Ethernet, I am not sure where you are getting your facts.
A bit off topic, so I'll keep it brief.
Thomas Borody has never won a nobel prize. He developed triple H.Pylori therapy.
The prize was won by Barry Marshall and Robin Warren for the discovery of H.Pylori - prior to that gastic ulcers were thought to be secondary to worry and gastric hypersecretion.
I read your article (an interesting read) from the Daily telegraph, hosted on a commercial website promoting its founder (Prof Borody) who specialises in faecal transplants (there are recognised indications for this).
The initial evidence for invermectin on preprint was from registry studies from the surgisphere registry. The same one that was used in the discredited and retracted Lancet and NEJM articles on hydroxychloroquine. A couple of articles in
sciencemag and
thescientist discuss this. This paper has now been withdrawn.
Following studies, the latest being from Florida. "ICON (Ivermectin in COvid Nineteen) study: Use of Ivermectin is Associated with Lower Mortality in Hospitalized Patients with COVID19" by Cepelowicz Rajter. Again a retrospective cohort study, but it showed an association with a lower mortality. They concluded with "These findings should be further evaluated with randomized controlled trials." So the evidence is in the fledgling stage and needs further investigation, like hundreds of other drugs.
"Dr Borody says he (Pres. Trump) may absorb enough through his skin to protect him, despite people around him at the White House becoming ill." - I would suggest Prof Borody should stick to gastroenterology, as he knows very little about pharmacokinetics. Ivermectin is poorly absorbed though skin, and is very, very unlikely to get to therapeutic levels.
