As we know, breast milk is full of virtues for the newborn. It is particularly rich in antibodies, these cells of the immune system that protect us in the event of infection.
With the arrival of Sars-CoV-2, the challenge was to know if we could breastfeed while being infected (the answer is yes, because the virus does not pass into breast milk), and if the Protective antibodies produced by the mother were well transmitted to the infant. And again, the answer is yes.
Thus, breastfeeding your infant after having contracted Covid-19 or having been vaccinated allows the baby to be protected against this new virus.
In a new study (Source 1) published on December 23 in the journal Frontiers in Immunology, American researchers are publishing new data in this direction. They report that, on the one hand, breast milk does not contain the genetic heritage of the virus, and on the other hand, that he does provide protection against the virus for the newborn baby due to the presence of maternal antibodies.
The study was carried out on 64 breastfeeding women, in whom milk and nipple cell samples were taken several times, over a period of two months starting from the week of the diagnosis of Covid-19.
If the presence of the virus was found in the nipple samples, it was the result of the mother’s cough or some other type of external contamination. After washing the nipple, only two of the 29 nipple skin samples revealed the presence of Sars-CoV-2.
In contrast, 75% of 316 breast milk samples contained IgA antibodies to the novel coronavirus, whose concentration in the milk increased during the first two weeks after the onset of symptoms or the positive test. These antibodies persisted in the milk for at least two months in 77% of women, note the researchers. Enough to provide the baby with a lasting source of passive immunity, according to the authors, who see no reason to contraindicate breastfeeding in these times of pandemic, quite the contrary.
Data and recommendations that go in the same direction as those of the World Health Organization (WHO).
