COVID-19: antibodies found in the milk of vaccinated mothers | Digital Trends Spanish

A new study led by researchers at the University of Rochester and New York University found evidence that mothers with immunity to COVID-19 (acquired by disease or vaccines) produced breast milk with active antibodies against SARS-CoV -2.

According to the study, mothers with acquired immunity to the disease produced high levels of immunoglobulin A (IgA) antibodies against the virus in breast milk, while the immunity acquired by the vaccine produced strong immunoglobulin G (IgG) antibodies. ).

Both antibodies provide neutralization against the virus and this is the first time that tests of this type have been discovered for IgA and IgG, according to the study authors.

“It is one thing to measure antibody concentrations, but it is another to say that the antibodies are functional and can neutralize the SARS-CoV-2 virus,” explained Bridget Young, a co-author of the research.

“One of the exciting findings of this work is that breast milk, both from mothers with COVID-19 infection and from mothers who received the mRNA vaccine, contained these active antibodies that were capable of neutralizing the virus.”

Previous studies had shown the presence of antibodies in the breast milk of mothers infected with COVID-19.

Either way, the researchers claim that these antibodies cannot substitute for vaccination in minors.

“The study does not imply that children are protected from the disease and antibodies in breast milk cannot be a substitute for vaccination for infants and children, once approved.”
