Q. Can I have a COVID-19 vaccine if I am breastfeeding?

The JCVI advice published on 30 December 2020 says there is no known risk in giving available COVID-19 vaccines to breastfeeding women.

Breastfeeding women will now be offered vaccination at the time when they become eligible.

Although there is lack of safety data for these specific vaccines in breastfeeding, there is no plausible mechanism by which any vaccine ingredient could pass to your baby through breast milk. You should therefore not stop breastfeeding in order to be vaccinated against COVID-19.
