Yes, it works for much of the population.

I've personally had 3 full doses, and I can't be sure of my own protection. I'm on medicine that moderately suppresses my immune system, and it is likely that I am not protected.

And I'm one of the lucky ones: Some folks simply can't be vaccinated or simply won't get any protection.

And this isn't even getting into the fact that the folks not getting vaccinated means there are more chances for the virus to change in ways that make the vaccine worthless.

Me - and others - depend on everyone that can get vaccinated to, well, get the freaking vaccine. Not getting the vaccine is putting others at risk. And this is with vaccines working as designed.
