evidence: Through early May 2021, COVID-19 vaccination coverage among pregnant women within VSD was low; however, coverage increased over the analytic period across all age and racial and ethnic groups. The increase might be attributable to inclusion of pregnancy among the conditions that increase risk for severe COVID-19 and thus for prioritization for early allocation of COVID-19 vaccines,§§ as well as the rollout of vaccines to the entire U.S. population in mid-April. In addition, analyses of emerging data regarding safety of COVID-19 vaccines, specifically mRNA vaccines, have detected no safety signals for pregnant women (10). In early data from three of CDC’s vaccine safety monitoring systems, no safety concerns were identified for vaccinated pregnant women or their infants; additional follow-up is needed, particularly among women vaccinated in the first and second trimesters of pregnancy (10). There are also emerging data suggesting that COVID-19 vaccination during pregnancy can lead to transfer of antibodies through placenta and breast milk, which might confer some immunity to newborns.¶¶
