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

We recently heard from the REACT-1 scientists with interim results from round 13 of their study looking at virus prevalence across England.  They now have the full set of data in for this round.

This batch of data includes almost 100,000 swab tests carried out across England between 24 June and 12 July 2021.

The findings give an estimate of prevalence, broken down by different demographic groups and region, and also give an estimated doubling time and R number.  It also looks at infection rates in vaccinated versus unvaccinated people, with an estimate of infection protection from vaccination.

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 Steven Riley, Professor of Infectious Disease Dynamics, Imperial College London
