COVID-19 immune cells fend off the virus and prevent illness - study
Eight months after infection, most people who have recovered still have enough immune cells to fend off the COVID-19 virus and prevent illness, reported New York Times, quoting recent research.
“That amount of memory would likely prevent the vast majority of people from getting hospitalized disease, severe disease, for many years,” said Shane Crotty, a virologist at the La Jolla Institute of Immunology who co-led the new study.
And the research squares with another recent finding: that survivors of SARS, caused by another coronavirus, still carry certain important immune cells 17 years after recovering.
Another study published last week also found that people who have recovered from Covid-19 have powerful and protective killer immune cells even when antibodies are not detectable.
