Figure 1.

Number of vaccine hesitancy publications by year, and percent concerning HPV. Note. This figure was modified from previous work by the author [98]. Pubmed was searched for articles published between 2010 and 2021 using the term “vaccine hesitancy”, and the number of papers is plotted against the year (in blue, see left y-axis). A separate search in Pubmed over the same time was conducted using the terms “vaccine hesitancy” AND “HPV”; the percent of “vaccine hesitancy” papers concerning “HPV” was calculated (in orange, see right y-axis).
