The average proportion of population vaccinated, average proportion of infections caused by each variant, and mean IFR and IHR over fixed periods of time over the duration of rounds 1–13 of REACT-1.

Mean IFR and IHR for each period are compared to a baseline period running from 1 May 2020–7 November 2020. The time-lags between positivity and deaths and hospitalisations used in calculating mean IFR and IHR are the best-fit time-lags from the time-delay models fit to rounds 1–7 of REACT-1. (XLSX)
