Vaccine passports are dumb for this reason. Somebody choosing to be at higher risk does not increase the risk to other other than clogging up hospital resources
Which is significant.
Also, most of these polices were created based on research prior to Delta becoming prevalent which showed that the vaccines indeed did reduce spread. Since Delta is more transmissible, this benefit is reduced.
So it doesn't have an impact except for when it does?
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.
