Last I checked only about 50% of people ever get the flu shot routinely. And isn't the idea of flu shot that it prevents symptomatic infection? The whole reason why people get the flu shot is they don't want to get the flu. Covid vaccine doesn't stop symptoms the same way.

I don't recall it ever being sold to me as that, and though I regularly get them, I've never gotten a flu shot with that expectation. It reduces your odds and makes the thing more mild. That's the point. That's what I've been told my whole life. They're not magic solutions to everything in your life, they can't even be 100% sure about how to tweak them for the dominant strains that season, but they help.

This stuff makes people go a little crazy with unreasonable expectations. I remember people complaining in pre-pandemic years ... "the flu shot is only x% effective so why bother?" And the reason has always been that x > 0, any two-digit number for x is pretty worth it, even if it intuitively sounds small. It's pretty similar for COVID.
