Tailored messages based on parents' HPV vaccine hesitancy and perceived barriers to vaccination.
Standard (untailored) messages about HPV vaccination reminder/recall.
Messages will be individually tailored to parents' responses to a baseline survey (child gender, vaccination status) and real-time responses to interactive prompts about vaccine hesitancy determinants with links to additional information (e.g., CDC, NJ Department of Health) and community resources to overcome barriers.
Generic reminder/recall HPV vaccination messages.
