COVID-19 Vaccines Is it safe to administer the COVID-19 vaccine to women who are breastfeeding? There is no data on the safety of COVID-19 vaccines in lactating women, on the effects of mRNA vaccines on the breastfed infant, or on milk production/excretion. However, mRNA vaccines are not thought to be a risk to the breastfeeding infant. People who are breastfeeding and are part of a group recommended to receive a COVID-19 vaccine (e.g., healthcare personnel), may choose to be vaccinated.

CDC guidance for SARS-CoV-2 infection may, or may not, be adopted by state and local health departments to respond to rapidly changing local circumstances. Providers should always check with their local health department to see if the CDC’s guidance on any given topic has been modified (particularly if more restrictive) from the CDC’s recommended guidelines. Follow this link https://www.cdc.gov/publichealthgateway/healthdirectories/index.html for contact information to your state/local health department. If local recommendations vary from those of the CDC, and you are unsure what recommendations to follow, then it is safer to follow the more restrictive guidelines/recommendations.
