We're seeing journals go to war against ivermectin by retracting favourable papers. This happened in reverse for another drug: Gardasil. Japan funded research on the safety of Gardasil and stopped using that HPV vaccine over fears regarding its safety.

Here's a paper where scientists were trying to figure out if Gardasil could lead to neuro-immunopathetic syndrome (HANS). https://www.nature.com/articles/srep36943

The journal concocted a BS reason to retract and went ahead with it. The comments section hash out the arguments for/against retraction. The argument for retraction is that the study has limitations that won't generalize to the actual condition in humans. I don't buy it- the data is helpful and the paper could explain the limitations of its data.
