yes, given that the probability of getting infected for vaccinated people is about third of that of unvaccinated, and once infected vaccinated spread the virus the same as unvaccinated (discussed at length with the links for example here https://news.ycombinator.com/item?id=28066844), forcing vaccine upon low risk groups starts to looks like an immoral thing as it does nothing to prevent the spread (roughly speaking the Delta's R0 for vaccinated is the third of Delta's R0 for unvaccinated, i.e it is like the R0 of the original).
