A new vaccine is being tested against disease D in a randomized trial. Assume those who received the vaccine had a disease D incidence of 10 cases per 1,000 population per 3 months, and those received a placebo had a disease D incidence of 60 cases per 1,000 population per 3 months. The disease D incidence in the general population was 45 cases per 1,000 population per 3 months. What is the efficacy (shown as a percent) of the vaccine based on this study?
