It could also be that the older a vaxxee is, the more susceptible they are to the short-term dangerous effects. If this is some kind of deliberate conspiracy, one argument against that might be is, why would the system implement something more likely to kill and maim the people who support and trust it, while leaving those who do neither alive and healthy? One answer to that question might be is that the agenda of culling the population through vaccine-deaths and reduced birth-rates, takes precedence over everything else. So if loyal normies have to be killed or possibly made burdens on society through being rendered disabled by the vaxx if it doesn't kill them, then so be it. And if that is the deliberate agenda, we can be sure these vaccines will result in lower population numbers. That really would be a slow-motion apocalypse.
