That there is no definitive test to see whether or not you've had Covid-19 is a major failure in this system.
There was a lot of talk about it early on, then nothing.
Why in the world would I take an experimental gene therapy to protect against something that is no threat to me?
If covid had a kill rate like Ebola; 25-40%, I’d go with the odds and take an experimental vaccine to prevent getting it. This covid virus is nowhere near as dangerous. In fact it’s dangerous overwhelmingly just to very old folks and those with serious health issues. But so is just about everything else to those folks. My grandmother died of pneumonia after catching a cold - she was 98.
