Study supports COVID-19 vaccination during pregnancy

Receiving a COVID-19 mRNA vaccine or booster during pregnancy can benefit pregnant people and their newborn infants, according to findings from a federally funded study published in Vaccine. The study looked at 167 pregnant people who received a primary or booster vaccine, which generated antibodies that crossed to the cord blood and likely conferred some protection in their newborns. Participants who received a booster dose had substantially more antibodies in their own blood and in their cord blood, suggesting that boosting increased their newborns’ immune defenses against COVID-19.
