As of December 1, 2020, nearly 64 million people have been infected with the severe acute respiratory syndrome coronavirus 2 worldwide with nearly 1.5 million global deaths. The impact of this virus has continued to overwhelm hospital infrastructure and demanded remodeling of healthcare systems. With rising concerns for a third, and possibly the largest, wave of individuals infected with the virus, national leaders are continuing to seek avenues by which we can further limit disease transmission and prevent infection with the use of vaccination. To our knowledge, no clinical trial evaluating vaccines to prevent coronavirus disease 2019 has included pregnant women. In December 2020, it was anticipated that the Food and Drug Administration will approve at least 1 or 2 mRNA-based coronavirus disease 2019 vaccine under the Emergency Use Authorization based on phase 3 clinical trial efficacy data. Both Pfizer and Moderna have manufactured mRNA-based vaccines with 95% and 94.1% efficacy against the severe acute respiratory syndrome coronavirus 2. AstraZeneca has manufactured a vaccine using a viral vector demonstrating early efficacy as well, and this next-generation platform has previously been utilized with the Ebola vaccine and safely administered during pregnancy with an acceptable safety profile. Approval of these vaccines will have a tremendous impact on the ongoing pandemic, yet there remains a lack of data for use of coronavirus disease 2019 vaccine in pregnant women. In this article, we seek to discuss the available data regarding treatment and prevention of coronavirus disease 2019 in pregnancy and address the growing questions regarding how best to approach vaccine access and administration in the pregnant population.
