How doesn't it work?
Do you think a vaccine has to be 100% effective to "work"?
The federal govt shut down the swine flu injection in the 1970s after seven people died. That's when they had a shred if decency, morality, and a tad bit less corrupted. Fast forward 45 years, thousands dead in preliminary trials, hundred thousands to millions dead from the injection in experimental phase and nary a peep from our corrupt, despicable govt about shutting it down. Simply abhorrent.
