I've asked this numerous folks and searched myself... find me proof that the flu is contagious.

they changed how they diagnosed the whooping cough after introducing the vaccine.

sanitation and hygiene are the real heroes.

some intelligent but evil people road the wave of assumption.

I get the feeling it is time that wave crashed and people woke up to the reality of their own creation and stop following insanely greedy and selfish and horrible people that seek to enrich themselves at their expense.
