It did. Since then they've done more studies, have started even more studies, and have deployed it en masse as a treatment. It's part of the official treatment recommendations in China, South Korea, Poland, and Italy. It's been described as a "cure" where it was used in Australia after Chinese patients demanded they be treated with it, and Australia is starting a nationwide trial. Pakistan had Bayer start up the closed production line and deliver 300,000 doses.
No but preliminary evidence is that it might speed up recovery. I'm not sure if that applies in elderly if they're already getting sever lung issues though. At that point maybe the damage is already done?
The guidance was adopted far too late but may slow the spread and reduce deaths. You have to catch things early. In Australia, Chinese immigrants came to their doctors and said "I have a symptom and I demand this prescription and here is the research and I won't take no for an answer."
Chloroquine seems to work best if you start it within the first few days of infection. So if you are say the US and have widespread BS regarding testing and prevent people from getting it, by the time they are tested and their results back it's too late. There's no chance the US will come to their senses and start using or even producing this drug in time to help stop mass deaths. Some people bought animal grade chloroquine and are self treating, but all that supply is gone now for purchase. Doctors won't prescribe it in the US either, for their own reasons.
In China and South Korea you can get tested if you have symptoms and you can start treatment if you have symptoms. So we are seeing things turn around in both places because of this and other actions.
