So our family has officially had both versions. We got the original back in Dec2019/Jan 2020. Delta has worked its way thru the house over the past 2 weeks. I'm the last one to get it. We all can tell you from personal experience round 2 is way less bad than the first one. The first one we really couldn't control the running nose or the cough. The first one lasted 4-6 weeks across each individual. This time it is being controlled with OTC medicine without much issue. On average it's several days of runny nose, cough, and being tired. We nearly daily take Vitamin D, C, Zinc, and Elderberry.

Edit: - No we will not get the shot as natural immunity trumps shots.
