They don't release more details officially due to patient confidentiality, but the unofficial word was that a young doctor treating COVID patients died of COVID during the trial, but was in the control group and did not receive the vaccine. It is very sad whenever a doctor dies trying to save others, but especially because they may still be alive if they had been randomized to the vaccination group (of course we don't know that for sure though, since the vaccine may still prove to be effective or ineffective).
