I'm starting to think 100% vaccination is a weird goal. There have been examples of drugs that only caused issues years after taking it. Thalidomide (called "Neurosedyn" in Sweden) is one. Even if issues arise right away, it may take years to gather statistical data to agree on the risk factors. In the meantime, to any one doctor, it may look random. Injecting every person on Earth with one of only a few, new, vaccines seems dangerous. This has me wondering about two things: 1) Isn't it good to have an unvaccinated control group? 5-10%? Not just based on people who for some reason cannot take any vaccine, but healthy individuals. 2) Shouldn't we only use a single vaccine for every dose per person? To narrow the population affected by potential unknown side-effects. Has anyone heard any officials/domain experts discuss this? (I'm not against vaccination per se, and am myself on the third dose already. I'm just worried we're blinded by one danger, and willingly heading into another.)
