In the first nine months of the epidemic, approximately 116 million babies were born worldwide UNICEF estimates. This left researchers to answer an important question: can the virus be transmitted through breast milk? Some people accepted this. but as Several groups of researchers Tested milk, they found no traces of the virus, only antibodies – suggesting that drinking milk could protect infants from infection.
The next big question for breast milk researchers was whether the protective benefits of the Kovid vaccine could similarly be passed on to infants. None of the vaccine trials included pregnant or lactating women, so researchers had to find breastfeeding women who were previously eligible for the vaccine rollout.
Rebecca Powell, a human lactologist at the Icon School of Medicine in Mount Sinai, Manhattan, found hundreds of doctors and nurses ready to share her breast milk periodically through a Facebook group. In it The most recent study, Which has not been formally published, it analyzed the milk of six women who received the Pfizer-Bayontech vaccine and four who received the modern vaccine, 14 days after the women received their second shots. She found significant numbers of a specific antibody called IgG in all of them. Similar results have come from other researchers.
“There is reason to be excited,” said A maternal fetal medicine specialist at Brigham and Women’s Hospital in Boston, Drs. Katherine Gray, who has done similar studies. “We believe that can provide some level of security.”
But how do we know for sure? One way to test this – exposing those children to the virus – is certainly unethical. Instead, some researchers have tried to answer this question by studying the properties of antibodies. Are they neutralizing, meaning they prevent the virus from infecting human cells?
In the draft of a small study, an Israeli researcher found that they were. “Breast milk has the ability to block viral spread and block the virus’ ability to infect host cells, which will result in disease.” Yariv wine, An applied immunologist at Tel Aviv University, wrote in an email.
Research is too premature for vaccinated mothers who are acting to breastfeed such that their babies cannot become infected, however, the head of pediatric allergy and immunology at the University of Rochester’s Center Center, Drs. Kirsi Järvinen-Seppo said. Conducting similar studies. “There is no direct evidence that Kovid antibodies in breast milk are protecting the infant – only pieces of evidence suggest that may be the case,” she said.
