Uptake of the COVID-19 vaccine in pregnancy

Abstract

Coronavirus disease 2019 (COVID-19) has rapidly become a global pandemic with a devastating morbidity and mortality. Pregnant women seem to be at increased susceptibility to have a severe disease and suffer adverse pregnancy outcomes. The only solution to mitigate this pandemic is prophylaxis by mass vaccination. We report a review based on current literature about the evidence available on efficacy and safety of anti-COVID-19 vaccines in pregnancy to aid women decide whether to vaccinate or not, while being pregnant or lactating. Studies so far did not find concerning maternal or fetal outcomes and show a similar efficiency of mRNA vaccines as in non-pregnant population. Moreover, anti-SARS-CoV-2 antibodies resulted from the vaccination seem to be transferred to the newborn through the placenta or the breastmilk building up the neonatal immunity. However, the exclusion from clinical trials created a great deficiency of evidence regarding the vaccination in this high-risk population resulting in their reluctance.
