A 36-week-pregnant, South Florida-based frontline healthcare worker got her first shot of a modern CVWID-19 The vaccine. She gave birth to a healthy baby girl three weeks later – with COVID-19 antibodies.
Doctors believe that the newborn U.S. In coronavirus marks the first known case of a baby born with antibodies, which gives him little protection against the virus.
Dr. Paul. Paul Gibert and Drs. Chad Rudnik presented his findings in a printprint study, which means it has not yet been peer-reviewed. They found that the antibodies were found at the time of delivery, immediately after birth and after analysis of blood from the baby’s uterine blood taken before placenta delivery.
“We have shown that SARS-CoV-2 IgG antibodies can only be detected in a newborn’s blood sample after a dose of Moderna Covid-19 vaccine.” “Thus, maternal vaccination with SARS-COV-2 is likely to reduce the risk of protection and infection.”
Doctors emphasize, however, that more research is needed Check safety and effectiveness No. Coronavirus vaccines during pregnancy.
It was already known that mothers previously infected with COVID-19 could give antibodies to their newborns. Additionally, the passage of antibodies from placenta to mother to child has been well documented in other vaccines, including influenza, so doctors hope that the same neonatal protection against maternal vaccination against covid-19 is possible.
Internal medicine specialist and immunologist Dr. Nita Ogden, “We are starting to combine the covid vaccine with the vaccine already used in pregnant women, like the flower vaccine.” Told CBSN On wednesday “We really need it, and it’s clear that what we need is significant data on how safe it is in pregnant women.”
These preliminary results may help give pregnant women more reason Think about getting a vaccine.
“This is also optimistic as it provides a level of protection to the newborn, one of the most vulnerable populations,” Ogden said, emphasizing the need for further study in pregnant women during the epidemic.
Because we do not have the Covid vaccine For children Still, she said, “If we could look at this kind of safe maternal transition of antibodies from vaccines to newborns, I think it’s really a great step in the right direction.”
Other recent studies, also published in print and not peer-reviewed, support these findings.
Massachusetts General Hospital recently studied 131 women – 84 pregnant, 31 breastfeeding and 16 non-pregnant – who received Pfizer or Moderna vaccines. They found equally strong immune responses in pregnant and breastfeeding women as a control group. Additionally, antibodies were present in the placenta and lactation of each sample taken.
Maternal and fetal medicine specialist at Massachusetts General Hospital, co-author Dr. “Antibodies produced by the maternal vaccine were found in the uterine blood of all 10 children who gave birth during the period of our study,” Andre Adlow told CBS News on Wednesday. “Our data suggest that receiving both shots of the mRNA vaccine leads to antibody transfer in the newborn.”
Another study outside of Israel found antibodies in 20 women examined who received both doses of the Pfizer vaccine, both during their third trimester and also through placental transfer in their newborns.
Last month, Pfizer announced that it had begun the first large-scale trial of its vaccine on pregnant women, which it expects to complete by early 2023. His vaccine was released in the U.S. in December. The emergency was approved for use in, and millions of people, including thousands of pregnant women, have already missed it.
Moderna, whose vaccine was also released in the U.S. in December. Has received authorization for emergency use, has not started trials focusing on pregnancy, but has created a registry to track pregnant women who have received its vaccine. Johnson and Johnson, who received authorization of emergency use for its vaccine last month, said it plans to include pregnant women and their babies in its study, as well as collect data about pregnant women through the registry.
Pregnant women were excluded from the original tests of Moderna and Pfizer’s COVID-19 shots, as is common practice in such studies.
