In USA, the numbers are better than some might think. We have had 23 million "test-confirmed" cases of Covid-19. The best guess is that for each person who tested positive, there are between 5 and 10 people who have been infected, but didn't know it, or for whatever reason, were not tested. So, as of now, we have somewhere between 100 and 200 million in USA who have been infected and have the immunity that results from surviving an infection.
If we need to have 70% immunity in the population in order for herd immunity to do its thing, the target is 230 million. We're either not far from that (or, in the worst case, more than 1/2 way there). We're adding vaccinated individuals and infected but recovered individuals every day. So, I think we'll get to herd immunity (which makes this less of a public health issue and more of an individual health issue) before too much longer.
However, I don't know what it will take to have countries and companies and individuals all conclude that its safe to travel and therefore resume scheduling the sorts of things like overseas bicycle trips that we had before 2020. That may actually be 2022. .
