Pregnant or breastfeeding women were not able to participate in the clinical trials to test the Pfizer or Moderna COVID-19 vaccines. But a new study appears to show that mothers who have received the vaccine have antibodies in their breast milk that may protect their infants. The study, which appears in the preprint server medRxiv and has not yet been peer reviewed, shows that there were significantly elevated levels of COVID-19 antibodies in breast milk beginning at Day 7 after the initial vaccine dose. If this research proves to be true, it suggests that babies may be protected from COVID-19 by antibodies they get through breast milk after their mothers are vaccinated.
