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
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.
Levels of protective #antibodies in people wane over time after coronavirus infection. Latest results from -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
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
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
