I'll make a medium-term prediction on the C19 situation, but I'll preface it by saying that part of this could get blown out depending on who wins on November 4.
When the vaccine is rolled out, it won't be mandatory in the U.S. at first. During roll out, shedding will occur from the vaccine and positive case counts will see a big spike. You can do your own research on vaccine shedding, but in a nutshell it's when a recently-vaccinated person becomes contagious with the illness itself as your body attempts to build immunity to the pathogen.
Unvaccinated people will be blamed for this spike, even though the spike itself will have occurred due to shedding of the first big wave of vaccinated people.
The right lobbyists will say the right things to our elected stooges, and a vaccine will eventually be mandated.
I'm not saying this is good or bad - it's just a prediction and I'm writing this post for discussion and to kill time. :cheers
