It’s a double benefit. According to a new American study, babies born to mothers vaccinated during pregnancy 61% less risk of being hospitalized with Covid-19. These findings were released by the US Centers for Disease Control and Prevention (CDC). This study was conducted on babies up to six months old and hospitalized between July 2021 and January 2022.
For the researchers, this protection certainly results from a transfer of antibodies against the virus between a pregnant mother and her baby, through the placenta. “The majority of babies, in fact 84%, who were hospitalized with Covid-19 were born to people who were not vaccinated during pregnancy. And most worryingly, they found that among babies with Covid-19 who were admitted to intensive care, the sickest babies – 88% were born to mothers who were not vaccinated before or during pregnancy,” said CDC researchers Dr. Dana Meaney-Delman. The only baby who died during the study had a mother who was not vaccinated against Covid-19.
Two injections after 21 weeks of gestation
“There is a huge benefit to pregnancy and having a healthy, vaccinated mother before pregnancy. I don’t want us to lose sight of that. Although we don’t know that real immune protection is conferred, we know that it could prevent a mother from contracting Covid during pregnancy, which is associated with premature birth, stillbirth, with pregnancy complications”, explains Dr. Dana Meaney-Delman.
This study reports that the timing of the injections is not trivial regarding the protection of infants. Indeed, vaccination has been shown to be 80% effective in protecting a newborn against a severe form of the disease if a mother received her two injections after 21 weeks of gestation. To avoid taking any risks, the CDC recommends that pregnant women, those who are breastfeeding or who could soon be expecting a child get vaccinated against Covid-19.
