COVID Is Not Transmitted Through Breast Milk, Although It Does Produce COVID-Fighting Antibodies.

Breastfeeding women with COVID-19 do not transmit the SARS-CoV-2 virus through their milk, according to a study conducted by researchers at the University of Rochester Medical Center (URMC) in collaboration with several other universities. They do, however, confer milk-borne antibodies that can neutralize the virus.

The study, "Characterization of SARS-CoV-2 RNA, antibodies, and neutralizing power in milk produced by women with COVID-19," was published recently in the journal mBio and looked at 37 milk samples from 18 women who had COVID-19.

The virus was not discovered in any of the milk samples, but roughly two-thirds of them did contain two antibodies specific to the virus. Critically, this study provides evidence that COVID-19 positive mothers shouldn't be separated from their newborn children.

At the onset of the pandemic, major health organizations have often provided contradictory advice on whether this separation was necessary.

"We only want to sequester a mother from her baby if it's medically necessary," said co-investigator Bridget Young, Ph.D., professor within the Department of Pediatrics at 

URMC, "However, the issue was very confusing for practitioners who don't have sufficient evidence.

The URMC research group is led by Antti Seppo, Ph.D., within the Department of Pediatrics.

Scientists from the University of Rochester School of Medicine and Dentistry, Brigham and Women's Hospital and Harvard Medical School, and the University of Idaho were also part of the research team.

The team has now enrolled approximately 50 women who are diagnosed with COVID-19 and has been following their progress for up to 2 months.

The study was started in response to a dearth of studies on COVID-19 in breastmilk.

The next step will be to investigate if the preliminary findings can be duplicated in larger groups.

This study has to be repeated with larger groups of people."We also need to figure out if the COVID-19 vaccine has the same effect on breast milk," Young added.
