COVID-specific antibodies remain in breast milk for 10 months post infection

For the study, the team took breast milk samples from 75 women who had recovered from COVID-19 and found that 88 percent contained IgA antibodies. In most cases, these were capable of blocking infection.  

New York: COVID infection in breastfeeding women produces virus-neutralising antibodies that remain in their milk for up to 10 months, finds a new study.

The study led by Icahn School of Medicine at Mount Sinai Hospital in New York showed that the antibodies in breast milk -- Secretory Immunoglobulin A -- are different to the Immunoglobulin G (IgG) antibodies that is found in human blood and are triggered by COVID vaccination, the Guardian reported.

The study was presented at the recent 15th Global Breastfeeding and Lactation Symposium.
