That's what I was thinking and it was a ray of hope and maybe even the rational thing to expect. But we now have vaccines they had not. Is the loss of advantages (if they are) like different population density and spread, travel, nutrition, etc. compensated by our vaccines so that we can hope for the same ending ? I read a lot that covid-19 would turn into a milder flu as time passes by and as the virus naturally evolves to become more infectious but less lethal. But this is not what happened. I was confident until Delta happened and newspaper headlines started mentioning a fourth wave (most articles I read about Spanish flu only mentioned a third wave). Today, as far as I am concerned, all bets are off. I am vaccinated with what I consider the best option available at the time (mRNA, maybe protein based vaccine would have changed my mind) and the way things are now I'll keep wearing a mask indoor, at work, in public transport for a long time and follow all the other recommendations. And I am not in the US, I live in one of the less impacted (at the moment) European country.
