REACT-2: real-time assessment of community transmission – antibody waning

REACT-2 is a world largest surveillance study undertaken in England that examines the prevalence of antibodies in the community. The study focusses on finger prick self-testing at home by individuals aged 18 or over. The findings will provide the government with a better understanding of the use of antibody tests at home as well as assess the trends in antibody levels and how they vary across different population subgroups. In this publication 3 rounds of test results and feedback were compared to identify potential antibody waning.
