As we report the latest findings from the REACT studies this week, I’d like to say a huge thank you to the hundred of thousands of people who have taken part. You make a major contribution to research - we couldn’t do this without you!

Latest findings from our community antibody prevalence study in England, pre-print here imperial.ac.uk/media/imperial… imperial.ac.uk/news/207333/co…

Levels of protective #antibodies in people wane over time after coronavirus infection. Latest results from @imperialcollege-led REACT study of more than 365,000 people in England.

Tests on more than 365,000 people in England have shown that the antibody response to the virus that causes #COVID-19 wanes over time

The antibody response to the virus causing #COVID19 declines over time, suggests the latest findings from our REACT study, which has tested over 365,000 people in England. Read more at

REACT2 latest results. Population antibody positivity fell by around 25% over 3 months. As with seasonal coronaviruses, this may mean falling levels of immunity. Smaller declines if younger and history of +ve PCR test. No change in healthcare workers. imperial.ac.uk/news/207333/co… pic.twitter.com/m8LveuOdLT

1/n L'étude REACT montre que le anticorps déclinent avec le temps, de 26,5% en 3 mois. Cela ne signifie pas qu' on ne serait pas protégé, le rôle des anticorps étant probablement accessoire imperial.ac.uk/news/207333/co… pic.twitter.com/o9Xj4T5TJa

A large study by scientists, Imperial College of London, tracking antibody levels in British population, says- Antibodies against Covid-19 declined rapidly over time, particularly among those who had an asymptomatic infection @AnantBhan @saahilmenghani imperial.ac.uk/news/207333/co… pic.twitter.com/xQpru5kapB

The Real-time Assessment of Community Transmission (REACT) study finds declining prevalence of antibody positivity in population to SARS-CoV-2 - raising questions about #HerdImmunity imperial.ac.uk/news/207333/co… - @imperialcollege study imperial.ac.uk/media/imperial…

New from #REACT study - COVID-19 antibody prevalence in the population has dropped. Lots of important unanswered questions about link between antibodies and protection / risk of reinfection. Follow @profhelenward for more!
