Bone marrow from patients who recovered from Covid-19 revealed that the immune system’s ability to recognise and fend off the SARS-CoV-2 virus lasts at least a year.
In a study, published in the journal Nature Monday, researchers described how bone marrow plasma cells (BMPCs) — an essential source of protective antibodies that bind to the spike protein of the coronavirus — persist up to 11 months after Covid infections.
Conducted by a team from Washington University in the US, the study is the first direct evidence on the production of pathogen-specific bone marrow plasma cells after a viral infection in humans.
