There are going to be all kinds of theories out there and more as time goes on and they find out more. Horror stories seem to crop up and die down as most likely not too much fact behind them, but then again, not a lot of time spend studying effects yet when everyone is focused on a cure first (please). I get the flu shot every year for similar precautionary reasons of the flu leading to further complications, so this corona is not that much different in that aspect. My personal belief is that if/when we all get a real test, we will find that most of us have had it at some point already. Keep healthy and do your best and we will be past this thing by spring (crossing my fingers). Or we will be ready for the herd immunity theory !
