Dand according to a new North American research released in the iScience, the breast milk of patients who recovered from Covid-19 contains antibodies against pathology, reports an article published in the magazine Galileu.

Medical School Researchers Icahn in Mount Sinai, in the United States, examined samples from eight donors who had been infected for the new coronavirus, and seven with suspected infection.

The scientists wanted to identify the presence of antibodies Age, which are commonly found in body secretions.

Of the 15 samples analyzed, explains the magazine Galileu, 80% showed a strong response from Age against SARSCoV-two. Furthermore, 67% contained antibodies IgG (present in greater quantity in the body) and IgM (they are formed as a consequence of the primary response to a pathogen). Since these defense molecules are associated directly to the new spike protein coronavirus to combat infection.

“Overall, this data indicates that a robust response from sIGE-dominant [anticorpo IgA normalmente encontrado em muco] to SARSCoV-2 Ab in human milk after infection should be expected in a significant majority of individuals “, pointed out the study authors.

However, scientific work has some limitations, because not all volunteers have been subjected to an examination of the type PCR, so it cannot be stated with absolute certainty that they had Covid-19. Hence more research is imperative.

Additionally, it remains to be seen whether antibodies provided by breast milk can actually protect babies from Covid.

The scientists said: “the immune response SARSCoV-2 in human milk has not yet been examined, although protecting infants and young children from Covid-19 is critical to limiting transmission in the community and preventing serious illness and death. ”
