Interventions are needed to increase low HPV vaccination rates within rural areas in the United States, particularly in the state of Florida, which has the seventh highest number of HPV-related cancers. Florida also ranks low compared to other states in terms of HPV vaccination. Rural-residing parents may benefit from two evidence-based strategies to increase vaccination rates: reminder messages informing and prompting vaccination appointments and mobile clinics to reduce transportation barriers. We sought to identify parental attitudes towards (1) message features that promote rural-residing parents' receptivity to HPV vaccination; (2) parents' acceptability of three reminder message modalities (text, postcard, phone); and (3) implementation factors that promote parents' acceptability of using a mobile clinic for vaccination. We recruited 28 rural-residing parents of 9- to 12-year-old children (unvaccinated for HPV) for focus group and individual interviews and thematically analyzed transcripts. Three features promoted parents' receptivity to HPV vaccination messages: source credibility, specific information coverage, and personalization (name and birthday wishes). Parents most preferred text messages and identified three factors promoting parents' mobile clinic use: convenience and feasibility, trustworthiness, and detailed information. The findings indicate rural-residing parents' acceptability of reminder messages and mobile clinics as well as the importance of trust and feasibility when implementing these evidence-based strategies for rural-residing parents.
