There are as yet no studies which confirm exactly how long the antibody protection lasts in infants whose mother had COVID-19 and continues to breastfeed. It has been found that the antibodies in mothers who had COVID-19 seem to remain present in breast milk for at least around 10 months post-infection.  A study looking at breastfeeding mothers who had received the COVID-19 vaccine suggests that they may pass protective antibodies to their babies through breast milk for at least 80 days following vaccination. For safe storage of expressed breast milk at home please see our guidelines.
