Easiest is to use StatXact two independent binomial where you choose the ratio option where you set up the columns to correspond to test and control efficacy.

Dear all,

Does anyone know how to calculate the Confidence Intervals for Vaccine Efficacy with only a 2x2 table data?

I searched online and see this topic is interesting. Does anyone have a copy of this presentation?

Methods for Confidence Intervals for Vaccine Efficacy - Tian Dai, Emory University ; Kerry Go, Sanofi Pasteur ; Fabrice Bailleux, Sanofi Pasteur ; Xiao Geng, Michigan State University ; Andrew Dunning, Sanofi Pasteur ; Huiling Xiong, Sanofi Pasteur

Many Thanks,
