Correction: Modelling the effects of quadrivalent Human Papillomavirus (HPV) vaccination in Puerto Rico.

[This corrects the article DOI: 10.1371/journal.pone.0184540.].

There is an error in the third sentence of the second paragraph of the Introduction. The correct sentence is: “In Puerto Rico, cancer was the second leading cause of death by 2010 [8], and cervical cancer accounts for 3.9% of all cancer cases [9].”

There are errors in Table 1. The numbers from the 34%/13% scenario are repeated for the 50%/40% and 80%/64% scenarios. In addition, I the 80%/64% scenario, the years have an inverted order. Please see the corrected Table 1 here.
