The findings also suggest that vaccinating pregnant women can protect their unborn babies, as well, the researchers said – and it’s worth studying the possibility. Pregnant women are advised to get influenza vaccines for the safety of both themselves and their children.
Dr. Neonatologist of Children’s Hospital of Philadelphia. Dustin Flannery and colleagues studied more than 1,400 mothers and newborns. They found that protective IgG antibodies were transferred to the placenta in 72 out of 83 infected or previously infected pregnant women.
None of the infants of infected mothers developed coronovirus infection. Researchers reported that 60% of women had no symptoms of antibodies to coronovirus.
“Can maternal antibodies help delay the onset of an infection or protect an infant from getting infected, a serious illness, or dying of COVID-19?” Dr. Asked Flor Munoz, molecular virologist at the Baylor College of Medicine, who was not involved in the research.
The US Center for Disease Control and Prevention recommends vaccinating infants against the flu at six months, for example, even if mothers were vaccinated during pregnancy.
“To what extent can antibodies transferred through breast milk protect breastfeeding newborns?” Munoz asked.
“Should infants be vaccinated regardless of maternal infection, and if so, what is the best time to start infant vaccines? Is there a potentially harmful effect of maternal antibodies on infant responses to active immunization? ? And what will happen to optimal vaccines and vaccinations? For infants, given their risks and unique immunological needs? “
