Easy......He knows how they operate.....anybody that thinks had to know what they were up to. They did the same thing with regular flu shots.....every year the hospital would make my ex wife take the flu shot for work. The box said only 40% effective but you have to figure they're lying about that. So 20%. Plus how would they know in advance which flu variant was going around next year. Total bullshit. But good money for doctors and hospitals...It's never really about your health but it's about complying with the system that rewards you with lucrative business....
