DOD study raises tantalizing question: does flu shot increase vulnerability to coronaviruses?
Hell does the flu shot protect you against the flu?
It has proven to be less than effective because it is not known which variation they are combating.
I always found it interesting that my boss, who always got a flu shot, was invariably sick most of the winter with upper respiratory infection after upper respiratory infection.
I never got the flu shot and oddly enough, after i began taking D3 supplements never got any URI’s.
