COVID Vaccines and Breastfeeding
The vaccine does not pass through breast milk, but antibodies do, raising hope babies may have some level of protection
Scientists are beginning to understand the effects of COVID-19 vaccines on breast milk, and their preliminary results should come as welcome news to the more than 100 million lactating people across the world.
Scientists have so far looked only at two of the vaccines in circulation, Pfizer–BioNTech and Moderna, and have not detected the vaccines in breast milk. What they have found are antibodies, produced by mothers in response to inoculations, to the coronavirus SARS-CoV-2.
“We’re really happy to have something good to hang our hat on,” says Stephanie Gaw, a perinatologist at the University of California, San Francisco. “The studies are small, they’re still early, but very positive.” Now, researchers want to know whether those antibodies can provide babies with at least partial protection against COVID-19.
