Depending on which country you look at you got different goals. Some tried isolation. Others tried herd immunity. We are currently trying those 2 dose vaccines and are already planning for a third before the winter has even started, and I suspect we will see talk about a forth dose by early spring. Then we have nations like Norway addressing covid as a new aspect of the seasonal flue with no end date. The idea that we just take two doses and are done is clearly no longer the goalpost.
