Campaigns and initiatives to enhance human papillomavirus (HPV) vaccination rates among teenagers in the United States are urgently needed. Healthcare practitioners play an important role in parents’ HPV vaccination decision-making. The current study examines the secondary effects of a multi-component communication-based intervention designed to improve healthcare professionals’ communication regarding HPV vaccination. Surveys of physicians taking part in a 12-month randomised controlled trial were used to perform the evaluation.

The findings show that the use of communication components led to intervention providers reporting better perceived levels of parental HPV vaccine acceptance than control providers, as well as improved vaccination rates in the intervention group in the main RCT.
