Wondering if the successful treatment Vladimir Zelenko has been using could be extended to other Jewish communities
Right now, it is simply an unreliable anecdote. You don't treat communities based on anecdote. Come back when the guy has a blinded, patient matched, controlled study of sufficient size with proper records.
eye checks may be necessary.. which is one reason the Australian HCQ trial is rather expensive.
Reports I read relegate eye damage (retinal damage) to long term use, mostly >5 years. So, if that is for sure, then it would be an issue only for prophylaxis extending years and not for acute treatment lasting two weeks at most. I forget which type of study the Australian one was.
