Saying that something might be "finally something" that ivermectin can help with would have been embarrassing.
It would have been especially embarrassing because the link you gave gives two things ivermectin helps with. After concluding that ivermectin did not affect the guinea worms it says:
> No adverse reaction to treatment was seen. It appears that ivermectin can be used safely as mass chemotherapy against onchocerciasis and lymphatic filariasis in areas where guinea-worm is also endemic.
They are saying that if a patient has onchocerciasis or lymphatic filariasis it is safe to use go ahead and use ivermectin (which is the normal treatment for those) to treat those, even if the patient has guinea worms.
So good thing you didn't say it!
