Information for using COVID-19 vaccinations in breastfeeding women

Vaccination and breastfeeding

Women may receive COVID-19 vaccines and continue to breastfeed.


As there is no known risk associated with giving non-live vaccines during breastfeeding the Joint Committee on Vaccination and Immunisation (JCVI) advises that breastfeeding women may be offered vaccination with COVID-19 vaccines.

The UK Health Security Agency (UKHSA—formerly known as PHE) Immunisation Against Infectious Disease (the Green Book) confirms that emerging safety data is reassuring and protective antibodies have been detected in breast milk.

Advice regarding COVID-19 vaccination and blood clotting should be taken into consideration regarding vaccine selection, but does not alter the general advice that breastfeeding can continue after vaccination.

Infant monitoring

As with any medication exposure during breastfeeding, infants should be monitored. If the infant is not feeding as well as usual, or if there are any other concerns, a healthcare professional should be contacted.

Patient information

Patient information is available from the UK Health Security Agency (UKHSA) .
