Multivariable logistic regression model was used to investigate independent factors that influence hospitalization. Significant associations are highlighted. Overall test model: p<0.001, R²=43.8%.

*complete scheme (two or more injections of an mRNA vaccine, one or more injection of Janssen vaccine).

CI, confidence interval; IFN-γ, interferon-gamma. Bold value = p > 0.05.
