Soon after acquiring COVID-19, most people’s bodies develop antibodies to help combat it off. These are specific molecules designed by the body’s illness protection process, the immune process. A study discovered that people with these antibodies were being a lot less very likely to get COVID-19 again.

Scientists seemed at a lot more than three million people who experienced an antibody exam for SARS-CoV-2. SARS-CoV-2 is the virus that triggers COVID-19.

They discovered that about 11% of people experienced SARS-CoV-2 antibodies. More than 88% experienced a destructive exam. And a lot less than 1% of checks were being inconclusive.

The experts seemed at who came down with COVID-19 soon after the exam. They analyzed up to 30 times, 31–60 times, 61–90 times, and a lot more than 90 times soon after.

About three% to four% of people with destructive antibody checks bought COVID-19 in just about every time interval. But those who experienced antibodies were being a lot less very likely to have COVID-19 as time went on. Only .three% of the people with antibodies experienced a constructive COVID-19 exam a lot more than 90 times soon after. Those with out antibodies were being 10 times a lot more very likely to get the illness.

The conclusions advise that people who have a constructive result from an antibody exam may be at reduced chance for foreseeable future an infection with SARS-CoV-2.

NIH’s Dr. Lynn Penberthy, who led the analysis staff, points out that a lot more issues even now want to be answered. “We are nonetheless encouraged by this early locating,” she suggests.
