There are some of us, younger folks, who have been at a very low risk from the virus, who have initially been told that we should get vaccinated, to protect the old/weak/people at risk. So we did our part on that. Then, Omicron hit, and we got Covid anyways, and we had little to no symptoms (as expected for us, with or without vaccine), but we were still infectious of course. So the initial objective of protecting other people didn't really pan out, since we could still transmit the virus, probably to a very similar extend to if we had not gotten vaccinated at all.
Now people demand from us that we got the booster shot - for no rational reason: It doesn't help us, since we're not at risk personally. It doesn't help others, since we'll still be infectious. By getting fully vaccinated and having had the infection, we even have more protection than those who have not been infected.[0]
So some people grow suspicious to the shenanigans of politicians and pharma companies. This doesn't mean that we don't believe the vaccine works - it undoubtedly does (for those who are at risk). But there are other factors at play, and it very much seems weird, in what ways we're being indoctrinated to "trust the science" (most stupid phrase of the century by the way - science isn't about trust, but about verification.)
In the end it just very much seems like this is mostly about some business and political people lining their pockets with our money, and that causes us to reject their BS, because they've continuously been moving the goalposts in trying to manipulate us to consume their products.
I'm not trying to pitch a narrative here, I'm just talking about how people in their 20s have experienced this, and how we've been feeling about this - at least those in my social circle.
