Young Adult Human Papillomavirus and Influenza Vaccine Coverage: A Comparison Across College Enrollment Status.

To determine human papillomavirus and influenza vaccine coverage among young adults in the US and assess differences in vaccine uptake by college enrollment status, we conducted an online survey of young adults aged 18-26 (n = 417) using Survey Monkey, with recruitment occurring through Amazon's Mechanical Turk (MTurk) platform. We collected data on self-reported preventive health behaviors, including vaccine receipt, current college enrollment status, and other demographics. Overall, 49% of participants reported receiving at least one dose of human papillomavirus vaccine and 57% reported receiving at least one influenza vaccine over the past three years. Vaccine coverage estimates did not differ between college-enrolled and non-enrolled respondents. Low vaccine coverage rates demonstrate the need to improve vaccine strategies for young adults. The strongest predictor of vaccine receipt was having received a provider recommendation. There does not appear to be healthcare utilization differences related to ability to access care through student health or community-based settings. Additional research is needed to develop interventions to improve vaccination coverage among young adults, both currently enrolled and not enrolled in college.
