This is obviously a kind of time-machine satire. The unvaxxed were simply skeptical that the vaccines were sufficiently tested and validated to risk getting the jab.
Major studies done by the state of Texas showed that the vaccines were really only beneficial to people over 50 in preventing hospitalization and death. Younger cohorts were exposed to the risks of myocarditis and blood clots from the mRNA without seeing significant reduction in their rate of hospitalization and death from COVID compared to the unvaxxed.
Yea, I was just being Snarky. Sadly, the data is now so corrupted that the truth may never be known.
