As your article notes, Russia was similar to allowing people to join the phase 3 trial. It was not a widespread deployment of vaccines and was not analogous to the EUA for Pfizer and moderna. “In effect, Russia will be conducting its Phase 3 trials live, treating it more as a demonstrator group than a control group meant to ensure there is nothing dangerous awaiting the larger population.
