Babies in womb get Covid-19 antibodies from mothers - study

Antibodies that protect against the coronavirus often get transferred from mother to infant during pregnancy -- a finding that indicates a mother passes along at least some protection to her child, researchers reported Friday.

The findings also suggest that vaccinating pregnant women might protect their unborn babies, as well, the researchers said -- and it's worth studying the possibility. Pregnant women are advised to get influenza vaccines to protect both themselves and their babies.

Newborn specialist Dr. Dustin Flannery of Children's Hospital of Philadelphia and colleagues studied more than 1,400 mothers and newborns. They found that protective IgG antibodies were transferred across the placenta in 72 out of 83 infected or previously infected pregnant women they studied.

"Our findings demonstrate the potential for maternally derived SARS-CoV-2 specific antibodies to provide neonatal protection from coronavirus disease 2019," the team wrote in the Journal of the American Medical Association's JAMA Pediatrics.

None of the babies of infected mothers developed coronavirus infection. And 60% of the women who had antibodies to coronavirus had no symptoms, the researchers reported.

"Could maternal antibodies help delay the onset of infection or protect the infant from becoming infected, having severe disease, or dying of COVID-19?" asked Dr. Flor Munoz, a molecular virologist at the Baylor College of Medicine, who was not involved in the research. (CNN)
