The Current State of Knowledge Regarding Ivermectin’s Effectiveness Against Covid-19
Eric Zuesse, February 22, 2022
There has been more scientific research done on
ivermectin to treat and cure the covid-19 disease than on any other chemical that has
been proposed for this purpose (except for hydroxychloroquine, which is by now known to be both less safe and less effective for this purpose,
though still better than nothing), and the reason for this is twofold: ivermectin is remarkably safe (which
is acknowledged even by sincere scientists who
demand a higher degree of effectiveness before any drug should be approved), and the more that it has been studied as a possible
treatment for this disease, the higher the likelihood has become established to
be that ivermectin assists in reducing or even (in some cases) curing the
disease. What is indisputable is that America’s FDA grants approval to drugs
against covid-19 disease which have far less evidence of safety and
effectiveness against the covid-19 disease, but it refuses approval to
ivermectin, which has plenty of evidence that it is safe, and even that it is
effective against this disease, though less effective than a drug needs to be
against what can be a deadly disease. Only corruption would explain this
obvious anomaly, that the FDA still refuses this authorization for ivermectin.
Clearly, for the benefit of the public, ivermectin ought to
be fully authorized as a treatment for this disease. It is not a
cure, but it can safely help to cure this disease. Its use for
this purpose would reduce the death-rate. But the FDA’s top priority
is definitely NOT to reduce diseases and deaths.
Ivermectin is a medication that, as Wikipedia says, has been approved since 1987 (35 years ago) to:
treat infestations including head lice, scabies,
river blindness (onchocerciasis), strongyloidiasis, trichuriasis, ascariasis
and lymphatic filariasis.[10][11][8][12] It works through many mechanisms to
kill the targeted parasites,[10] and can be taken orally, or applied to the
skin for external infestations.[10][13] It belongs to the avermectin family of
medications.[10]
William Campbell and Satoshi Ōmura won the 2015
Nobel Prize in Physiology or Medicine for its discovery and applications.[14]
It is on the World Health Organization's List of Essential Medicines,[15] and
is approved by the U.S. Food and Drug Administration as an antiparasitic
agent.[16] In 2018, it was the 420th most commonly prescribed medication in the
United States, with more than 100,000 prescriptions.[17] It is available as a
generic medicine.[18][19]
That last statement, “It is available as a generic
medicine,” means that the drug’s patent has expired, and so no monopoly-profits
are any longer possible for it, and so drug companies no longer promote its
use. They would therefore (for example) not donate funds to the political
campaigns of politicians who endorse legalizing the availability of ivermectin
to treat patients for the covid-19 disease. In this sense, that drug’s
inexpensiveness becomes automatically a factor against the
drug’s being approved to treat covid-19. A government driven more by
profitability (benefits to investors) than by usefulness (benefits to the
public) is not likely to approve new uses for such a drug — not even if that
drug is actually safer and more effective than some patented new drug might be,
which can be priced hundreds of times higher.
Here’s an example of how this works: on 28 June
2021, the journal Clinical Infectious Diseases published a
study “Ivermectin
for the Treatment of Coronavirus Disease 2019: A Systematic Review and
Meta-analysis of Randomized Controlled Trials”, which reported that, “Compared with the standard
of care or placebo, IVM [ivermectin] did not reduce all-cause mortality [deaths
from all causes, including covid-19], LOS [length of hospital
stay], or viral clearance in RCTs [randomized controlled trials] in patients
with mostly mild COVID-19. IVM did not have an effect on AEs [adverse events]
or SAEs [severe adverse events] and is not a viable option to treat patients
with COVID-19.” It had analyzed 10 studies, which had included a grand total of
1,173 individual patients, almost 100% of whom had had “mild” cases of the covid-19
disease; and the dose-amounts in these treatments varied widely, such as
“Single dose 400 micrograms per kilogram of body-weight,” and “Single dose 12
milligrams [12,000 micrograms] per kilogram of body-weight,” and to “300
micrograms per kilogram of body-weight, once daily, for 5 days.”
That article stated, regarding its 6 authors:
“Potential conflicts of interest. All authors: No reported conflicts. All
authors have submitted the ICMJE Form for
Disclosure of Potential Conflicts of Interest. Conflicts that the editors consider relevant to
the content of the manuscript have been disclosed.” The editors didn’t disclose
to the readers what those “conflicts” had been.
However, an entire website, https://c19ivermectin.com, is devoted to meta-analyzing every peer-reviewed
published scientific study that’s published regarding ivermectin's
effectiveness or ineffectiveness against covid-19 disease. That website says
about the 28 June 2021 article: “Details: This is a severely flawed meta analysis. An open
letter signed by 40 physicians detailing errors and flaws, and requesting
retraction, can be found at trialsitenews.com. See also bird-group.org.” That note links also to several other critiques
of the 28 June 2021 article, that requested the article’s retraction, such
as this critique
at pubpeer.com, pointing to obvious
factual errors in it, including even wrong number-counts. However, that 28 June
2021 article wasn’t retracted; it remains in the ‘scientific’ literature, which
propagandists against using ivermectin to treat the covid-19 disease can still
cite.
As-of 17 September 2021, https://c19ivermectin.com had headlined, to summarize its then-complete
survey-and-analysis on this topic, “IVERMECTIN FOR COVID-19: 63 TRIALS,
623 SCIENTISTS, 26,398 PATIENTS, 31 RANDOMIZED CONTROLLED TRIALS”, and it summarized its summary by saying: “60%
IMPROVEMENT IN 31 RANDOMIZED CONTROLLED TRIALS” from the “Database of all
ivermectin COVID-19 studies. 116 studies, 76 peer reviewed, 63 with results
comparing treatment and control groups.” It linked to each one of those 116
studies (plus linked to news-commentaries about them). So, the reader can
easily click through to each one of the studies (and to news-articles
discussing them).
Based upon those 31 randomized controlled trials, I
had headlined on 24 September 2021, “How National Propaganda Radio (NPR)
Reports About Covid and Ivermectin”, and reported against that NPR ‘news’-report’s stenographic presentation
of the U.S. Government’s condemnation and prohibition against using ivermectin
to treat the covid-19 disease. (Subsequently, reader-comments to my article
were deleted by
Discuss, which has a virtual monopoly over reader-comment sections at small
news-sites in America, but
ultimately those reader-comments were able to be restored by the site’s
editors.)
Right now, https://c19ivermectin.com is headlining “Ivermectin for COVID-19: real-time meta
analysis of 78 studies: Covid Analysis, Feb 18, 2022, Version 176”, and it reports:
Statistically significant improvements are seen for
mortality, ventilation, ICU admission, hospitalization, recovery, cases, and
viral clearance. All remain significant after exclusions. 50 studies from 46
independent teams in 21 different countries show statistically significant
improvements in isolation (38 primary outcome, 35 most serious outcome).
•Meta analysis using the most serious outcome shows
63% [53‑72%] and 83% [74‑89%] improvement for early treatment and prophylaxis,
with similar results after exclusion-based sensitivity analysis, for primary
outcomes, for peer-reviewed studies, and for RCTs [randomized controlled
trials].
•Results are very robust — in worst case exclusion
sensitivity analysis 62 of 78 studies must be excluded to avoid finding
statistically significant efficacy.
•While many treatments have some level of efficacy,
they do not replace vaccines and other measures to avoid infection. Only 24% of
ivermectin studies show zero events in the treatment arm. Multiple treatments
are typically used in combination, which may be significantly more effective.
•No treatment, vaccine, or intervention is 100%
available and effective for all variants. All practical, effective, and safe
means should be used. Denying the efficacy of treatments increases mortality,
morbidity, collateral damage, and endemic risk.
•Over 20 countries have adopted ivermectin for
COVID-19. The evidence base is much larger and has much lower conflict of
interest than typically used to approve drugs.
It reports that:
27 of the 32 Early Treatment studies have shown that
the ivermectin-receiving patients improved more than the
non-ivermectin-receiving patients did.
25 of the 30 Late Treatment studies showed that the
ivermectin-receiving patients improved more than the non-ivermectin-receiving
patients did.
16 of the 16 Prophylaxis (prevention of spreading
the disease, such as protecting healthcare workers against catching the disease
from their patients) studies showed that the disease spread less from the
patients who were taking ivermectin than from the patients who weren’t. In 100%
of studies, ivermectin-takers had spread the disease less than control-group
patients did.
In 68 of the 78 studies, the results were better for
(and from) the patients who were taking ivermectin than for (and from) the
patients who weren’t.
The total number of patients studied, as-of 18
February 2022, were 85,767 (as opposed to the earlier 26,398), and the added
60,369 patients were producing a 64% success-rate with ivermectin (as compared
to the prior 60%). So: as would be expected to be the case for an effective
medication, increased experience with the drug were increasing the success-rate
of its application.
However, there is a stark contrast between that
meta-analysis and another one, which was done by a professional organization
whose report is vaguer and less clear in virtually every way:
The Infectious Disease Society of America (IDSA) has
published “IDSA Guidelines on the Treatment and Management of Patients with
COVID-19” Updated on 16 February 2022, and its section that’s devoted to “Recommendations 24-25: Ivermectin” states:
Recommendation 24: In hospitalized patients with
COVID-19, the IDSA panel suggests against ivermectin outside of the context of
a clinical trial. (Conditional recommendation, very low certainty of evidence)
Recommendation 25: In ambulatory persons with
COVID-19, the IDSA panel suggests against ivermectin outside of the context of
a clinical trial. (Conditional recommendation, very low certainty of evidence)
That meta-analysis — unlike the one
at https://c19ivermectin.com, fails to link to the studies that it
discusses, and is altogether inferior in its presentation (far more
difficult to verify or disconfirm), as well as being less comprehensive and
less persuasive in virtually every other respect. Moreover, its claim of “very
low certainty of evidence” on the matter, is not documented, at all, against
the very specific precise numerical odds that are calculated, and presented,
at https://c19ivermectin.com, which show the exact opposite: stunningly high-probabilities,
statistically very clear findings. Furthermore, even the IDSA
report isn’t arguing that ivermectin’s dangers to covid-19 patients outweigh
its benefits to those patients, and so the extreme safety of this drug
(ivermectin) is going essentially unchallenged, even by presenters who are
trying to persuade their readers that there’s a “very low certainty of
evidence” regarding ivermectin’s impact upon covid-19 disease.
Given the extremely low cost of such an amazingly
promising and demonstrably successful medication against the covid-19 disease,
can there be any reasonable doubt that governments ought to be
encouraging, instead of blocking, its use (at least until something better is
discovered and proven to treat against the covid-19 disease)?
However, because Merck’s Molnupiravir proposed anti-covid-19 drug, and
Pfizer’s Paxlovid proposed anti-covid-19 drug, stand ready to
make many billions of dollars for investors, and ivermectin can’t do that, the
U.S. Government and other governments that represent their billionaires instead
of their public, are blocking approval of ivermectin for
treating covid-19, even if ivermectin is far safer, and might be even more
effective against covid-19, than either of those new drugs would be. That’s why
America’s FDA warns “Why You Should Not Use Ivermectin
to Treat or Prevent COVID-19”, and says “There’s a lot of misinformation around” ivermectin, as a
treatment-option on covid-19 (yes, and some of this “misinformation” is coming
from themselves).
According to GoodRx's “Paxlovid vs. Molnupiravir for COVID-19”, “Studies suggest that Paxlovid can lower the risk
of severe COVID-19 for high-risk people by almost 90%. Studies suggest Molnupiravir can lower this risk by about 30% [see p. 16 there].” If those expectations become borne out, then
Paxlovid will probably be lots more effective against covid-19 than even
ivermectin is. However, if Paxlovid will be priced so high as to be
unaffordable in most countries, then the delays in approving ivermectin will
probably ultimately end in many countries; and, at that point, all of the
millions of people who could have been saved by ivermectin
from dying from covid-19 would then have been viciously simply wasted, killed,
by the governments that are (as is so obvious in this case) placing investors’
interests above the public’s interests. And maybe some people
will notice this, even if the ‘news’-media likely won’t.
Other promising (but less-studied) non-patentable anti-covid-19
treatments include melatonin, and quercetin.
Whereas a society which is being driven more by
profitability than by usefulness is not likely to approve new uses for such a
drug as ivermectin (or for non-drug nutrients), the present moment could turn
out to be a terrific time to buy Pfizer drug stock. Only people who are looking
in their rear-view mirrors will know for sure whether this will turn out to
have been the case. But that’s not the major concern of the general public,
even if they might happen to vote (in political elections)
as-if it were (because those had been the candidates whom the
sickness-industries and ‘news’-media had been propagandizing for).
In a ‘democracy’, the candidates of investors win
almost all the time — especially investors in sickness, war, ‘news’-media, and
extraction-industries such as mining and fossil-fuels. It’s the new type of
aristocracy, which rose up and, in America, has (after the 1945 end of WW II)
come to replace what had been Britain’s aristocracy in 1776 (America’s
aristocrats, instead of Britain’s, ruling here).
