"Varients do have changed binding sites that makes original vaccines less effective."

This is fake news. You absolutely have to STOP doing this.

Sorry, Steve, but if you've been listening to people talk about how the vaccine evolves, that is exactly what is happening. The way these things bind, the part of the virus shell that does this part, has changed, making them "stickier" and harder to eradicate with a vaccine or various treatments so far attempted. And it means several of the vaccines (Johnson & Johnson, in particular) are less effective.
