Babies receive Covid-19 antibodies from mothers while in the womb

Study finds out that antibodies that protect us against coronavirus can move from the mother to the infant during pregnancy, which shows that the mother somehow can provide protection to their kid during their pregnancy with the antibodies they receive.

Scientists agree that it is worth studying the possibility on vaccinating pregnant women to provide protection to their unborn babies. Pregnant women should be advised to receive Covid antibody treatment to protect both their body and the baby.

Newborn specialist Dr. Dustin Flannery of Children’s Hospital of Philadelphia and colleagues found out that after studying more than 1,400 mothers and their infants, protective IgG antibodies are transferred across the placenta in 72 out of 83 infected or previously infected pregnant women they studied.

Until now, 60% of mothers that have received treatment displayed no coronavirus symptoms, and the none babies that had infected mothers developed coronavirus infection. This shows the great possibility of the specific antibodies to provide neonatal protection from coronavirus disease.

Dr. Flor Munoz, a molecular virologist at the Baylor College of Medicine, who was not involved in the research, asks “Could maternal antibodies help delay the onset of infection or protect the infant from becoming infected, having severe disease, or dying of COVID-19?” 

Munoz says, even though protection from antibodies are welcomed to vulnerable babies, more studies will have to be done about when and how to vaccinate infants since it is also known that antibodies against other viruses, such as influenza or tetanus, wear off quickly when passed from mother to infant during pregnancy.

The US Centers for Disease Control and Prevention recommends immunizing babies against the flu at six months, for instance, even if the mothers were vaccinated during pregnancy.

Munoz further asked questions about the plausibility of infants receiving Covid antibodies. “Should infants be vaccinated regardless of maternal infection, and if so, what is the best timing to initiate infant vaccines? Is there a potential detrimental effect of maternal antibodies on infant responses to active immunization? And what would be the optimal vaccine and vaccination regimen for infants, considering their risk and unique immunologic needs?”
