I think your scenario could very well play out all over the world.
This fall will be interesting.
You do realize the first groups to be vaccinated were in March 2020 there is well over a million people who have had the MRNA vaccine for over a year and there has not been a mass die off. Anti vaxxers are as bad as flat earthers. The military will be mandating the mrna vaccines in September which means they know that full FDA approval is going to happen before September for one or all of the MRNA versions in use. The Israelis have well over four million data points that prove with absolute scientific certainty the mrna vaccines are 90+% effective against the Alpha, beta strains for all forms of infection asymptomatic or symptomatic. The Delta strain has a 66% symptomatic effective rate and a 93% serious/ hospitalization prevention rate. There are at least a dozen power reviews to that data ALL of them got the same results this science has been satisfied. Those are facts not opinions verifiable, quantitatively proven facts not opinions spewed forth in a internet anonymous chat like so many do here. I encourage anyone to post valid peer reviewed science that shows the ineffectiveness of either of the MRNA versions in use the simple fact is you can’t they are proven without a shadow of a doubt toI work. But go ahead post opinions it’s a free country won’t make them any more true than the earth is flat.
