Washington University Research Ties Bone Marrow to Covid-19 Antibodies in Survivors of the Virus

St. Louis researchers from Washington University are suggesting Covid-19 immunity may be longer-lasting than previously thought.

The St. Louis Post Dispatch is reporting that in the bone marrow of a small group of COVID-19 survivors, researchers found cells that produce antibodies that protect against the virus.

In a study released in the magazine “Nature”, researchers show that among a group of 19 participants who previously had mild cases of COVID-19, 15 had antibody-producing cells in their bone marrow that target the virus that causes COVID-19. The researchers took bone marrow samples from 18 participants seven to eight months after their initial infections.

The cells were still found four months later in the five participants who returned.
