The big misunderstanding with the vaccines is that they prevent or reduce significance of the disease Covid-19. What was, very intentionally, taken for granted was that preventing the disease would thus prevent the transmission of the pathogen SARS‑CoV‑2 and thus stop the Covid-19 epidemic.
With that said, COVID-19 is an incredibly versatile disease that can affect every organ in your body including your brain, immune system, heart etc. Getting the vaccine and avoiding getting sick is critical to your long term health and while it doesn’t stop transmission it can slow it. Especially when combined with other tools, like masks, quarantining, etc.

That is not the case and it was known back in 2022. Herd immunity was never possible with it.
