To analyze the frequency of influenza and SARS-CoV-2 co-infections, as well as the differences in the course of disease (risk of mortality, hospital and intensive care admissions) in patients infected with the SARS-CoV-2 virus in relation to flu vaccination status in the 2021-2022 season. Methodology. Population-based observational retrospective study in a cohort of 19,850 patients diagnosed with COVID-19 between June 1, 2021 and February 28, 2022 on the island of Gran Canaria. Results. A total of 1,789 patients (9%) diagnosed with COVID-19 had received flu vaccinations. 13,676 people (68.9%) had a full course of COVID-19 vaccinations. In the period between June 1, 2021 and February 28, 2022, 8 cases of flu and COVID-19 coinfection were recorded. Hypertension (18.5%), asthma (12.8%) and diabetes (7.2%) were the most frequent comorbidities. There were 147 deaths (0.7%). Older patients ([OR] 1.11 95% CI 1.09-1.13) and people with cancer ([OR] 4.21 95% CI 2.58-6.89) had a higher risk of dying from COVID-19 (p&lt;0.05). Female sex was noted as a protective factor ([OR] 0.61 95% CI 0.40-0.92). Conclusions. Old age, male sex and cancer were independent prognostic factors for mortality. Three doses of SARS-CoV-2 vaccines and influenza vaccines were highly effective in preventing COVID-19-related deaths and hospital admissions. These findings suggest that flu vaccination can help control the pandemic.<\/jats:p>","DOI":"10.37201\/req\/102.2022","type":"journal-article","created":{"date-parts":[[2023,1,27]],"date-time":"2023-01-27T09:37:56Z","timestamp":1674812276000},"page":"180-186","source":"Crossref","is-referenced-by-count":0,"title":["Epidemiological study on the impact of influenza vaccination on the clinical course of patients with COVID-19 and co-infection by both viruses in Gran Canaria, Spain"],"prefix":"10.37201","volume":"36","author":[{"given":"Jos\u00e9 Luis","family":"Alonso Bilbao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alejandro","family":"de Arriba Fern\u00e1ndez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alberto","family":"Espi\u00f1eira Franc\u00e9s","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio","family":"Cabeza Mora","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00c1ngela","family":"Guti\u00e9rrez P\u00e9rez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miguel \u00c1ngel","family":"D\u00edaz Barreiros","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"23328","published-online":{"date-parts":[[2023,1,27]]},"container-title":["Revista Espa\u00f1ola de Quimioterapia"],"original-title":["Estudio epidemiol\u00f3gico sobre el impacto de la vacunaci\u00f3n antigripal en la evoluci\u00f3n cl\u00ednica de pacientes con COVID-19 y la coinfecci\u00f3n por ambos virus en Gran Canaria, Espa\u00f1a"],"deposited":{"date-parts":[[2023,3,11]],"date-time":"2023-03-11T12:20:36Z","timestamp":1678537236000},"score":1,"resource":{"primary":{"URL":"https:\/\/seq.es\/abstract\/rev-esp-quimioter-2023-january-27-2\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,1,27]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2023,3,10]]},"published-print":{"date-parts":[[2023,3,10]]}},"URL":"https:\/\/doi.org\/10.37201\/req\/102.2022","relation":{},"ISSN":["0214-3429","1988-9518"],"issn-type":[{"value":"0214-3429","type":"print"},{"value":"1988-9518","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,1,27]]}}}
