Between 29 June 17 August 2023, we conducted a cross-sectional survey gain insights about barriers facilitators 2011 18 45 years Tennessee. We developed our based on previous instruments...
Despite evidence-based recommendations for HPV vaccination, uptake among young adults is suboptimal. Limited research has explored factors that may influence vaccination adults, as well associated promotion and informational preferences in this group. This study aimed to examine with vaccine information promotion.
Background: Human papillomavirus (HPV) remains the most prevalent sexually transmitted infection in United States (U.S.). By age of 45, over 80% Americans will contract HPV, which creates a significant public health concern. Despite availability effective vaccines, low vaccination uptake continues to be challenge, particularly Tennessee. Additionally, Advisory Committee on Immunization Practices (ACIP) recently expanded recommendations for HPV vaccine usage include adults aged 27–45,...
