Sinovac
"Despite having vaccinated more people than almost any other country (it has given over 60% of its population at least one shot, higher than the U.S.), Uruguay is dealing with one of the highest Covid-19 death rates in the world."
With no data available, the effectiveness of Sinovac against new Covid-19 variants is unknown. What is known of other vaccines against the Delta variant is a marked drop in protection with only one dose and a more limited drop once fully immunized. Even a small drop in efficacy would take Sinovac’s shot below the WHO threshold.
George Gao, the head of the Chinese Center for Disease Control and Prevention, acknowledged the poor efficacy of China’s vaccines at a conference in April, in what seemed to be an unintentional dissent from the party line. Gao said the country was exploring ways to “solve the problem that the efficacy of the existing vaccines is not high.”
Oooops.
