What do we know about the safety of COVID-19 vaccine mRNA in breast milk?
The mRNA inCOVID-19 mRNA vaccines can enter breast milk. However, research only detected small amounts of it, which were mostly degraded and non-functional form. COVID-19 vaccines are beneficial to pregnant women because they are particularly at risk of severe disease and poorer pregnancy outcomes. Furthermore, breast milk from lactating women contains antibodies able to neutralize the COVID-19 virus, meaning that vaccinated women can pass on some protection against COVID-19 to their babies.
