There is a pretty clear indication that many countries are opening up too quickly and cases are going up. With wider travel worldwide I think we will have a big problem. At best we will one day have 1 billion first world folks vaccinated, which leaves about 7 billion. I hate to say it, but it seems that many are starting to think that the poor, the elderly, the unvaccinated ... are just going to be *acceptable* colateral (SP?) damage, so that the few can have their fun back.
