Figure 4: Proportion of persons that are protected against COVID-19 disease over time after second vaccination in the total group by age group and by comorbidity status.
A person is considered to be protected against COVID-19 if the SARS-CoV-2 S1 reactive T-cell test is positive, i.e. >200 mIU/ml, and the neutralisation capacity is >75%. Dots and crosses indicate the individual protection status (0%=not protected, 100%=protected), the line indicates the predicted proportion and the grey area indicates the 95% prediction band.
