So far this thread I've given you
1. A real world clinical trial showing vaccine effectiveness
2. A meta-analysis validating the diagnostic instrument used in that trial
3. The consensus position from the authority on infectious diseases.

You've given "scientists have lied before!!!" as a blanket rejection of any main stream research. The odds of SO MANY researchers fraudulently creating such similar results is ASTRONOMICALLY small. That's why we have peer review and additional studies that recreate and verify results.
