I mean, their vaccine is just saltwater and spit just like the Russian one. And they didn't let anyone catch it at all (or at least they tried) wich means there isn't a natural resistance either.
So in the end they completely fucked their economy (and the economy of other countries with it... But thats a different story) and just postponed the unavoidable outbreak of covid making it essentially worse than any other country. Oh and thanks to the new outbreaks covid has definitely mutated a lot...
