Thanks Charlie, never knew of it. Reading about it, seems we are a little late for it to help much now. I look at it as I'm building my natural immunity to it..
My wife and I flew from MPLS to Phoenix and drove down to Tucson for 2 weeks in Feb of 2020 and then flew home...uh huh...only a few weeks before all hell broke loose. We were very sick shortly after we returned and later realized we had contracted the original virus and it was nasty. I've only had mild symptoms from subsequent variances since and this was only uncomfortable for 3 days. Pretty much back to normal already.
