The original version of this Article contained several errors in the Abstract, Results, Figures, and Supplementary Information. This occurred because incorrect parameter values were used in the code.

The code linked in the Code availability statement in the Article is correct: https://github.com/mrc-ide/sarscov2-severity-england. The previous incorrect version of the code is available at: https://github.com/mrc-ide/sarscov2-severity-england/releases/tag/v1.0.0. The current and previous versions of the code can be compared at: https://github.com/mrc-ide/sarscov2-severity-england/pull/2.

The original version of this Article contained errors in the Abstract and Results:
