The virus was unfortunately already good at spreading without causing symptoms to begin with though. In a few years, I think we are going to find that specific genetics determined whether or not individuals had severe illness. Would be awesome to know that right now. After recovering from covid last fall, my wife and I made the decision this past week to take the first shot just because of the delta variant concerns. My girls are not taking it and I would highly encourage them not to.... I don't really care what the CDC says about safety of it in kids over 12; I don't want them to figure out in 5-10 years that it affected fertility or something else.
