But a vaccine provides 0 benefit (0 with a capital "Z"), if you've recovered. It's an absolute no brainer that this is the case. If your body wasn't capable of learning an immune resistance from actually having the virus, then vaccines wouldn't work. When public health figures claim that recovered should get vaccinated anyway, even though it goes against theory, empirical data, and clinical trial data, you have to question their credibility. Then you look at their dissolution of the placebo control group. Then you look at their decision to stop tracking breakthrough cases. None of this is acceptable. One must have high standards.
When you have an idea in engineering and you think it's amazing, you have to keep measuring and questioning that. If your data shows that it's not as amazing as you claim, the solution isn't to hide evidence, it's to keep going, keep measuring, and try harder.
