Honest question: why does this matter to you? The vaccine doesn't stop transmission, that's widely acknowledged now, and can't establish herd immunity (unless you plan to vaccinate deer).

It doesn't affect you at all so why waste time thinking about others' cost-benefit analysis?

We all have our reasons. They're all unique and inevitably personal. For my part, standing my ground and resisting the pressure to get jabbed is one of my proudest achievements.
