bk613: How much longer do we say this?
CASE 1: assume you are one person (say an older one) with a vaccine in a group of unvaccinated (say, college or high-school students). Your chance of meeting a sick person is the same as before, but your risk ~ 10-20 lower than before the vaccine. If you remove mask and SD and start partying, you easily increase your risk back to the one that was before you had the vaccine.
CASE 2: you and almost everyone in your environment is vaccinated (like in Israel now, not counting children). Then, transmission decreases in the whole group. Your chance to meet a sick person decreases (in Israel it is now 50x less cases than at peak 4 months ago) + your own 10x lower risk, this is making a difference.
CASE 3: reality is somewhere in between if you live around many non-vaccinated people …
and uncertain future given that the virus continues going thru millions of people worldwide and mutating on the way.
but at the end the question is childish: some people are expecting some servants to tell them to take the masks of because they are inconvenienced. I think, it is more about a public emergency
and what you can do to help. Not just you personally having a mask, but can you help an elderly person so that he does not need to go to a store, or organize young people so that they do not have to mix with hundreds of others, or shlep to another side of the world to learn. Such an easy opportunity to do so many mitzvos.
