A woman in South Florida who received a dose of the coronavirus vaccine during her pregnancy recently gave birth to the first known baby born with Covid-19 antibodies “after maternal vaccination,” two pediatricians said.
Doctors presented their findings in a preprinted article, which means this claim has yet to be peer reviewed.
Drs. Paul Gilbert and Chad Rudnick said the mother, a frontline worker, received her first dose of Moderna vaccine in January, at 36 weeks pregnant.
The woman gave birth to a “vigorous and healthy” daughter three weeks later. The researchers analyzed the baby’s umbilical cord blood and antibodies “were detected… during childbirth,” according to their article. “Thus, there is the potential to protect and reduce the risk of Sars-CoV-2 infection through maternal vaccination.”
“To our knowledge, this was the first in the world that has been reported that a baby was born with antibodies after a vaccination,” Gilbert told the ABC West Palm Beach affiliate. “We tested the baby’s cord to see if the mother’s antibodies were passed on to the baby, which we are seeing with other vaccines given during pregnancy.”
The paper makes it clear, however, that more research is needed to determine whether infants are protected by these antibodies, writing: “We urge other researchers to create pregnancy and breastfeeding registries and to conduct studies of these antibodies. efficacy and safety of Covid-19 vaccines in pregnant and lactating women and their offspring. “
“This is a small case in what will be thousands and thousands of babies born to mothers who have been vaccinated over the next several months,” Rudnick told the local ABC station. “Further studies need to determine how long this protection will last. They need to determine what level of protection or how many antibodies a baby needs to have circulating to give protection. “
Gilbert and Rudnick told the affiliate that their article has been accepted for publication and that they are waiting for it to be officially published on the journal’s website.
