At random days (2019\u20132020), 280 men were included. We collected questionnaire data regarding risk factors for HPV infection and a penile swab for HPV testing. We compared results in this study with those from a previous study of young men (2006\u20132007).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The majority of participants (94%) were 18\u201320 years old. The median number of lifetime sexual partners was 4. Altogether, 130 men (46.4%) were HPV positive. No infections with HPV types 6, 11, 16, 18, 31, and 45 were detected. The most frequent type was HPV-51 (detected in 11.1%). Comparison showed that the odds of high-risk HPV type infection were higher in 2019\u20132020 (prevalence odds ratio [POR], 1.7 [95% confidence interval {CI}, 1.1\u20132.7]) compared with 2006\u20132007. In contrast, the odds were lower (POR, 0.3 [95% CI, .1\u2013.6]) for HPV types targeted by the 9-valent HPV vaccine.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>The multicohort girls-only vaccination program has to a large degree protected young men against the HPV types included in the licensed vaccines.
