"Everyone" is not necessary. That the only successful such studies are in areas with high incidences of Ivermectin-treatable parasitosis is a notable coincidence, isn't it?
Ivermectin failed in large studies with populations that didn't have worms.

https://ivmmeta.com provides an updated-weekly meta analysis following new publications and retractions showing significantly positive prophylactic efficacy over control in 83% of papers.
I think it is notable that you can go down the list of all the drugs on the right where they apply similar meta analysis to the treatments and they find that many drugs seem to be effective against covid. Even aspirin seems to treat covid effectively.
The irrationality in this regard seems to match the irrationality of the concerns over masks in the pro Trump camp.
(I'm in the middle. Triple vaccinated, never took Ivermectin but find it really ugly that every single discussion about it ends in a flag, downvote and shouting competition that makes it impossible to find out what the facts are. The best I've found so far is Scott Alexanders findings but I guess there could be a lot more to learn if people weren't so busily either shouting or flaggind down the stories.)
It has not really been studied as a prophylactic as in this study.
the same is true for my wife. 2 small anecdata points.
if you'd like more information about our doggie treats, so as to start a prophylactic course of treatment, please let me know.
