Most of the women who had the virus developed antibodies, but the transfer of those antibodies to newborns through the placenta was significantly lower than the transfer of anti-flu antibodies, the study found.

The researchers said their work suggests that pregnant women are “a key population to consider in vaccine rollouts.”
