WebEXAMPLE: Calculating Vaccine Effectiveness. Calculate the vaccine effectiveness from the varicella data in Table 3.13. VE = (42.9 − 11.8) ⁄ 42.9 = 31.1 ⁄ 42.9 = 72%. Alternatively, VE = 1 − RR = 1 − 0.28 = 72%. So, the vaccinated group experienced 72% fewer varicella cases than they would have if they had not been vaccinated.
