Correction to: Nature Reviews Immunology https://doi.org/10.1038/s41577-023-00904-7, published online 11 July 2023.

Since publication of this article, the second sentence of the legend for Figure 1, describing a change in data collection at the Office of National Statistics, has been clarified to read “The Office of National Statistics (ONS) moved from interviews in person to online only data collection in the autumn of 2022. ONS estimated that online only reporting gives estimates 1.3 × higher than in person, and so the yellow squares correspond to estimates adjusted downwards to be comparable to previous reporting practice”. In Table 3, the names of the drugs “Leronlimab” and “Rintatolimod” were originally misspelt, and the “Rationale” column for the row beginning “Temelimab” now reads “Anti-HERV-W Env”. These changes have been made to the HTML and PDF versions of the article.
