that it declined during the Omicron period.
