MANAUS – Researchers at the University of Florida (USA) reported what they classify as ‘the first case in the world of antibodies against Covid-19 found in a newborn’. The mother, a frontline health professional, received a dose of Moderna’s vaccine three weeks before delivery.

The study is preliminary and was published on the medRvix platform. It has not yet been reviewed by other scientists. “We demonstrated that IgG antibodies to SARS-CoV-2 are detectable in a newborn’s umbilical cord blood sample after a single dose of the vaccine. Therefore, there is potential to protect and reduce the risk of SARS-CoV-2 infection with maternal vaccination ”, say the scientists.

The researchers warn that further studies will be needed to find out the amount of neutralizing viral antibodies present in the newborns of mothers who are vaccinated before delivery. They also explain that the duration of antibody protection is still unknown.

Vaccination of pregnant women

In Brazil, the Ministry of Health says that the vaccination of pregnant women can be carried out “after a careful assessment of the risks and benefits and with a shared decision, between the woman and her prescribing physician”.

The World Health Organization (WHO) recommends the immunization of pregnant women at high risk of coronavirus exposure, as in the case of a health professional or with comorbidities. “Vaccination can be considered if discussed with your doctor,” warns the WHO.
