Yeah, we actually do that. Here's the Phase III trial for Pfizer's vaccine where they did a RCT of 43,000 people. They published their efficacy and safety end points (as well as criteria for stopping the trial if they found safety issues) before enrollment and show the results as well. They're following the same patients for two years to assess long-term safety as well: https://www.nejm.org/doi/pdf/10.1056/NEJMoa2034577?articleTo... |
