The objective of this stuyd was to examine the risk of adverse pregnancy outcomes after vaccination against SARS-CoV-2 during pregnancy. Findings suggets that in this population-based study conducted in Sweden and Norway, vaccination against SARS-CoV-2 during pregnancy, compared with no SARS-CoV-2 vaccination during pregnancy, was not significantly associated with an increased risk of adverse pregnancy outcomes. The majority of the vaccinations were with mRNA vaccines during the second and third trimesters of pregnancy, which should be considered in interpreting the findings.
