Correction to: Nature Genetics https://doi.org/10.1038/s41588-019-0417-8, published online 27 May 2019.

In the version of this article initially published, in the subsection ‘GAS vaccine target variation’ in the Results, the text “The analyses revealed that 2,083 isolates carry the J8.0 allele of the M protein” should have read “The analyses revealed that 37% of the 2,083 isolates carry the J8.0 allele of the M protein.” The error has been corrected in the HTML and PDF versions of the article.
