Well the unscientific NGOs have it confused. COVID does not necessarily cause SARS, look up SJS/CoV-2 or SIADH-CoV-2 same virus or different... clearly the same but different associated syndromes.
I mean we have no idea their long term effects, it might be a good idea that not 100% of people take it just incase we end up like the 'Children of the men' plotline.
He didn't waste his money on treatments from certain near term death.
His tumors had been growing for decades and there was little left to save him. Some doctors wanted to scam him others told him the reasonable way to go.
These are very long train lines, it would be turning a one man job into one that takes tens of thousands.
It would be interesting if they had short areas where the train recharged the battery on the move... which may exist naturally with engine breaks.
They actually have the same mechanism of action for being effective against COVID. They both are able to inhibit protease... they found out the mechanism for ivermectin being effective and so used the better medication to do that more effectively. Or they always knew this worked and were undersupply.
This is a false dichotomy, just because a drug is used as an anti parasitic does not mean it has no reason to not work for other ailments.
Ivermectin binding pushes glutamate-gated chloride channels channels open, increasing the flow of chloride ions and hyper-polarizing the cell membranes. The fact that this action kills parasites does not cause it to not affect a virus's ability to replicate.
Ivermectin is not THAT safe. I mean its safety record is at approximately 1/20000 chance of killing you or putting you in some sort of coma...
It also is very toxic to certain genetic mutations within the human population.
It also is underwhelming in its effectiveness.
