    In the version of this article initially published, the caption for Figure 5 read “Pope Innocent VIII, likely the first patient to undergo parabiosis.” In fact, he did not undergo parabiosis, but a blood transfusion. The caption should have read “Pope Innocent VIII died in a rejuvenation attempt in 1492.” The errors have been corrected in the HTML and PDF versions of the article.

The error has been corrected in the HTML and PDF versions of the article.
