I don't give a golly whiz if someone gets Shingles. They want the excruciating pain. So be it. SHINGLES is not a communicable disease. I won't get it if you aren't protected so frankly m'dear I don't give a dam* if you do or don't do. It's your body and your neck and your long term agony. You chose it. You got it.
On the other hand. Refusal to get a vaccine that would protect against jeoparding others and possibly kill them, me among them? It is my business then and so I speak out and ask what the he** is wrong with you?
Do you feel you no responsibiity to them? None? It's your world and get the he** out of your way? That's it?
