I am curious why they didn’t test everyone. Is it just a cost/test capacity thing? Wouldn’t testing to catch asymptomatic cases increase statistical power to allow the study to yield results sooner with smaller error bars? Also, isn’t preventing asymptomatic cases an important function of the vaccine (to get to herd immunity)?
