Right, so open up once X cohort or X percentage of the population is vaccinated but there is a civic duty to get vaccinated. I know there are always those who can't for medical reasons and won't because they are stupid/paranoid/fell into an internet rabbit hole but those with the physical and intellectual capability to take it should do so.Difficult for private enterprises and the government to police that - and health data is still private data
It's not like people not already meet without masks etc - even in some grocery shops it started to pick up with some staff and customers not using masks.
Also when herd immunity is reached that isn't an issue. It shouldn't be even one when the risk groups are all vaccinated.
