People who have been vaccinated three times.
In particular, triple vaxxers those who enthusiastically went to get a third COVID shot in the year 2021.
The exact phrase seems to have been first used on Twitter in June 2021.
“The new goal posts”, Dr. Tam continued “are that we require 104% of the population, both eligible and ineligible, to be triple vaccinated”

So is one jab "vaccinated" and two jabs "double vaccinated"? When we have to get the 3rd jab will we then be "triple vaccinated"? 4th jab "Quadruple vaccinated"? Do they keep counting forever, like its some kind of huge achievement the more you get?
