Vaccination Against COVID-19 in Pregnant and Lactating Women in Belgium

This study will investigate whether pregnant and lactating women can develop similar protective immunity as non-pregnant women against Coronavirus Infectious Disease 2019 (COVID-19) upon vaccination, without safety issues. Immunogenicity and safety of all currently licensed COVID-19 vaccines that are administered to pregnant and lactating women in Belgium will be studied.
