Abbreviations: SpO2: blood oxygen saturation levels; CRP: C-reactive protein; ALT: alanine aminotransferase; AST: aspartate aminotransferase; LDH: lactate dehydrogenase; IL-6: Interleukin 6. P-values compared vaccinated patients and control group, obtained from the Chi-Square test, Fisher’s exact test, or Mann–Whitney U test. Data were presented as n (%) or median [Interquartile range 25–75] unless otherwise noted. Bold indicates statistically significant associations (p < 0.05).
