In addition to head lice and eyelash mites, it might also be useful to point out it is the only drug to win a Nobel Prize for treatment of infectious diseases. Used by BILLIONS of people. May I remind you that you referred to this drug as a horse dewormer before you were called out.
Appeal to authority & false equivalence (apples & oranges); just because it's won a nobel prize doesn't mean it's a miracle cure against the 'rona.
I'm already dubious of the article you linked because the title uses appeal to authority (nobel prize winning) and emotional language (new global scourge).
I won't disagree that ivermectin improves life expectancy in some of those studies, but it doesn't seem to be effective in environments with less parasites.
Note also that it focuses on fatalities, not getting the disease, curing it faster than its natural course, or preventing it.
FWiW no drug has ever won a Nobel prize - researchers are awarded such prizes.
Specifically William C. Campbell and Satoshi Ōmura shared the 2015 Nobel Prize in Physiology or Medicine for their work developing a new drug, Avermectin.
From the actual press release from the actual Nobel Prize Committee [1]:
which was subsequently chemically modified to a more effective compound called Ivermectin.
Ivermectin was later tested in humans with parasitic infections and effectively killed parasite larvae (microfilaria).
Collectively, Ōmura and Campbell’s contributions led to the discovery of a new class of drugs with extraordinary efficacy against parasitic diseases.
So, in actual fact NOT used for treatment of "infectious diseases" but for treatment specifically of parasitic diseases because it was developed to be a highly effective dewormer that kills roundworm parasites.
The Nobel Prize press release that you yourself cite (although apparently have never actually read) depicts Ivermectin as a Horse Dewormer (see figure 3) - it also deworms cattle, humans, pigs, etc.
As a highly effective dewormer it is obviously positively correlated with health improvements in any large population with significant parasites - killing parasite improves overall health, more food eaten available for the host, improved immune responses, etc.
Hence the reason for many global studies showing positive results following Ivermectin treatments.
Hence also the reason quacks in the US started pushing propaganda about supposed effectiveness against COVID, setting up smoke and mirror site such as the one linked above, and spreading sly not quite untruths such as the Nobel Prize one you've repeated.
Do please read the original 2015 press release in full.
