Pregnant or breastfeeding women can receive the COVID-19 vaccines.

Pfizer-BioNTech/Comirnaty and Moderna/Spikevax Vaccines

Internationally, a large number of pregnant and breastfeeding women have received a COVID-19 vaccination.  There have been studies done to monitor women who were vaccinated when they were pregnant, and their babies. These studies were done on women at different trimesters of pregnancy and there is no evidence to suggest that the Pfizer-BioNTech/ Comirnaty or Moderna/Spikevax COVID-19 vaccine may cause harm to pregnant women or their babies. 

Both Pfizer-BioNTech/Comirnaty and Moderna/Spikevax COVID-19 vaccines are mRNA vaccines. As mRNA vaccines are not live vaccines, they are biologically unlikely to adversely affect breastfed babies. In addition, the breast milk of vaccinated mothers may help to protect their babies from COVID-19 due to antibodies in breast milk. There have also been no vaccine-related side effects reported in the babies who were breastfed by mothers who received the vaccine while breastfeeding.
