Frequently Asked Questions about Pregnancy and fertility

Yes. Based on data on the safety of COVID-19 vaccines during pregnancy, CDC recommends COVID-19 vaccination for all people who are pregnant, breastfeeding, or trying to get pregnant now or in the future. Data show that pregnant and recently pregnant people are more likely than non-pregnant people to get severely ill if they are infected with COVID-19, and the highly contagious Delta and Omicron variants makes it even more important for eligible people to get vaccinated. 

In addition, the American College of Obstetricians and Gynecologists and other leading maternal health and public health organizations are “strongly urging” all pregnant individuals, and anyone planning to become pregnant, to get vaccinated against COVID-19.

No. There is no evidence to show that getting a vaccine increases the risk of miscarriage.

There has been extensive safety monitoring of the COVID-19 vaccines, including analysis of vaccination during pregnancy. Specifically, studies show that the rate of miscarriage in the first 20 weeks of pregnancy in the general population is about 11-16%, and an analysis of safety monitoring data of people who received an mRNA COVID-19 vaccine showed a similar rate of 13%.In other words, being vaccinated with one of the currently available COVID-19 vaccines does not increase miscarriage risk; rather, it protects against the higher risk of serious illness if you are pregnant and become infected with the virus.

Antibodies made after a pregnant person received an mRNA COVID-19 vaccine have been found in umbilical cord blood, which means that COVID-19 vaccination during pregnancy might help protect babies against COVID-19. Additionally, recent reports have shown that breastfeeding people who have received mRNA COVID-19 vaccines have antibodies in their breast milk, which could help protect their babies. In both of these cases, more data are needed to determine the level of protection these antibodies may provide to the baby and how long that protection would last.
