Fig. 3: Subgroup analysis. SARS-CoV-2 reinfection risk, stratified by vaccination status.
From: Immune histories and natural infection protection during the omicron era
Hazard ratios for the incidence of SARS-CoV-2 reinfection in the studies comparing the incidence of SARS-CoV-2 reinfection between a the omicron double-infection cohort and the omicron single-infection cohort, b the omicron double-infection cohort and the pre-omicron-omicron double-infection cohort, and c the pre-omicron-omicron double-infection cohort and the omicron single-infection cohort. Error bars indicate the corresponding 95% confidence intervals.
