The flu vaccine is just not relevant to this virus.
Yes I know. But if the flu vaccine given for seasonal flu prevented some deaths, then the CV19 10 times fatality rate is flawed.
If we had no seasonal flu vaccine, then I suspect that number would be higher, resulting in less than a 10x factor.
CV19 did not have the benefit of having an immunization available.
