Information about COVID-19 Vaccines for People who Are Pregnant or Breastfeeding
Getting vaccinated is a personal choice. Any of the currently authorized COVID-19 vaccines can be offered to people who are pregnant or breastfeeding. If you have questions about getting vaccinated, a conversation with your healthcare provider might help, but is not required.
Pregnant people are at increased risk for severe illness from COVID-19
Although the overall risk of severe illness is low, pregnant people are at an increased risk for severe illness from COVID-19 when compared to non-pregnant people. Severe illness includes illness that results in intensive care admission, mechanical ventilation, or death. Additionally, pregnant people with COVID-19 might be at increased risk of adverse pregnancy outcomes, such as preterm birth, compared with pregnant women without COVID-19.
Limited data are available about the safety of COVID-19 vaccines for people who are pregnant
Based on how these vaccines work in the body, experts believe they are unlikely to pose a specific risk for people who are pregnant. However, there are currently limited data on the safety of COVID-19 vaccines in pregnant people
Clinical trials that look at the safety and how well the COVID-19 vaccines work in pregnant people are underway or planned. Vaccine manufacturers are also monitoring data from people in the clinical trials who received vaccine and became pregnant.
Studies in animals receiving a Moderna, Pfizer-BioNTech, or Johnson & Johnson’s Janssen (J&J/Janssen) COVID-19 vaccine before or during pregnancy found no safety concerns.
CDC and the Federal Drug Administration (FDA) have safety monitoring systems in place to gather information about vaccination during pregnancy and will closely monitor that information. Most of the pregnancies in these systems are ongoing, so we don’t yet have information on the outcomes of these pregnancies. We need to continue to follow pregnancies long-term to understand effects on pregnancy and infants.
The Moderna and Pfizer-BioNTech vaccines are mRNA vaccines that do not contain the live virus that causes COVID-19 and, therefore, cannot give someone COVID-19. Additionally, mRNA vaccines do not interact with a person’s DNA or cause genetic changes because the mRNA does not enter the nucleus of the cell, which is where our DNA is kept. Learn more about how COVID-19 mRNA vaccines work.
The J&J/Janssen COVID-19 Vaccine is a viral vector vaccine, meaning it uses a modified version of a different virus (the vector) to deliver important instructions to our cells. Viral vector technology has been used by Janssen for other vaccine development programs. Vaccines that use the same viral vector have been given to pregnant people in all trimesters of pregnancy, including in a large-scale Ebola vaccination trial. No adverse pregnancy-related outcomes, including adverse outcomes that affected the infant, were associated with vaccination in these trials. Learn more about how viral vector vaccines work.
If you are pregnant and receive a COVID-19 vaccine, consider participating in the v-safe pregnancy registry
If you are pregnant and have received a COVID-19 vaccine, we encourage you to enroll in v-safe. V-safe is CDC’s smartphone-based tool that uses text messaging and web surveys to provide personalized health check-ins after vaccination. A v-safe pregnancy registry has been established to gather information on the health of pregnant people who have received a COVID-19 vaccine. If people enrolled in v-safe report that they were pregnant at the time of vaccination or after vaccination, the registry staff might contact them to learn more. Participation is voluntary, and participants may opt out at any time.
Getting vaccinated is a personal choice
If you are pregnant, you may choose to receive a COVID-19 vaccine. You may want to have a conversation with your healthcare provider to help you decide whether to get vaccinated with a vaccine that has been authorized for use under Emergency Use Authorization. While a conversation with your healthcare provider may be helpful, it is not required prior to vaccination. Key considerations you can discuss with your healthcare provider include:
How likely you are to being exposed to the virus that causes COVID-19
Risks of COVID-19 to you and the potential risks to your fetus or infant
What is known about the vaccine:
how well it works to develop protection in the body
known side effects of the vaccine
limited data on the safety of COVID-19 during pregnancy, because it was not studied among pregnant people
