The WHO Strategic Advisory Group of Experts on Immunization (SAGE) interim recommendations state that if a breastfeeding mother is part of a high-risk group e.g. she’s a health worker or in a group recommended to have a vaccination, a vaccine can be offered.  Whilst research on COVID-19 vaccines did not include women who were breastfeeding, the absence of direct data does not mean the vaccines are not safe. According to the CDC neither inactivated nor live-virus vaccines, like the AstraZeneca and Janssen vaccines, pose a risk for mothers who are breastfeeding or for their infants. (Except for smallpox and yellow fever vaccines – these are not given to lactating mothers). The Pfizer–BioNTech and Moderna vaccines do not contain a live virus. The mRNA in these vaccines does not enter the core of the cell, and is degraded quickly. According to the CDC, the COVID-19 vaccines are thought not to be a risk to a child breastfeeding or receiving breast milk. The vaccines are considered to be effective in breastfeeding mothers and even pass on protection to the baby through breast milk. Therefore, the WHO SAGE guidance recommends that mothers who are vaccinated continue breastfeeding.
