The common sense so far has been, that infectious(of any infections - not only covid, which is the worst of the inffection type - as it is airborne infection) people should not walk around and stay at home until they get through their infection. With covid, the issue is that it is not causing any symptoms in most cases and it can stay in organism for months - also without any symptoms. So, esentially any covid infected - vaccinated or not should avoid other people for ~1year, to be really sure that covid is gone.
Also, let's look on this from different perspective - people that has to be protected from covid are minority - ~10% at max. Among them there are higher chance that they will die from complications just from vaccines, so you might think, that by getting vaccine you might be protecting others, but I assure you - the best help that you can do is by not contacting other people, especially vulnerable people. So far, the main narrative is that vaccination helps and they happily go around and infect others - even with new strains... so, the end result is equally stupid.
