Young adults\u2019 attitude to vaccination remains under investigation, although herd immunity cannot be reached without them. The HEalth in Students during the Corona pandemic study (HES-C) provided the opportunity to investigate vaccination intention in 1478 students in the sixth survey wave (January 2021), including vaccination intention, psychological antecedents of vaccine hesitancy, trust in government\u2019s vaccination strategy, and vaccination history. Associations with vaccination intention were analyzed with multivariate ordinal regression and predicted margins were calculated adjusting for gender, age, anxiety, health profession, and subjective health status. A third was decided (yes 25.1%, no 7.6%), and 68% were unsure about getting the COVID-19 vaccine when available. Next to demographic characteristics, vaccination history (influenza vaccination OR = 1.39; 95% CI: 1.06\u20131.83, travel vaccination OR = 1.29; 95% CI: 1.04\u20131.60), trust in vaccination strategy (OR = 2.40; 95% CI: 1.89\u20133.05), and 5C dimensions were associated with vaccination intention: confidence (OR = 2.52; 95% CI: 2.09\u20133.03), complacency (OR = 0.79; 95% CI: 0.66\u20130.96), calculation (OR = 0.79; 95% CI: 0.70\u20130.89), constraints (OR = 1.18; 95% CI: 0.99\u20131.41), and collective responsibility (OR = 4.47; 95% CI: 3.69\u20135.40). Addressing psychological antecedents and strengthening trust in official strategies through targeted campaigns and interventions may increase decisiveness and result in higher vaccination rates.<\/jats:p>","DOI":"10.3390\/ijerph18179210","type":"journal-article","created":{"date-parts":[[2021,8,31]],"date-time":"2021-08-31T21:59:45Z","timestamp":1630447185000},"page":"9210","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["To Vaccinate or Not to Vaccinate\u2014This Is the Question among Swiss University Students"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9003-2027","authenticated-orcid":false,"given":"Julia","family":"Dratva","sequence":"first","affiliation":[{"name":"Institute of Health Sciences, ZHAW Zurich University of Applied Sciences, Katharina-Sulzer-Platz 9, 8401 Winterthur, Switzerland"},{"name":"Medical Faculty, University of Basel, Klingelbergstrasse 61, 4056 Basel, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6683-5671","authenticated-orcid":false,"given":"Aylin","family":"Wagner","sequence":"additional","affiliation":[{"name":"Institute of Health Sciences, ZHAW Zurich University of Applied Sciences, Katharina-Sulzer-Platz 9, 8401 Winterthur, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9871-5324","authenticated-orcid":false,"given":"Annina","family":"Zysset","sequence":"additional","affiliation":[{"name":"Institute of Health Sciences, ZHAW Zurich University of Applied Sciences, Katharina-Sulzer-Platz 9, 8401 Winterthur, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1490-011X","authenticated-orcid":false,"given":"Thomas","family":"Volken","sequence":"additional","affiliation":[{"name":"Institute of Health Sciences, ZHAW Zurich University of Applied Sciences, Katharina-Sulzer-Platz 9, 8401 Winterthur, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"43","DOI":"10.5802\/crbiol.35","article-title":"SARS-CoV-2 Vaccines, Where Do We Stand?","volume":"344","author":"Fischer","year":"2021","journal-title":"Comptes Rendus Biol."},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Abdulla, Z.A., Al-Bashir, S.M., Al-Salih, N.S., Aldamen, A.A., and Abdulazeez, M.Z.
