Hypothesis testingWe propose some statistical tests for evaluating no matter if and how the vaccine efficacy is dependent upon the marks. The following null hypotheses are examined: H : ; H : ; H : and H : . The null hypothesis H indicates that the RRs usually do not rely on the marks; H implies that the marks v and v do not have interactive effects on RRs; H implies that RRs are certainly not affected by v; while H implies that RRs are not affected by v.

Hypothesis testingWe propose some statistical tests for evaluating whether or not and how the vaccine efficacy is determined by the marks.
