New England Journal of Medicine.The immune system remembers how to make fresh antibodies if needed and other parts of it also can mount an attack, he said.Antibodies are proteins that white blood cells called B cells make to bind to the virus and help eliminate it.
The earliest ones are fairly crude but as infection goes on, the immune system becomes trained to focus its attack and to make more precise antibodies.Dr.
Otto Yang and others at the University of California, Los Angeles, measured these more precise antibodies in 30 patients diagnosed with COVID-19 and four housemates presumed to have the disease.
Their average age was 43 and most had mild symptoms.Researchers found that the antibodies had a half-life of 73 days, which means that.
