Quality over quantity: human papillomavirus vaccine information on social media and associations with adult and child vaccination

Abstract

Human Papillomavirus (HPV) vaccination is recommended for adults aged 27–45 as a shared clinical decision with their healthcare provider. With the rise of social media as a vaccine information source, this study examined the extent of exposure to HPV vaccine content by social media platform and evaluated associations between HPV vaccine content on social media and HPV vaccine intent among both 27–45 year olds and their eligible children. U.S. participants (51% women, 9% Black, 8% Hispanic/Latinx), aged 27–45, were cross-sectionally surveyed online from April to May 2020 (n = 691). Outcomes included HPV vaccination intention (intend/do not intend) for themselves and, among participants with unvaccinated children aged 9–17 (n = 223), their eligible children. Adjusted odds ratios for HPV vaccine content and both outcomes were calculated. Extent of HPV vaccination exposure on social media was not associated with intention to vaccinate for HPV. Seeing mostly negative/mixed information about the HPV vaccine on social media was associated with lower odds of vaccination intention for adults (aOR = 0.34, 95% CI 0.15, 0.79) and adolescents (aOR = 0.34, 95% CI 0.21, 0.53). Viewing HPV vaccine information from social media as not credible was associated with lower odds of vaccine intent for adults (aOR = 0.17, 95% CI 0.07, 0.41) and adolescents (aOR = 0.16, 95% CI 0.10, 0.29). Although extent of HPV vaccine exposure on social media was not associated with vaccination outcomes, findings support developing quality social media strategies that increase the dissemination of positive and credible information in favor of HPV vaccination.
