Anew studyfrom researchers at New York University found high levels of coronavirus antibodies in the blood of newborns whose mothers had received the Pfizer or Moderna vaccine. The study looked at 36 newborns and found that all of them had antibodies when they were delivered. headtopics.com
Mothers who'd been vaccinated 13 weeks before giving birth seemed to pass along higher levels of antibodies than mothers who'd been vaccinated more than 20 weeks before giving birth. But the researchers said more data is needed to determine whether there's really a correlation between the timing of the vaccine and a newborn's antibody levels.
It's also not yet clear how well the newborn babies were protected from coronavirus infections, or how long that protection might last. Still, the researchers suggested coronavirus antibodies may give infants protection during the neonatal period - their first four weeks - or longer.
"If babies could be born with antibodies, it could protect them in the first several months of their lives, when they are most vulnerable," Ashley Roman, one of the study authors, said ina press release.The team wrote that their findings "add to a growing list of important reasons why women should be advised to receive the COVID vaccine during pregnancy."

Antibodies can travel from the placenta to unborn children through the umbilical cord. Newborns can also take in these antibodies through breast milk. That's true for antibodies from other vaccines, too, like the flu shot. headtopics.com
