    Well no the first polio vaccine, to use your own example, didn’t do that either. Even today it takes 4 shot to reach 99,9

      No amount of covid shots stop you catching or spreading covid.

        Neither did the first polio shot

        It could be 0,1% effective and it would still be called a vaccine
