Updates as of December 20, 2021:
If you are pregnant or planning to become pregnant, consider the guidance below. You can also talk to your healthcare provider to help you in your decision whether to get the COVID-19 vaccine.
Pregnant and lactating people should choose between the Pfizer-BioNTech and Moderna COVID-19 vaccines to protect them and may consider discussing with their usual healthcare provider. The Moderna COVID-19 vaccine is 2-doses, spaced 4 weeks apart. The Pfizer-BioNTech COVID-19 vaccine is 2 doses, spaced 3 weeks apart. People who are pregnant may also receive a COVID-19 vaccine booster shot either six months after a two-dose Moderna or Pfizer series or two months after a one-dose Johnson & Johnson series. If you received a Johnson & Johnson dose, strongly consider getting a Pfizer or Moderna booster shot. These vaccines use a small, harmless piece of the virus that triggers an immune response. The immune system can then recognize the virus, should it infect the body, and make antibodies to protect against COVID-19.
Pregnant people or recently pregnant (within 42 days postpartum) are at higher risk for getting very sick with COVID-19, this includes the risk of being hospitalized, being in the intensive care unit or requiring help breathing through mechanical ventilation) compared to people who are not pregnant and get sick with COVID-19. In addition, pregnant people are at increased risk of pre-term birth (delivering a baby before 37 weeks).
The Centers for Disease Control and Prevention (CDC), The American College of Obstetricians and Gynecologists (ACOG) and the Society for Maternal-Fetal Medicine recommend the COVID-19 vaccine for all people 5 years and older, including people who are pregnant, breastfeeding, trying to get pregnant now, or might become pregnant in the future.
CDC followed more than 35,000 pregnant people who were vaccinated with the COVID-19 vaccine. No safety concerns were identified. The vaccines provided in the U.S. do not use the live virus that causes COVID-19. This means that a COVID-19 vaccine cannot infect you or your baby with COVID-19.
The Moderna and Pfizer COVID-19 vaccines are recommended for pregnant people because of the protection they provide against COVID-19. The vaccine works by triggering an immune response in the body, causing the body to produce protective antibodies.
Breastfeeding people can receive the COVID-19 vaccine.
COVID-19 vaccines are safe for breastfeeding people and their babies. Recent reports have shown that breastfeeding people who have received COVID-19 mRNA vaccines (Moderna and Pfizer) have antibodies in their breastmilk, which could help protect their babies.
If you are pregnant and decide to get vaccinated, follow the CDC fully vaccinated guidance and the Guidance for the Use of Face Coverings to learn more about what you can do once you are fully vaccinated*.
