No vaccine is always "100%". What it does do even if you don't mount a great response to it is to greatly reduce the severity of disease. I should have said that anybody dying of the virus has nobody to blame but themselves. That said, in animals Corona virus vaccines tend to be very effective. This one should be no different in humans. This vaccine is not a guess at trying to predict which strain of influenza is going to hit any given flu season. This vaccine is built specifically for this one virus which is not likely to change enough in my lifetime to necessitate a new vaccine. A different Corona virus might pop up some time and more than likely it will originate in China again just as SARS did.How do we know the COVID vaccine will work 100%..
They have trouble getting the flu vaccine right every flu season..
