How many people have the Omicron variant? From what we've seen so far it doesnt have the same virulence previous incarnations have had but there is still concern for it, especially among those who are unvaccinated.

84% of hospitalized cases in South Africa are from those who haven't been vaccinated. So the same theme applies irrespective of that dope making fun of boosters and the vaccines. This variant may be less severe but part of the decreased severity it has is because of people getting 2 shots and in some cases a 3rd.
