Why Is the FDA Attacking Ivermectin, a Safe, Effective Drug?

Are the Pasteur Institute scientists also crackpots ? Their recent study does show Ivermectin reduces symptoms, such as loss of smell, in Covid infected guinea-pigs : https://doi.org/10.15252/emmm.202114122

Then there is the basic in-vitro science showing Ivermectin killing SARS-CoV2 in human cell cultures : https://doi.org/10.1016/j.antiviral.2020.104787

All well and good.. but does it work in humans ?

Harder question to answer, but combined there seems to be mounting evidence : see lists at http://ivmmeta.com
