Mothers Previously Contracted With Covid-19 Can Produce Antibodies In Their Breastmilk


A study conducted by Rebecca Powell and a couple other colleagues from Mount Sinai Hospital, New York presented new data on mothers who had previously contracted the Covid-19 virus. They analysed breastmilk samples from 75 lactating women, and 88% of the samples found antibodies against the SARA-CoV-2 virus which were even capable of neutralising the virus in most cases.


The antibodies detected in the milk samples were found to be different from Immonoglobin G (IgG) antibodies that are triggered by vaccinations and found mostly in the bloodstream. Meanwhile, the milk samples contained more of Secretory Immunoglobin A (IgA), which sticks to the linings of babies’ respiratory and intestinal tracts, helping to prevent the virus from infecting their bodies.


Apparently, this wasn't the first study done on breastmilk, experts had already detected SARS-CoV-2 antibodies earlier but wasn't sure whether they could successfully neutralise the virus, or the amount of time they would need to continue to be produced in the milk following the mother's infection.


“This is the breastfeeding population, so knowing if there are antibodies in the milk, how long they’ll be proactive after being infected, or which vaccine is going to give your body the best antibody protection, is very important information, and will be relevant for a long time to come,” said Powell.


The team's study could be extremely beneficial not only to babies, but to adults that are still suffering from Covid-19.
