Correction to: Nature Immunology https://doi.org/10.1038/s41590-023-01497-y, published 27 April 2023.

In the version of this article initially published, there was a typo in the y-axis in the Fig. 4f graph, where “CD27APC-Cy7” originally read “CD21APC-Cy7”. This has been corrected in the HTML and PDF versions of the article.
