Study Shows Covid-19 Antibodies Over Time, Suggesting Immunity May Wear Off

The survey of 365,000 adults in England who tested themselves at home using a finger-prick test showed the proportion of people testing positive for Covid-19 antibodies declined by 26.5% between June 20—12 weeks after the peak of infections in the country—and Sept. 28.
