However, this cycle could continue indefinitely until brought under control by a competent vaccine.
So, as I see it, fingers need to be crossed that no mutation occurs that defeats the vaccine.
OB, what's your take on my assessment?

I was thinking specifically about SARS and MERS. Neither of those have returned since circulating around the UK a few years ago.
In terms of your example, I guess that if later variants of a virus are more deadly and/or more contagious, such variants will take away the hosts on which the original viruses rely.
