I could give you facts and figures, official reports, studies, quotes from scientists and health experts, all of which resoundingly prove that taking the vaccine or booster will lead to better health outcomes, both directly (for you) and indirectly (for others). Plenty of articles published in the past few days outline all of the facts and figures and reasons why people should get a booster, who is helped and who is not. And of course just getting the booster doesn't negatively effect you and all insurance covers it, so the worst case is a wasted trip and 15 minutes.
But you don't want to hear the evidence. You just like this perception you have that the vaccines "don't do anything". So I won't try to correct that perception. But I will ridicule you, judge you, and shame you. Anti-vaxxers deserve contempt because they put people's lives at risk and make lifer harder for the rest of us. People who didn't get a flu shot were garbage people because they got more people sick with the flu, and having the flu sucks. People who don't get a covid shot are even more garbage because the mortality for covid is so much higher, there are uncertain long-term health effects even for healthy young people, and getting covid sucks. I'll talk down to anyone that screws other people over when they could easily avoid it, purely because they prefer to live in denial.
