Leite materno contém anti-corpos contra o covid-19
After COVID infection, antibodies have been found to persist in breast milk for at least six months, with emerging data suggesting they are still abundant ten months later. Antibodies are found in breast milk even after mild SARS-CoV-2 infections, and in women who have no symptoms at all.
Meanwhile, the breast milk of women who are vaccinated while lactating (who haven’t had COVID-19) has been found to contain significant levels of SARS-CoV-2 antibodies after vaccination. Determining how long SARS-CoV-2 antibodies in breast milk last after vaccination will take time, but reports suggest they persist for at least six weeks.
It’s not surprising that if the mother is infected with or vaccinated against COVID-19 we see SARS-CoV-2 antibodies produced in her breast milk. Pregnant women are often advised to be vaccinated against other diseases, such as whooping cough.
In these cases, we know the resulting antibodies that the mother produces can pass on to the baby through the placenta and in breast milk. This is known as “passive immunity”, meaning the baby gets immune protection while its own immune system matures to the point where it can make antibodies for itself.
It’s a continuation of a process that starts while the baby is developing in the womb, and receiving maternal antibodies that are passing across the placenta. This is very important to protect the baby against infectious diseases circulating in the community into which it’s born.
