Uruguay has administered a two-dose regimen of Sinovac to its population, but its booster program consists of Pfizer shots.
Basically no one at all was fully-vaccinated even with Sinovac in the spring of 2021 when it got creamed by COVID-19.
Still, deaths per million of population in Uruguay at 1,892 today is a far better record without vaccination than advanced nations like France (1,984), the UK (2,387), and the US (2,842) with vaccination.
What's up with that?
