Major benefits of ivermectin (IVM) treatment for COVID-19 have been known since the results of 20 such randomized controlled trials (RCTs) were reported, as compiled in January 2021. Of the eight of these RCTs that tracked mortality or morbidity in patients with serious cases, seven showed statistically significant clinical improvements. The pooled mortality reduction in these eight RCTs was 78% in the treatment vs. controls groups, and the RCT that used the highest dose of IVM reported a 92% reduction in mortality (p < 0.001).
Three RCTs for IVM prevention of COVID-19 and two animal studies of IVM at low human-equivalent doses likewise reported pronounced efficacy. Here we note the recent publication ofRCTs for IVM treatment or prevention of COVID-19 in mainstream scientific journals that confirm these previously reported findings.
The consistently observed, major benefits of ivermectin (IVM) for COVID-19 treatment have been known since a January 2021 meta-study compiled results of 20 such randomized clinical trials (RCTs). 1 Of the eight of these RCTs that tracked mortality or morbidity in patients with moderate or severe symptoms(4 double-blind,1 single-blind,and 3 non-blinded), seven showed statistically significant clinical improvements(all but Podder et al.8).
The pooled mortality reduction in these eight RCTs for the IVM treatment group vs. controls was 78% (mortality of 2.1% for IVM, 9.5% for controls). The RCT that used the highest dose of IVM, 1,600 μg/kg total, had 2 vs. 24 deaths in the treatment vs.control group (n=200 each),7a 92% reduction in mortality (p < 0.001). Complementing these IVM treatment studies,three RCTs evaluated IVM for prevention in subjects exposed to COVID-19 patients. These studies reported relative COVID-19 incidences of 20%, 16% and 13% compared with incidences incontrols, withevenlower relative incidences for serious such cases. In addition, two animal studies of IVM treatment at low human-equivalent doses forSARS-CoV-2 in hamsters and for a closely related beta coronavirus in mice likewise found major, highly statistically significant treatment benefits.
Yet some skeptical reviewers had dismissed this overwhelming RCT evidence for clinical efficacy of IVM against COVID-19, claiming insufficient quality of the studies, as had been indicated by the lack of publication of any in mainstream scientific journals.
The recent publication of five such RCTs for IVM in top-tier journals, including Lancet eClinical Medicine and BMC infectious diseases, all reporting major, statistically significant clinical benefits against COVID-19, dismantles these skeptical critiques.
Among these five recently published RCTs was a prevention study of April 2021 by Seet et al. IVM was administered to 617 subjects, with 2,420 other subjects assigned to either a control group or to one of three other preventative regimens. The subjects were then tracked for onset of COVID-19 symptoms and positive nasopharyngeal PCR tests over a 42-day period. IVM at a dose of 12 mg was given just once on day one, while the three other preventative regimens were each administered daily during this 42-day period. Yet IVM at this single low dose yielded the best clinical results, reducing incidence of symptomatic COVID-19 by 50% (p=0.003) and of ARDS symptoms by 49% (p=0.012) with respect to controls.
IVM at that single low dose, however, yielded only a non-significant 8% reduction in relative incidence of positive PCR tests.
Of the four recently published RCTs that studied IVM treatment of COVID-19, Chaccour et al., as previously released in preprint, monitored outcomes for40 generally young patients with mild COVID-19 symptoms.
A single dose of IVM at 400 μg/kg significantly reduced the duration of hyposmia/anosmia(p<0.001), but gave only a modest reduction in viral load. Shahbaznejad et al. reported that IVM in a single dose of 200 μg/kg reduced duration of COVID-19 symptoms and hospitalization (p=0.02 for each).
IVM also reduced duration of coughing (p=0.02) and of shortness of breath (p<0.05). No conclusions could be drawn regarding mortality, since only one patient died, within 24 hours of hospitalization in critical condition, a 78-year old woman in the treatment group with a history of diabetes and heart failure. Mahmud et al. administered a single dose of IVM at 12 mg plus doxycycline at 100 mg twice daily for five days.18The IVM treatment group had statistically significant clinical benefits v. controls by four different measures, p=0.001 to 0.003, and had a reduced percentage of positive PCR tests at 14 days with p=0.002.Okumus et al. administered IVM at 200 μg/kg for five consecutive days, in addition to the standard of care used for both the treatment and control groups, which included azithromycin. At the end of the five-day study follow-up period, spO2 was increased; CRP, ferritin and D-dimer blood levels were reduced; and percentage of PCR-negative tests were increased vs. controls, all to statistical significance(p=0.032, 0.02, 0.005, 0.03, and 0.01, respectively).
The findings of two of these five recently published RCTs, Chaccour et al.14and Seet et al.,16both fit a pattern established in a prior RCT3and two animal studies10,11of more pronounced alleviation by IVM as a single agent of COVID-19-related symptoms and morbidities than reductions in viral load. Indeed, one RCT of IVM at an unusually high dose, 3,000 μg/kg total over 5 consecutive days, yielded a statistically significant reduction in viral load in COVID-19 patients vs. controls only for the subgroup of treated patients (45%) in which the highest levels of plasma IVM levels were obtained.19This disparity between reduction in morbidity vs. infectivity by IVM for COVID-19 may be explainable by the indicated clinically operative biological mechanism of IVM as reported in seven molecular modeling studies.
Those studies found that IVM bound strongly to regions of SARS-CoV-2 viral spike protein, one subdomain of which (RBD) controls viral binding and replication via hostcellACE2 receptors, with another subdomain (NTD) governing viral attachmentsto sialic acid (SA) binding sites on blood, endothelial and other host cells.27The latter such attachmentsof SARS-CoV-2 toSA binding sites on red blood cells (RBCs) are responsible for the clumping that is observed in vitro when virus is mixed with RBCs in this hemagglutinating virus. Whereas the common cold human beta coronavirus strains contain an enzyme, hemagglutinin esterase (HE), that releases viral-RBC clumps, the three virulent beta coronavirus strains—SARS-CoV-2, SARS-CoV, and MERS—lack HE.27IVM, if it is found to bind to NTD sites onSARS-CoV-2 spike protein, might thus limit viral virulence by blocking such hemagglutinating bindings. The biological mechanism of IVM that is operative clinically against COVID-19 remains to be confirmed, as do indications of its greater reduction of morbidity than of infectivity per the studies noted.
The recent publication of the five RCTs noted in top tier scientific journals, however, positively confirms the major, statistically significant clinical benefits of IVM, as previously reported in several prior such RCTs, for COVID-19 treatment and prevention.

Oh noes! The anti-Ivermectins here on FR ain’t gonna like this. Perhaps they enjoyed the “Just stay at home quarantining unless symptoms appear” (with NO treatment) orders. By which time it may be too late.
RE: Perhaps they enjoyed the “Just stay at home quarantining unless symptoms appear” (with NO treatment) orders.
I observe that Most of those who express skepticism of Ivermectin are the pro-vaccine folks.
I personally am not anti-vaxx. I have always advocated a BOTH/AND approach.
Since the vaccines are not yet widely available in most of the world, Ivermectin is the best fighting chance for those in poorer countries ( and it has been proven in many places like Mexico, Peru and India ).
You don’t have to be anti-IVM to be pro-vaccine.
Both are tools you can use to fight the common enemy - Covid-19
Excellent.

Fauci has blood on his hands in more ways than this!!! That little TROLL is pure evil SCUM!!
I had to have surgery. Took half dose for first dose of ivermectin but didnt take second dose when i found out it can cause lymph node issues and i didnt want my lymph nodes mistaken.
They didnt require a covid test before surgery. I was in overnight. I was in a private room so no roommate issues or visitors issue as they are now allowing visitors.
I used a product in my nose for mrsa which probably doesnt kill covid. I gargled with chlorahexadine. I showered with hibicleans.
I didnt catch covid from hospital or the two lyft drivers but perhaps because everyone is vaxxed..which i am not
The closeting of ivermectin from the public is the greatest scandal to have arisen from the whole plandemic.
Big Tech and Big Media have blood on their filthy hands.
‘bout time.
Ponder going to a Doctor and being told you are being given Ivermectrin to treat your Covid infection. Feeling hope you go home knowing you are being treated and do not seek further treatment.
Then you slowly die as your hope fades, never knowing you were given a placebo and left to die by the lying doctor so he could do a study.
People trust Doctors, why?
I do my own research, and that is why I do NOT trust Doctors. Anybody who took the jab, did no research.
This is totally irrelevant. Unless it is blessed by St. Fauci, anything other than The Vaccine isn’t worth wasting ink on. St. Fauci isn’t going to bless anything that doesn’t give political gain to Democrats.
