evidence: COVID-19 Vaccine and Pregnancy COVID-19 vaccines approved by the Food and Drug Administration (FDA) are safe and recommended for people who are pregnant or lactating, as well as for those who are intending to become pregnant. People who are pregnant or were recently pregnant are at a greater risk for severe COVID-19. Having a severe case of COVID-19 while pregnant is linked to a higher risk of preterm birth and stillbirth and might increase the risk of other pregnancy complications. For these reasons, COVID-19 vaccination is recommended for people who are pregnant, intending to become pregnant or were recently pregnant.
