Twitter blocked an entire medical journal’s website for publishing one study proving the efficacy of Ivermectin as a treatment for COVID-19. The antiparasitic drug has shown promise as a preventative measure for the coronavirus.

Karl Denninger, known on Twitter as Tickerguy, posted a link to a study published in the European Journal of Medical and Health Sciences that concluded that Ivermectin could be effective as pre-exposure prophylaxis (PreP) against COVID-19. Only 6.9% of the study participants tested positive for the virus after taking Ivermectin. On the other hand, 73.3% of those who did not take the drug tested positive.
