Relative Vaccine Efficacies in a Simulated PCV13 Trial. a Relative VE determined using prevalences. b Relative VE determined using prevalence odds. In both sub-figures, the “calculated” relative VE was determined from the initial VE parameters of the simulation according to the formula: Relative VE = 1 – (1 – VEintervention)/(1 – VEreference)
