People Who Are Breastfeeding
Clinical trials for the COVID-19 vaccines currently authorized for use under an Emergency Use Authorization in the United States did not include people who are breastfeeding. Because the vaccines have not been studied on lactating people, there are no data available on the:
Safety of COVID-19 vaccines in lactating people
Effects of vaccination on the breastfed baby
Effects on milk production or excretion
Based on how these vaccines work in the body, COVID-19 vaccines are thought not to be a risk to lactating people or their breastfeeding babies. Therefore, lactating people can receive a COVID-19 vaccine. Recent reports have shown that breastfeeding people who have received COVID-19 mRNA vaccines have antibodies in their breastmilk, which could help protect their babies. More data are needed to determine what protection these antibodies may provide to the baby.
People Who Would Like to Have a Baby
If trying to get pregnant now or in the future, would-be parents can receive a COVID-19 vaccine. There is currently no evidence that any vaccines, including COVID-19 vaccines, cause female or male fertility problems—problems getting pregnant. CDC does not recommend routine pregnancy testing before COVID-19 vaccination. If you are trying to become pregnant, you do not need to avoid pregnancy after receiving a COVID-19 vaccine. Like with all vaccines, scientists are studying COVID-19 vaccines carefully for side effects now and will report findings as they become available.
Getting Vaccinated is a Personal Choice
If you are pregnant, you can receive a COVID-19 vaccine. You may want to have a conversation with your healthcare provider to help you decide whether to receive 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 COVID-19 vaccines:
How well they work to develop protection in the body
Known side effects of vaccination
Limited, but growing, information on the safety of COVID-19 vaccination during pregnancy
How vaccination might pass antibodies to the fetus. Recent reports have shown that people who have received COVID-19 mRNA vaccines during pregnancy (mostly during their third trimester) have passed antibodies to their fetuses, which could help protect them after birth.
