In the version of this article initially published, two transcriptional errors were present in the Results subsection “Lower CXCR3+ TFH cell induction is correlated with lower IgG levels in older adults.” Starting from the fifth sentence in the right-hand column on page 84, the values “18,200 (5,845)” and “27,200 (7,850)” have been replaced with “11,400 (12,645)” and “19,000 (16,050),” respectively. In the seventh sentence from the bottom in the left-hand column on page 85, “−0.40” has been corrected to “0.40” as the rs value. The original data published in the corresponding figures (Fig. 2a,e) and source data file were correct and the conclusions of the paper remain unaffected. The errors have been corrected in the HTML and PDF versions of the article.
