However, little is known about coverage and behavioral correlates among men who have sex with men (MSM) in China. This study assessed self-reported MenB vaccination uptake and its associations with sociodemographic and behavioral factors. Methods: We conducted a nationwide cross-sectional survey among 1022 MSM recruited via community-based organizations and online platforms. Vaccination status and recent sexual behaviors were self-reported. Logistic regression identified correlates of uptake, and latent class analysis (LCA) examined behavioral profiles. Results: Participants had a mean age of 29.6 years; most were unmarried (87.7%) and nearly 90% had a college degree or above. Overall, 21.7% reported receiving MenB vaccination. Uptake was positively associated with condomless anal intercourse (aOR = 1.57, 95% CI: 1.08\u20132.31), group sex (occasionally: aOR = 1.63, 95% CI: 1.01\u20132.64; frequently: aOR = 3.86, 95% CI: 1.85\u20138.04), and female partners in the past six months (aOR = 3.69, 95% CI: 2.25\u20136.10). MSM with multiple casual male partners were less likely to be vaccinated (aOR = 0.55, 95% CI: 0.32\u20130.93). LCA identified heterogeneous subgroups; notably, the \u201cmulti-partner and proactive\u201d group, with high pre-exposure prophylaxis against HIV infection awareness and frequent STI testing, showed low uptake (13.4%). Conclusions: MenB vaccination coverage among MSM in China remained suboptimal. Uptake differed across behavioral subgroups, underscoring the need for stratified, context-specific strategies to inform future vaccine introduction.<\/jats:p>","DOI":"10.3390\/vaccines13090983","type":"journal-article","created":{"date-parts":[[2025,9,19]],"date-time":"2025-09-19T10:08:58Z","timestamp":1758276538000},"page":"983","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Correlates of Meningococcal B Vaccination and Health Behavior Profiles Among MSM in China"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-7575-6411","authenticated-orcid":false,"given":"Rongyan","family":"Li","sequence":"first","affiliation":[{"name":"School of Public Health, Nanjing Medical University, Nanjing 210000, China"},{"name":"University of North Carolina Project-China, Guangzhou 510000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qian","family":"Zou","sequence":"additional","affiliation":[{"name":"School of Public Health, Nanjing Medical University, Nanjing 210000, China"},{"name":"University of North Carolina Project-China, Guangzhou 510000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Zhou","sequence":"additional","affiliation":[{"name":"Zhuhai Center for Disease Control and Prevention, Zhuhai 519000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ye","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Public Health, Nanjing Medical University, Nanjing 210000, China"},{"name":"University of North Carolina Project-China, Guangzhou 510000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dan","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Public Health, Nanjing Medical University, Nanjing 210000, China"},{"name":"University of North Carolina Project-China, Guangzhou 510000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinyuan","family":"Zhang","sequence":"additional","affiliation":[{"name":"University of North Carolina Project-China, Guangzhou 510000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6747-6527","authenticated-orcid":false,"given":"Fengshi","family":"Jing","sequence":"additional","affiliation":[{"name":"University of North Carolina Project-China, Guangzhou 510000, China"},{"name":"Faculty of Data Science, City University of Macau, Taipa, Macao SAR, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Fan","sequence":"additional","affiliation":[{"name":"University of North Carolina Project-China, Guangzhou 510000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xi","family":"He","sequence":"additional","affiliation":[{"name":"Zhuhai Xutong Voluntary Services Center, Zhuhai 519000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9026-707X","authenticated-orcid":false,"given":"Weiming","family":"Tang","sequence":"additional","affiliation":[{"name":"School of Public Health, Nanjing Medical University, Nanjing 210000, China"},{"name":"University of North Carolina Project-China, Guangzhou 510000, China"},{"name":"Dermatology Hospital of Southern Medical University, Guangzhou 510000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"S12","DOI":"10.1016\/j.jadohealth.2016.03.041","article-title":"Deciphering the Burden of Meningococcal Disease: Conventional and Under-recognized Elements","volume":"59","year":"2016","journal-title":"J.
