I still remember a post on reddit by someone claiming he'd been told by medical professionals that aKsHuALLy Cuban doctors were awful and far behind on medical advances, that they basically didn't know how to do their jobs, and despite being flown worldwide to help people were actually useless.
Cuba's success just doesn't match everything these people have ever been told.
I see people post this a lot on reddit. Obviously I have no real basis to evaluate how effective cuban doctors are but I just assume, like most times, that redditors are full of shit
