PURPOSE: The purpose of the study was to explore parents' attitudes and beliefs about the nine-valent @entity1082 vaccine (HPV9). METHODS: Online focus groups were conducted in January, 2015. The U.S. national sample of parents was recruited to four groups: (1) two groups of parents of HPV unvaccinated daughters aged 9-12 years and (2) two groups of parents of vaccinated daughters aged 11-17 years. RESULTS: @entity1 were 43 parents of vaccinated daughters and 38 parents of unvaccinated daughters. Results indicated low and variable levels of knowledge about HPV, related @entity5 , and vaccination (e.g., parents unaware vaccine is recommended for @entity1 ). Parents were encouraged that HPV9 covered more types, and many said they want the "better" vaccine. Parents of unvaccinated @entity1 wondered whether they should delay vaccination until HPV9 was available, whereas parents of vaccinated @entity1 wondered whether their daughters could be revaccinated with HPV9. Concerns were related to adverse reactions and side effects, whether another new vaccine will be released after HPV9, HPV mutation (i.e., will HPV types change over time-thereby necessitating multiple vaccines?), and cost. Physician recommendation was identified as the most important facilitator of vaccination, with @entity1 wanting providers to exhibit high levels of confidence in and knowledge about HPV vaccines. Last, parents also viewed the prospective idea of a 2-dose HPV9 vaccine as positive. CONCLUSIONS: HPV9 recently became available in the United States and has the potential to offer greater @entity5 prevention if widespread acceptance and uptake occur. Understanding parental perceptions and questions about HPV9 will be important for clinical messaging about this vaccine.
