Will it last years or months? While experts say that only time—and further research—will tell, some are inclined to believe that COVID-19 vaccinations will be a recurring, rather than a one-off, event.

So COVID is going to be with us forever. You KNOW people are going to forget, if they even knew in the first place, to get their annual COVID “vaccine.” Why is this so much more complicated than, say, polio? Polio was a virus, we all got one shot when we were kids and got lifetime immunity. Now, polio has just been about wiped off the face of the earth. Not this fucking thing.

This is another example of those things that make me doubt our competence, like not being able to find MH370. I don’t understand how it is possible to lose a fucking passenger jetliner, and I don’t understand a “vaccine” that requires annual re-administration.
