well.. actually the part of the statement is not scientifically accurate and one can always question.. I mean, all those vaccines which are being tested are in controlled environments and samples are collected locally, so there is still lack of 'The vaccine'.. Other hand, the virus is mutating fast as there are already Indian, African variants, and the way the govt handling the situation is a pure joke, e.g. the gap between 2 Covishield doses were first 15-20 days, then 40-45 days and now you must wait for 90 days! So its a valid question to ask if the vaccine is okay or our govt messing it up!
