They passed out ivermectin like candy In Brazil and South America and didn't see much of an effect. It kills the virus in vitro but need much higher levels in the bloodstream to kill it reliably in vivo.

Abstract In March 2020, an expert panel called the Front Line COVID-19 Critical Care Alliance (FLCCC) was created and led by Professor Paul E. Marik, with the goal of continuously reviewing the rapidly emerging basic science, translational, and clinical data in order to gain insight into and to develop a treatment protocol for COVID-19. At the same time, many centers and groups employed a multitude of novel therapeutic agents empirically, and within clinical trials, often during inappropriate time points during this now well-described multi-phase disease. Either as a result of these frequent trial design failures, or due to the lack of their insufficient anti-viral or anti-inflammatory properties, nearly all trialed agents have proven ineffective in treating COVID-19 as of November 11, 2020. Based on a recent series of negative published therapeutic study results, in particular the SOLIDARITY trial, they now virtually eliminate any treatment role for remdesivir, hydroxychloroquine, lopinavir/ritonavir, interferon, convalescent plasma, tocilizumab, and monoclonal antibody therapy. Despite this growing list of failed therapeutics in COVID-19, the FLCCC recently discovered that ivermectin, an anti-parasitic medicine, has highly potent real-world, anti-viral, and anti-inflammatory properties against SARS-CoV-2 and COVID-19. This conclusion is based on the increasing numbers of study results reporting effectiveness, not only within vitro and animal models, but also in numerous randomized and observational controlled clinical trials. Repeated, large magnitude improvements in clinical outcomes have now been recorded when ivermectin is used not only as a prophylactic agent but also in mild, moderate, and even severe disease states. The review that follows of the existing evidence for ivermectin relies on “emerging” data in that, although compelling, only a minority of studies have been published in peer-reviewed publications with the majority of results compiled from manuscripts uploaded to medicine pre-print servers or posted on clinicaltrials.gov
