HPV vaccine hesitancy in the United States

Human papillomavirus (HPV) is the most common STI and accounts for roughly 37 000 HPV-associated cancers annually in the United States. Despite documented safety and effectiveness of the HPV vaccine, vaccination rates should be higher. We summarize literature surrounding vaccine hesitancy, a main reason for suboptimal vaccine coverage. We aim to describe the complex factors that lead to hesitancy in order to support improvement of vaccination rates in our communities.

Studies document sustained immunogenicity and effectiveness 10 years post HPV vaccination. Vaccine coverage was rising until 2022, when initiation declined. Primary reasons for hesitancy are: perceived lack of provider recommendation, a lack of parental knowledge and necessity especially if an adolescent is not sexually active, and safety concerns. The COVID-19 pandemic challenged access to care and exacerbated vaccine-related discourse. Studies of hesitant adopters reveal that social processes, including conversations with community members, have a substantial impact on decisions to vaccinate.

We highlight recent literature behind parental hesitancy toward the HPV vaccine, focusing on concerns about its necessity and safety, exacerbated by medical mistrust and misinformation. We summarize findings of successful educational outreach and community-based interventions to improve vaccination rates in the postpandemic social media era.
