COVID-19 vaccines and breastfeeding

The COVID-19 vaccines are new. We are still learning about the safety of them while breastfeeding. The vaccines were not tested on breastfeeding women.

But the information we have so far shows that all the COVID-19 vaccines can be given to breastfeeding women. They do not have any effect on breastfed babies. There is no known reason to avoid breastfeeding if you are vaccinated.

If you are breastfeeding, you should get your COVID-19 vaccine when it is offered to you.

Breastfeeding after your COVID-19 vaccine

You can breastfeed after being vaccinated.

If very small parts of the vaccine get into your breast milk, they will be digested in your baby’s stomach. Your vaccine is rapidly broken down in the body and cannot become part of your baby’s DNA. It cannot infect your baby with COVID-19.

If you were vaccinated while pregnant, antibodies against COVID-19 may pass into the breast milk and give some protection to your baby.
