My perspective is a little different. I survived cancer. Part of my battle involved a stem cell transplant procedure in which my immune system was completely destroyed, my own stem cells that had been previously harvested were infused back into me to regenerate my immune system. I had to get all of my childhood shots again (I was born in 1960). The oncologist told me that I would need to get the flu shot annually from now on as well as any vaccines developed just in case...
I said all that to simply say, I didn't battle cancer for 2 yrs, and beat it just to be taken out by Covid or something there might be a vaccine or treatment for... BUT, that's me, I am not advocating people do what I do, or see my perspective...
