Maybe if you understood a bit about vaccines you'd already know the answer to that question. Since you don't: vaccines are not either 100% effective or 0% effective, they are somewhere in between. I'm vaxxed so I have some protection, even though I might still get a case. If you're vaxxed, I have even more protection since it is less likely you'll pass it on to me.If you're vaxxed then it's no concern of your's if others are not. Unless you know vaccines are not working. In that case why bother?
