According to American researchers, newborns whose mothers were vaccinated against Covid during their pregnancy would have antibodies transmitted via the placenta, and would be 60% less likely to be hospitalized due to the virus.
Vaccination of pregnant women against Covid-19 is recommended from the start of pregnancy, to protect future mothers and their fetus. But it would also protect babies at birth, as revealed by a new American study, published on February 15, 2022. According to researchers from the Centers for Disease Control and Prevention (CDC), babies whose mothers were vaccinated during pregnancy are 61% less likely to be hospitalized Covid-19. To reach this conclusion, the study authors followed babies hospitalized between July 2021 and January 2022 and aged less than 6 months.
84% of hospitalized babies were born to unvaccinated mothers
If babies born to a mother who received a dose of vaccine during pregnancy are less affected by hospitalizations, this is not the case for those whose mothers were not vaccinated during pregnancy. Indeed, 84% of babies who were hospitalized were born to mothers who had not been vaccinated. The researchers also recorded a death and in this case, the mother was not vaccinated either. The researchers specify that only mothers who received two doses of vaccines or their second dose Pfizer or Moderna were included in the study. Women who had been vaccinated before conceiving their child were therefore not taken into account. “In summary, maternal vaccination is a very important way to help protect these young babies“, CDC researcher Dana Meaney-Delman said during a press briefing.
