The findings of a recent study suggested that antibodies that help in guarding against the COVID-19 virus are transferred from mothers to their babies while in the womb. This discovery, published in the American Journal of Obstetrics and Gynecology', adds to growing evidence that suggests that pregnant women who generate protective antibodies after contracting the coronavirus often convey some of that natural immunity to their fetuses.
The findings also lend support to the idea that vaccinating mothers-to-be may also have benefits for their newborns. All of the women had COVID-19 antibodies in their blood, indicating that they had contracted the virus at some point even though 58 percent of those women had no symptoms. Furthermore, while antibodies were detected in both symptomatic and asymptomatic women, the researchers observed that the concentration of antibodies was significantly higher in symptomatic women.
