				        	Objective:To analyze the clinical characteristics of patients inoculated with different vaccines and underlying diseases, infected with the novel coronavirus Omicron variant.Methods:The data of 430 patients infected with the novel coronavirus Omicron variant who were admitted to Tianjin First Center Hospital from January 21, 2022 to March 7, 2022 were collected. A total of 108 patients with Omicron variant infection with underlying diseases were selected and enrolled. The gender, age, body mass index (BMI), history of underlying diseases, vaccination status (vaccination times, vaccination type), clinical symptoms, laboratory test indicators, imaging data, hospitalization time, nucleic acid negative conversion time, re-positivity and antibody titer from the two groups of the patients were collected and analyzed.Results:In the 108 patients, 93 cases received inactivated vaccine and 15 cases received adenovirus vaccine. There was no statistically significant difference between the two groups in terms of gender, age, BMI, disease types, whether completed the fully vaccinated, whether had prime boost and underlying diseases. Both groups had fever, dry cough, sore throat, runny nose and other clinical symptoms, but there were no statistical difference between the two groups. There were no statistically significant differences in laboratory blood routine tests, biochemical indexes, C-reactive protein (CRP) level and the results of chest computed tomography (CT) imaging between the two groups. There were no statistically significant differences in hospitalization days, nucleic acid negative conversion time, whether admission to intensive care unit (ICU), turn re-positive on nucleic acid tests and immunoglobulin M (IgM) antibody titer expression between the two groups, but immunoglobulin G (IgG) antibody titer in adenovirus group was higher than that in inactivated group (g/L: 229.67±26.13 vs. 194.33±61.56, P = 0.020). There were also no significant differences in laboratory examinations, hospitalization days, nucleic acid negative conversion time, turn re-positive on nucleic acid tests and Novel coronavirus antibody titers expression of the patients with booster shots between the inactivated vaccine group and the adenovirus vaccine group. Conclusions:The protection of inactivated virus vaccine is equivalent to adenovirus vaccine in patients with underlying disease Omicron variant infection, and the titer of IgG antibody in patients with adenovirus vaccine is higher than that in patients with inactivated virus vaccine after one week of recovery.
