 The study analyzed 146 audio-recorded clinical encounters between providers, parents, guardians and HPV vaccine-eligible adolescents from May 2015 to March 2017 at eight practices in Northeastern U.S. It found that provider recommendations were associated with vaccination rates, with an indicated recommendation resulting in a higher rate of vaccination compared to an elective or contraindicated presentation. The study also found that parental pre-visit intent to vaccinate was associated with vaccine receipt and the association between vaccine recommendation style and vaccine receipt was most pronounced with undecided parents. Overall, the results suggest that the words used to introduce HPV vaccination have the potential to inform parents' decisions about vaccination. This article was authored by Annie T.
