Know this, we will never, never reach 98% vaccination rate.
The highest vaccination rate is polio - at 92%. That is a well known, trusted vaccine.
Even with very high vaccination rates, corona viruses mutate and change. The vaccine you got this year will be worthless next year - witness the "delta variant." There will be continuing variants. Forever.
Ergo, if we're waiting for covid to go away, or we're waiting for a certain level of vaccination, or we're counting on a "one and one" vaccine - it ain't gonna happen.
We had better come to terms with simply getting on with our lives, and not living in fear.
Of course, the whole living in fear thing works for some people. It has allowed them to claim "temporary" powers over freedom and liberty that would be unthinkable under any other circumstances.
It’s like the flu, and all other viruses, they reservoir in animals, which is why they come back when the conditions are right for them to do so.
