Researchers in the US called the best time for vaccination of pregnant women

Cornell University researchers have found that pregnant women have enough antibodies against the SARS-CoV-2 CORONAVIRUS in the blood to protect the fetus, regardless of whether the vaccine was given before or during pregnancy.

The results of the study are published in the journal Obstetrics & Gynecology. The highest level of antibodies in maternal blood and blood from the umbilical cord was detected with the introduction of the third, booster dose of the vaccine, in the third trimester of pregnancy, the scientists found.

The study involved 1359 women who gave birth to 1374 newborns - including 15 pairs of twins. All women had negative PCR tests at the time of delivery.

The vaccinated women received the first dose of the vaccine between December 16, 2020 and September 1, 2021; a second dose from January 5, 2021 to September 22, 2021 and a booster dose of the vaccine from August 27, 2021 to October 14, 2021.

Study participants were vaccinated between 6 weeks before pregnancy and 41 weeks of pregnancy.
