According to an article in HealthDay News, there is some very good news to emerge from the coronavirus pandemic.
New research shows that pregnant women and breastfeeding moms have a strong immune response to COVID vaccines and can transfer that immunity to their infants
The study, involving 131 women of reproductive age, 84 of them pregnant, who had received an mRNA vaccine either from Pfizer/BioNTech or Moderna found that pregnant and breastfeeding individuals had strong immune responses to vaccination and that the antibodies can be passed on to their infants.
In addition, the antibody levels triggered by vaccination were much higher than levels induced by natural infection with COVID in pregnancy, the researchers said.
“This news of excellent vaccine efficacy is very encouraging for pregnant and breastfeeding women who were left out of the initial COVID-19 vaccine trials,” said study co-senior author Dr. Andrea Edlow, a maternal-fetal medicine specialist at Massachusetts General Hospital (MGH).
The researchers also found that levels of mucosal (IgA) antibodies were higher after the second dose of Moderna compared to the second dose of Pfizer.
This finding is important for all individuals since COVID is acquired through mucosal surfaces like the nose, mouth, and eyes. But it also holds special importance for pregnant and lactating women because IgA is a key antibody present in breast milk.
The findings were published in the American Journal of Obstetrics and Gynecology.
