Your problem is you make bullshit claims that immunity is not stopping severe disease, which it is. How does that article in any way prove severe disease is not being adverted due to immunity but due to boosters, reinfection, and less severe variant? Ever think these variants are less severe because covid isn't a novel virus anymore (our immune systems know it) vs the variant being less severe? It's kinda hard to study people that have never seen the virus or never been vaccinated at this point.Your problem, as always, is identifying one aspect and then hyper-focusing on it.
Vaccine protection derives from antibodies, B-cells, and T-cells. Some wane faster than others, and B-cells wane relatively slowly (though wane they do). And so, since it's useful for your position, you'll focus on them as if they're solely the important ones, and write off antibodies which wane much quicker.
No, that ain't how it works. Vaccines achieve their level of protection from all 3.
COVID vaccine immunity is waning — how much does that matter?
As debates about booster shots heat up, what’s known about the duration of vaccine-based immunity is still evolving.www.nature.com
Feel free to read the posts which have already laid out my positions if you'd like to address them.
You never outlined your plan, you just give snippets here and there. You mention using vaccines can slow infections shortly after being given but don't say how to use this in any meaningful way. I even listed in the most ideal way of doing that, you wouldn't be accomplishing anything anyway. You mention contact tracing but that's not possible to be done regardless if we squashed covid to near 0 or it's all over the place, it's not a virus that can be contact traced in any effective manner.
