Latest results from the REACT-1 study on COVID-19 prevalence across England

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. 

Speakers included:

Prof Paul Elliott, FMedSci, Director of the REACT programme, and Chair in Epidemiology and Public Health Medicine, Imperial College London

Prof Christl Donnelly, WHO Collaborating Centre for Infectious Disease Modelling, MRC Centre for Global Infectious Disease Analysis, Abdul Latif Jameel Institute for Disease and Emergency Analytics (J-IDEA), Imperial College London; and Department of Statistics, University of Oxford

This Briefing was accompanied by an SMC Roundup of Comments.
