That number strikes me as a wild exaggeration. But I suppose if they count the Chinese vaccines...
I certainly wouldn’t count the Chinese vaccines for anything. They’re garbage. In the absolute best case scenario, they’re no better than 50% effective. The real number (particularly with the Delta variant) is likely much lower.
Every country that went with China’s vaccines has regretted it, and that includes China. China is now working on deploying the Pfizer mRNA vaccine to their own people, having witnessed first-hand what an absolute failure their vaccines are.
