Here we have another article trying to pre-emptively dismiss a cheap and possibly effective treatment.  Sorry, a clinical trial showing significant success has already been done.  Refer to the link provided by the earlier commenter.

The paragraph beginning "in contrast" simply dismisses successful in vivo results and refers back to the pointless in vitro experiment meant to challenge an earlier in vitro experiment.  The researchers obviously were blindsided by an actual successful in vivo trial, yet try to re-assert some relevance to their meaningless in vitro work and simulated concentrations.

The article is useless and outdated, biased and dismissive against ivermectin.
