Dr. Jeannie Kelly

An assistant professor of obstetrics and gynecology at the Washington University School of Medicine in St. Louis and lead author of a study on SARS-CoV-2 antibodies in breast milk following vaccination.

“We did not measure spike protein levels in our study. However, there is no evidence that the spike protein is in breast milk… Much like any other vaccination in a breast feeding person, even if the spike protein makes it into the milk, the protein would be degraded by the stomach acid. Even if the spike protein was absorbed into the blood stream, it has no mechanism of action to cause any issues such as bleeding disorders.”
