Groups such as the National Hospital Organization Mie Hospital have summarized the results of research that confirmed that antibodies were transferred to babies by vaccinating pregnant women with the new coronavirus.


Vaccination is said to protect pregnant women and their unborn babies.

A group led by Hidehide Suga, deputy director of the National Hospital Organization Mie Hospital, analyzed the postnatal blood and umbilical cord blood of 146 pregnant women who received two doses of Pfizer's new coronavirus vaccine, and is suppressing the action of the virus. I checked how many Japanese antibodies there were.   



As a result, the level of neutralizing antibody in cord blood was 1.68 times higher than that in the mother's blood, and it was confirmed that when a pregnant woman is vaccinated, the antibody is transferred to the baby through the placenta.



Analysis of when the second dose of the vaccine resulted in higher transfer antibody levels was highest between the 28th and 34th weeks of pregnancy, but remained constant even if the vaccine was given early in pregnancy or close to delivery. It means that we were able to confirm that a moderately high level of antibody has migrated.

Deputy Director Suga said, "In order to protect newborns from diseases, it is important to give them a lot of immunity from their mothers. For the sake of the pregnant women themselves and to protect their unborn babies, it is important to consider vaccinations for pregnant women. I want it," he says.
