Ivermectin has also been found to work against HIV, influenza and Zika virus

That makes little to no sense. Ivermectin is a potent drug for dealing with parasitic infections, not viruses.

Ivermectin has long been clinically administered for the treatment of parasitosis (63), but has recently come to attention as a potential inhibitor of IMPα/β (64). Ivermectin inhibition of IMPα/β has shown to inhibit the replication of RNA viruses such as dengue virus and HIV-1 (64). Ivermectin was recently tested for the inhibition of IAV in vitro, with nuclear import of vRNP complex (of both wild-type and antiviral MxA escape mutant) efficiently inhibited (65). Given ivermectin’s longstanding record of clinical applications and FDA-approved status, repurposing of this drug for the treatment of IAV should be considered, especially while under threat of pandemic IAV outbreak.

The bolded part is what makes it useless. A lot of things can kill/inhibit in vitro (in a glass petri dish). It's in vivo (i.e. in life, in the body) that matters.
