Worth researching, yeah maybe. Covid was new, there was no medicine against it, so you'd expect any worthwhile scientist to throw whatever they got at the wall to see what would stick.

But it's a whole different story between scientists testing something in a study and a non-medically-trained politician recommending the non-medically-trained public to off-label self-medicate with a drug that hasn't been tested, with no dosage recommendations and with no medical oversight.

As someone who works in healthcare and regularly reads scientific studies you should know the difference.
