AIIMS Director, Dr Randeep Guleria, tells NDTV that "our numbers are not that bad if we look at cases per million population. But we really need to work hard to see where these cases are coming from." He also says, "It is difficult to have a vaccination in 45 days. Processes need to be followed in Phase 1,2 and 3 trials and these themselves take time. When we are giving a vaccine to healthy individuals, it has to be safe and it should not have any side effects."
