MMR Vaccine in Lactation

Breastfeeding Research April 1, 2025

The MMR vaccine is the best known way to prevent severe cases of measles. Measles is contagious to both vaccinated and unvaccinated individuals. Evidence supports that those who do receive the MMR vaccine are less likely to develop severe illness and complications associated with the measles virus. The MMR vaccine is compatible with breastfeeding. Research is currently being done to determine if antibodies increase in milk that may be beneficial to breastfed infants who are too young to receive the MMR vaccine themselves.

Research

Every year, the InfantRisk Center publishes studies on the transfer of various drugs into breast milk. We invite you to review these studies and consider participating in one of them. Participation is simple: you will need to collect samples of your breast milk at regular intervals, freeze them, and send them to our laboratories using prepaid overnight mailing. Your involvement will greatly contribute to our research and help ensure the safety of medications for breastfeeding mothers.
