Health officials recommend COVID-19 vaccines and boosters for people who are pregnant, breastfeeding and trying to become or planning on getting pregnant. The guidance is based on studies that show risks of severe disease are high among the group.
Now, a new study of more than 1,300 pregnant patients reveals how timing of coronavirus vaccination influences antibody levels at the time of delivery.
Researchers found antibodies at birth were highest among fully vaccinated pregnant patients without a history of COVID-19 who received their first Pfizer or Moderna shots during their third trimester. Antibody levels were lowest among those who were vaccinated before they got pregnant or during their first trimester, though researchers say the “difference wasn’t large.”
