Fig. 3. Hazard ratio of infection by number of immunizing events and weeks since the last immunizing event.
Adjusted hazard ratio (HR) of infection with Omicron SARS-CoV-2 by number of immunizing events, n = 42,144 participants. 4 to 10 weeks after the third immunizing event was the reference group. Data are presented as aHR with 95% confidence intervals, adjusted for age, sex, educational level and medical risk group. Numbers between brackets on the x axis represent weeks since the last immunizing event. Underlying numbers and crude estimates can be found in Data S3.
