According to an article by Contemporary OB/GYN, researchers compared vaccine-generated immunity to immunity gained from natural infection with the virus. In fact, pregnant women who received either of the vaccines elicited comparable humoral immune responses when compared to non-pregnant controls, they said. Those who received either vaccine also generated higher antibody titers compared to those observed in those with actual COVID-19 infection in pregnancy. The antibodies were present in breastmilk and umbilical cord blood after vaccination.
