This is why countries and public health departments are discussing and agreeing on who gets a vaccination first - people in care homes, front-line health workers, or perhaps even young, healthy people because they heavily drive the spread. I don't think there's a situation anywhere where it's a free-for-all. Personally, I will take the vaccine as soon as it's made available to me. Even if my risk is perhaps low (which may or may not be true), taking the vaccine reduces the chance that I would spread COVID to someone else. It's a collective effort to reduce the spread, not an individual or selfish one.
