Do you have a "obese passport", "health score"? You can't use a logic only when it's convenient. Implementing a health score and precenting unhealthy people (or even old people) from going outside would alievate hospital use. Do we want that?

Although the vaccine seems to somewhat lessen the chance of transmission, it IMO is not enough to stomp on people's freedom. I would maybe consider it if it was the black plague.
