Research New shows that women who have been vaccinated for corona pass on high levels of antibodies to their babies. Thirty.six infants tested at birth had antibodies to protect against the virus after their mothers were vaccinated with Pfizer and Moderner vaccines. So rises fromNew data published in the American Journal of Obstetrics & Gynecology maternal fetal medicine.
This study is one of the first studies to measure the levels of antibodies in the umbilical cord blood, to test for immunity and it joins a recent study at Assuta Hospital in Ashdod among 40 women who found that babies of vaccinated mothers have three times the amount of antibodies compared to other babies. Already at the beginning of the year, the World Health Organization announced that no risks were found in the vaccine for pregnant women, and based on the information accumulated, there is no reason to assume special risks in pregnancies compared to the rest of the population.

As part of the study, the researchers examined the umbilical cord blood of 36 vaccinated women to look for antibodies to a prickly protein, which appears after the vaccine. Unlike previous studies that focused on antibodies to the spike protein, the present study tested resistance to the nucleocapsid protein, which is associated with the corona virus.
Of the 36 samples examined by the researchers, 31 were tested negative for antibodies to the nucleocapsid protein. In other words, 31 pregnant women developed immunity to the vaccine. The other five have not been tested for the nucleocapsid protein, so researchers cannot say unequivocally whether the immunity is from the vaccine or formed naturally.
The findings show “very encouraging levels of umbilical cord blood antibodies,” said Linda Eckert, a professor of gynecology at the University of Washington who was not involved in the study. “This is another reason pregnant women need to get vaccinated, as we are seeing more disease in young babies. It is an initiated choice that pregnant women can make to protect their babies.”

Pregnant women are afraid to get vaccinated
These data can help encourage more women to get vaccinated during pregnancy. Only 30% of pregnant women between the ages of 18 and 49 are vaccinated in the U.S., according to the Centers for Disease Control and Prevention as of mid.September, despite growing evidence for the safety of prenatal vaccines. And how long the vaccine helps babies after birth.
Alongside this, Pfizer announced last week that it was discontinuing registration for an experiment it began to conduct on pregnant women, due to slow enrollment and “vaccine safety that has been universally proven in all situations.”
