(2) Methods: We conducted a cross-sectional study from January 2021 to October 2022 among adults in the United States (US), Chile, China, Switzerland, and Singapore using the Global Healthcare Study on Psoriasis survey. (3) Results: A total of 310 psoriasis patients in the US (98), Chile (32), China (80), Switzerland (39), and Singapore (61) were surveyed. Of these, 248 patients (80.0%) were vaccinated at least once for COVID-19 (Chile: 100%, Singapore: 100%, US: 93.9%, Switzerland: 69.2%, China: 45.0%). Compared with other countries, patients in China were 89% less likely to report at least one COVID-19 vaccination (1 \u2212 0.11 = 0.89; OR 0.11; 95% CI: 0.03\u20130.48), and patients in Switzerland were 80% less likely (1 \u2212 0.20 = 0.80; OR 0.20; 95% CI: 0.05\u20130.79). Compared with patients on biologics, patients on topicals were 10.9 (95% CI: 2.1\u201356.6) times more likely to report at least one COVID-19 vaccination, and patients on oral systemics were 7.2 times more likely (95% CI: 1.6\u201331.6). (4) Conclusions: Country of residence and treatment regimen are associated with different COVID-19 vaccination rates in psoriasis patients.<\/jats:p>","DOI":"10.3390\/life14101297","type":"journal-article","created":{"date-parts":[[2024,10,14]],"date-time":"2024-10-14T04:02:58Z","timestamp":1728878578000},"page":"1297","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Global
