This study focuses on psychological factors influencing HZ vaccination attitudes and intentions among older adults who have not yet received the HZ vaccine in China. Methods: We conducted a cross-sectional survey of 12,357 older adults (aged \u226560 years) who had not previously received the HZ vaccine. Latent Profile Analysis (LPA) was performed using the 5C psychological antecedents of vaccination (Confidence, Constraints, Calculation, Complacency, and Collective Responsibility). Multinomial logistic regression and Chi-square tests were used to identify predictors of profile membership and to investigate the nature of reported barriers. Results: An optimal five-profile solution was identified, with the largest group being \u201cWilling but Obstructed\u201d (44.6%). This profile exhibited high vaccination willingness but perceived the most significant constraints. While household income was not a direct predictor of profile membership, low-income individuals were significantly more likely to report \u2018high cost\u2019 as a primary barrier (p &lt; 0.01), revealing that socioeconomic status appears to influence vaccination intention through tangible structural obstacles. Conclusions: Vaccination attitudes among previously unvaccinated older adults are heterogeneous. A substantial proportion are willing to be vaccinated but are hindered by socioeconomic barriers, primarily cost. Addressing the intention\u2013behavior gap may require a shift from universal messaging to equity-focused interventions that directly address structural barriers for vulnerable groups, particularly among those who have not yet initiated vaccination.<\/jats:p>","DOI":"10.3390\/vaccines14040331","type":"journal-article","created":{"date-parts":[[2026,4,8]],"date-time":"2026-04-08T09:49:44Z","timestamp":1775641784000},"page":"331","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Profiles of Hesitancy Toward the Herpes Zoster Vaccine Among Older Adults in China: A Latent Profile Analysis"],"prefix":"10.3390","volume":"14","author":[{"given":"Jianing","family":"Dai","sequence":"first","affiliation":[{"name":"School of Health Policy and Management, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100080, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuanruo","family":"Xie","sequence":"additional","affiliation":[{"name":"Department of Health Policy and Management, Mailman School of Public Health, Columbia University, New York, NY 10027, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuxing","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Health Policy and Management, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100080, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuai","family":"Yuan","sequence":"additional","affiliation":[{"name":"Department of Health Policy and Management, Bloomberg School of Public Health, Johns Hopkins University, Baltimore, MD 21218, USA"},{"name":"Institute for Hospital Management, Tsinghua University, Shenzhen 518055, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ling","family":"Zhu","sequence":"additional","affiliation":[{"name":"ChongQing Nanan District Center for Disease Control and Prevention, Chongqing 400060, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiang","family":"Zeng","sequence":"additional","affiliation":[{"name":"Shenzhen Nanshan District Health Committee, Shenzhen 518052, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gang","family":"Liu","sequence":"additional","affiliation":[{"name":"Shenzhen Center for Disease Prevention and Control, Shenzhen 518055, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lili","family":"You","sequence":"additional","affiliation":[{"name":"School of Health Policy and Management, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100080, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhujiazi","family":"Zhang","sequence":"additional","affiliation":[{"name":"Beijing Key Laboratory of Surveillance, Early Warning and Pathogen Research on Emerging Infectious Diseases, Beijing Center for Disease Prevention and Control, Beijing 100013, China"},{"name":"Beijing Research Center for Respiratory Infectious Diseases, Beijing 100013, China"},{"name":"School of Public Health, Capital Medical University, Beijing 100069, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Li, Y., An, Z., Yin, D., Liu, Y., Huang, Z., Xu, J., Ma, Y., Tu, Q., Li, Q., and Wang, H.
