Coronavirus 2019 disease (COVID-19) continues to affect the World today with over 340 million cases and over 5.5 million deaths. This situation reveals the need for vaccination, given that it is not an effective treatment. Our purpose in this study is to compare the vaccination status of hospitalized patients due to COVID-19 and to investigate their efficacy. The study is a descriptive study and cross-sectional type. The research was carried out by retrospective examination of hospital automation data in Samsun province. In the 4-months period between July 01 and October 31, 2021, patients hospitalized due to COVID-19 were classified according to their vaccination status and identified through descriptive statistical methods. 1174(15.58%) of 7534 COVID-19 patients were admitted to intensive care units (ICU), it was observed that 879(74.8%) of the patients admitted to the ICU were unvaccinated, 174(14.8%) were vaccinated with 2 doses of Sinovac, and 0.08% (n=1) were vaccinated with 2 doses of Biontech reminders on 2 doses of Sinovac. Of the 6360 patients hospitalized in the clinics due to COVID-19, 54.76% (n=3483) were female, and 41.03% (n=2610) were ≥ 65 years old. 49.31% (n=579) of the patients hospitalized in the ICU were women, 72.65% (n= 853) were ≥ 65 years old. Unvaccination increases the risk of hospitalization and ICU admission. Missing a reminder dose and advanced age are high risk factors for hospitalization. About half of those hospitalized and the majority of those admitted to the ICU are unvaccinated, and vaccination reduces hospitalizations.
