Breastfeeding moms who get COVID-19 vaccine pass protection onto baby, study finds

Nursing mothers who opt to get the COVID-19 vaccine may pass protective antibodies to their babies through breast milk for several months post-jab, a new study suggests.
The study, which only involved five mothers who provided researchers with frozen breast milk samples, focused on the Pfizer-BioNTech coronavirus vaccine.
The researchers saw elevated levels of the IgA and IgG antibodies immediately following the first dose of vaccination, with both antibodies reaching immune-significant levels within 14 to 20 days post-first dose.
"The antibodies levels were still high at the end of our study, so the protection likely extends even longer."
DON'T SKIP SECOND COVID-19 VACCINE DOSE, EXPERTS WARNThe study, which is peer-reviewed and was published in the American Journal of Obstetrics and Gynecology, is thought to be the first to track levels of antibodies in frozen breast milk over time.
The team acknowledged that the study is limited due to small size, but said the findings are encouraging nonetheless.
None of the currently approved COVID-19 vaccines in the U.S. included sufficient data in the emergency use authorization application regarding safety in pregnant or breastfeeding women.

Kelly said her team’s work also helps to disprove the "really scary, misleading posts on social media that are designed to scare moms."
"This is information we didn’t have a few months ago and it’s really helping us better counsel our patients who are considering getting the vaccine.
I’m telling my pregnant and breastfeeding moms that I strongly recommend that they get vaccinated as soon as possible."
