Best idea is to get everyone vaccinated, certain protection, then have boosters.
And if the folks continue to refuse to get vaccinated and their governors refuse to encourage vaccinations, then what do you propose, swami?
Get as many as possible vaccinated.
Then provide boosters when available.
Then encourage the business world, with financial incentives if possible...or by "force," to support a Vaccination Passport issued by the Federal Govt.
"No Vaccination Passport, no fly."
No fly, and No Do a lot of other things.
"No Vacc pp, no work for our company, business."
"No Vacc PP, no can enter our shop."
