IMO It is probably due to invermectin being similar to MPL that Prof. Marc and Dr Mollard initially thought that it was worth testing MPL against Covid-19. A simple Google search shows that Invermectin has been being trialed since at least early April and shown good results. It's hard to understand why it is not already being used IMO, as the saying goes " in the land of the blind the one eyed man is king" why therefore aren't the powers that be using what seems to be giving the best results so far? We seem to be waiting for the "perfect" cure before giving it the thumbs up. We can still carry on testing other molecules looking for an even better treatment but let's use what helps for now, surely? Unless there are serious side affects of course, but I haven't read about any so far. Same goes for MPL, lets compare it to Invermectin and chose the best one to help treat people. This may be exactly what is happening of course but it does seem to be taking a long time.

I wonder if Invermectin also inhibits the the mTOR pathway in some way? Is it one of the 'first' generation of mTor drugs which I've heard RA refer to? In which case we should be onto a winner.
