Trump keeps pumping this drug but doesn't realize the way it is happening now Is that it's included in a cocktail of drugs in attempting to combat the virus. So it is given in conjunction with things like Tamiflu, asthma medication, etc. It is not being used on its own to treat people. Secondly, it is not a cureall like its being presented. If it was, we still wouldn't have people dying of the disease and you'd bet they would giving this to all patients so they can get them off the ventilators and out of the hospital asap. This is why the efficacy hasn't been definitive in its conclusions.
There are some small trials that show its not as effective at all
A small trial finds that hydroxychloroquine is not effective for treating coronavirus
So at worst, with Trump pushing this as being a cureall without definitive scientific support, he is depriving people of lupus medication for example while its benefits are minimal in fighting the disease.
That is why he should just shut the fukk up on the matter. Leave the medical shyt to Fauci and Birx because you can trust they will parse the information correctly. Trump always misquotes, misstates, and sometimes outright lie about things. I mean he obviously learned about the Spanish Flu before the conference today and even fukked up reciting the year it occurred as 1917 instead of 1918. So that is why he should stop trusting himself to recite information accurately.
