That's not exactly what it says. To put it in numbers out of the 64 deaths.
32 of the dead had not been vaccinated.
19 of the dead had been originally vaccinated but never had boosters. This means they were basically unvaccinated at this point.
13 of the dead had been vaccinated and had boosters. (but it doesn't state how many boosters or how long since their last booster)
My doctor told me,about 2 weeks ago, that the vaccines available now are bivalent.
