The REACT-1 team from Imperial College London has now completed round 14 of their study looking at virus prevalence across England.
This batch of data includes over 100,000 participants.
The study gives an in-round estimate of R and prevalence of infection in England and a breakdown for different regions and demographics. The study also gives an estimate of vaccine effectiveness against infection.
Please note this data is a preprint, so it is early work that has not yet been through peer-review and is not published in a journal.
