A recent study published in JAMA Network Open by HealthPartners Institute has revealed that administering monovalent COVID-19 booster vaccinations to pregnant individuals before 20 weeks’ gestation does not increase the risk of miscarriage. This study analyzed data from over 100,000 pregnancies from eight different health systems and found that receiving a booster vaccination was not associated with any increased risk of miscarriage. These findings are significant and add to the growing understanding of the safety of COVID-19 booster vaccinations for pregnant individuals.
In addition, another study conducted by HealthPartners Institute and published in Obstetrics & Gynecology has also shown that receiving a booster vaccination at any point during pregnancy did not increase the risk of serious adverse events. Both of these studies utilized data from the Vaccine Safety Datalink, and they concluded that COVID-19 vaccinations in pregnancy are safe. This is an important finding, as it provides reassurance to pregnant individuals who may be considering getting a COVID-19 booster vaccination.
It is worth noting that future studies will be conducted to evaluate the safety of the bivalent booster. However, for now, these studies have shown that pregnant individuals can safely receive a monovalent COVID-19 booster vaccination before 20 weeks’ gestation without any increased risk of miscarriage or serious adverse events.
