A woman in South Florida who had received a dose of the coronavirus vaccine while pregnant recently gave birth to the first known baby who was born with Covid-19 antibodies “after maternal vaccination,” two pediatricians said.
The doctors presented their finding in a pre-printed article, which means that this claim has not yet been peer-reviewed.
Drs. Paul Gilbert and Chad Rudnick said the mother, a front-line healthcare worker, received her first dose of the Moderna vaccine in January, at 36 weeks pregnant.
The woman gave birth to a “vigorous and healthy” baby girl three weeks later. The researchers analyzed the baby’s umbilical cord blood and the antibodies “were detected … at the time of delivery,” according to their article. “Therefore, there is the potential for protection and reduction of the risk of Sars-CoV-2 infection with maternal vaccination.”
“As far as we know, this was the first in the world that a baby was reported to be born with antibodies after a vaccine,” Gilbert told the West Palm Beach ABC affiliate. “We tested the baby’s umbilical cord to see if the mother’s antibodies passed to the baby, which is something that we see happening with other vaccines given during pregnancy.”
However, the document makes clear that more research is needed to determine whether babies are protected by these antibodies, and writes: “We urge other researchers to create pregnancy and lactation registries, as well as to conduct efficacy and safety studies of Covid-19 vaccines in pregnant and lactating women and their offspring. “
“This is a small case in what will be thousands upon thousands of babies born to mothers who have been vaccinated over the next few months,” Rudnick told the local ABC station. “More studies must be done to determine how long this protection will last. They have to determine what level of protection or how many antibodies a circulating baby needs to protect it.
Gilbert and Rudnick told the affiliate that their article had been accepted for publication and that they were waiting for it to be officially published on the magazine’s site.
