Correction to: Nature Immunology https://doi.org/10.1038/s41590-023-01739-z, published online 15 January 2024.

In the version of the article initially published, in the “BCG-induced CX3CR1hi T cells are effector memory T cells” section, the first five callouts to Fig. 3 erroneously cited Fig. 2. This has now been amended in the HTML and PDF versions of the article.
