Insights
Pregnant and breastfeeding individuals can consider SARS-CoV-2 vaccination. COVID-19 risks during pregnancy likely exceed potential vaccine risks, despite limited specific data.
Area of Science:
- Immunology
- Vaccinology
- Obstetrics & Gynecology
Background:
- The introduction of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in late 2020/early 2021 prompted guidance from professional societies for pregnant and breastfeeding populations.
- A significant challenge for this demographic is the limited data on SARS-CoV-2 vaccine safety, immunogenicity, and efficacy in pregnant and breastfeeding individuals.
Purpose of the Study:
- To provide a balanced perspective on SARS-CoV-2 vaccination for pregnant and breastfeeding individuals.
- To weigh the known risks of coronavirus disease 2019 (COVID-19) in pregnancy against the potential, less-understood risks of SARS-CoV-2 vaccination.
Main Methods:
- This analysis is based on existing data regarding vaccine safety and efficacy in nonpregnant populations.
- Risk-benefit assessment considering the clinical presentation and outcomes of COVID-19 in pregnant individuals.
Main Results:
- SARS-CoV-2 vaccines demonstrate reassuring safety and efficacy profiles in the general, nonpregnant population.
- The known risks associated with COVID-19 during pregnancy are substantial.
Conclusions:
- The potential risks of SARS-CoV-2 vaccines in pregnant and breastfeeding individuals are not yet fully elucidated.
- However, the established risks of COVID-19 during pregnancy likely outweigh the potential risks of vaccination, supporting informed decision-making.
Abstract:
As the first severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines passed UK and US regulatory milestones in late 2020 and early 2021, multiple professional societies offered recommendations to assist pregnant and breastfeeding people as they choose whether to undergo vaccination. Despite such guidance, the lack of data describing vaccine safety, immunogenicity, and efficacy in pregnant and breastfeeding people has made this decision challenging for many. However, even considering the paucity of data, the known risks of coronavirus disease 2019 during pregnancy likely outweigh the not yet fully elucidated risks of SARS-CoV-2 vaccines, which have reassuring safety and efficacy profiles among nonpregnant people.
