There is a growing anti-vaccine concern that may affect the success of the fight against the SARS-CoV2 pandemic. To evaluate opinions and attitudes toward vaccination, we conducted an anonymous online survey among Polish patients diagnosed with cancer. We analyzed how socio-demographic factors, type of cancer, comorbidities, previous influenza vaccinations, and information sources affect the general willingness and opinions about vaccinations, emphasizing vaccination against COVID-19. Six hundred thirty-five patients (80.2% female) participated in the study. A positive attitude towards vaccination was presented by 73.7%, neutral by 17.8%, while negative by 8.5%. Willingness to get vaccinated was declared by 60.3%, 23.5% were unwilling, and 16.2% were undecided. Significant predictors of willingness were education, marital status, active anti-cancer treatment, previous influenza vaccination, and positive attitude towards vaccinations. Patients with cancer have concerns regarding safety, effectiveness, and the process of development of the COVID-19 vaccine. Overall, patients with cancer present positive attitudes towards COVID-19 vaccination but required sufficient information on its efficacy and side effects.<\/jats:p>","DOI":"10.3390\/vaccines9050411","type":"journal-article","created":{"date-parts":[[2021,4,21]],"date-time":"2021-04-21T21:25:10Z","timestamp":1619040310000},"page":"411","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":73,"title":["Attitudes of Patients with Cancer towards Vaccinations\u2014Results of Online Survey with Special Focus on the Vaccination against COVID-19"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0017-1040","authenticated-orcid":false,"given":"Anna","family":"Brodziak","sequence":"first","affiliation":[{"name":"Laboratory of Centre for Preclinical Research, Department of Experimental and Clinical Physiology, Medical University of Warsaw, 02-097 Warsaw, Poland"},{"name":"Department of Oncology and Radiotherapy, Maria Sklodowska-Curie National Research Institute of Oncology, 02-781 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4799-9611","authenticated-orcid":false,"given":"Dawid","family":"Sigorski","sequence":"additional","affiliation":[{"name":"Department of Oncology, University of Warmia and Mazury in Olsztyn, 11-228 Olsztyn, Poland"},{"name":"Department of Oncology and Immuno-Oncology, Warmian-Masurian Cancer Center of the Ministry of the Interior and Administration\u2019s Hospital, 11-228 Olsztyn, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ma\u0142gorzata","family":"Osmola","sequence":"additional","affiliation":[{"name":"Department of Hematology, Transplantation and Internal Medicine, University Clinical Centre, Medical University of Warsaw, 02-097 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0261-8133","authenticated-orcid":false,"given":"Micha\u0142","family":"Wilk","sequence":"additional","affiliation":[{"name":"Centre of Postgraduate Medical Education, Department of Oncology, European Health Centre, 05-400 Otwock, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angelika","family":"Gawlik-Urban","sequence":"additional","affiliation":[{"name":"Department of Clinical Oncology, Maria Sklodowska-Curie National Research Institute of Oncology, 31-115 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joanna","family":"Kiszka","sequence":"additional","affiliation":[{"name":"Subcarpathian Cancer Center, 35-055 Rzeszow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5320-9321","authenticated-orcid":false,"given":"Katarzyna","family":"Machulska-Ciuraj","sequence":"additional","affiliation":[{"name":"Department of Clinical Oncology, Saint John of Dukla Oncology Centre of the Lublin Region, 20-090 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4103-1626","authenticated-orcid":false,"given":"Pawe\u0142","family":"Sobczuk","sequence":"additional","affiliation":[{"name":"Laboratory of Centre for Preclinical Research, Department of Experimental and Clinical Physiology, Medical University of Warsaw, 02-097 Warsaw, Poland"},{"name":"Department of Soft Tissue\/Bone Sarcoma and Melanoma, Maria Sklodowska-Curie National Research Institute of Oncology, 02-781 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"176","DOI":"10.1016\/j.amjmed.2020.08.019","article-title":"History of the Plague: An Ancient Pandemic for the Age of COVID-19","volume":"134","author":"Glatter","year":"2021","journal-title":"Am.
