You are aware, vaccinated people can still pass on the virus, right?
Yes. And people who are vaxed won't give a shit. Reality is they will feel they've done their sacrifice and had a dose of the marvelous medicine. The only people they can harm are onens who refuse to get it. They won't care.
Of cause there will be a few that been double dosed who will catch and die. I'd assume those where on last legs already tho. They can't save everyone unfortunately. Some will slip thru net.
