I hope you are correct here. I just fear we end up with this thing acting like the flu. As far as I know having the flu once doesn't necessarily make it any less severe on a subsequent infection. Maybe if you get it the second time within a few months but what if that second infection is a year or 3 down the road.
Of course we just have to wait and see and hope for the best.
Hopefully this thing acts like measles and once you have it you are immune for life.
