New study reveals COVID-19 antibodies stay for at least six months
A new study reveals most people infected with COVID-19 keep some antibodies to the virus for at least six months.
Researchers from UK Biobank measured levels of previous infection in more than 20,000 patients.
They found 99 percent of patients who had tested positive for COVID-19 retained antibodies for at least three months and 88 percent still had them six months later.
People under 30 and African-Americans were the most likely to have detectable antibodies.
About a quarter of people with antibodies were completely asymptomatic.
