Impact of different intervention policies on pandemic severity for three considered variants simulated for two census years (top row: 2016; middle row: 2021; bottom row: relative change between years). Each column compares the impact of five intervention policies for one variant of concern: a ancestral; b Delta; c Omicron. See Fig. 2 for a detailed description of the considered intervention policies. Coloured shaded areas around solid lines show standard deviation. Each profile corresponds to one intervention policy and is computed as the average over 100 runs
