Tick bite leads to Guillain-Barré Syndrome

tick-bite-Guillain-Barre

Welcome to another Inside Lyme Podcast with your host Dr. Daniel Cameron. In this episode, Dr. Cameron will be discussing the case of a 71-year-old woman who was initially diagnosed with Ehrlichia, a tick-borne illness but later developed Guillain-Barré Syndrome.

The study, entitled “Case of ehrlichiosis induced Guillain-Barre Syndrome in a 71-year-old female,” was published by Malhis and colleagues in the journal IDcases

The woman’s initial symptoms occurred over a 3-week period and included: generalized weakness, dizziness, visual changes, chills, a fever, neck and abdominal pain.

After presenting to the hospital, she was diagnosed with Ehrlichia, a tick-borne illness, based on a low platelet count, elevated liver function tests, an insect bite, a positive Ehrlichia test by PCR, and absence of another illness.

The woman was treated with doxycycline and her symptoms improved.

However, approximately one week later, she returned to the hospital with worsening symptoms and “numbness and areflexia in her lower extremities which progressed since her first encounter,” the authors write.

She developed an unsteady gait, which required a walker and had tingling in her feet and difficulty urinating. She required a straight foley catheterization.

“Although ehrlichiosis is not a common cause for GBS, the pathogenesis is like Lyme disease or Campylobacter jejuni,” the authors write.

“This patient had clinical symptoms that were like tick-borne illness yet as her disease progressed, it illustrated the need for an expanded differential diagnosis.”

The woman was diagnosed with an acute inflammatory demyelinating polyneuropathy, often referred to as Guillain-Barré Syndrome.

There was no evidence of another tick-borne illness including Lyme disease, Babesia, Heartland or Bourbon Virus.

The patient improved significantly with IVIG and was discharged to a rehabilitation center.

“Although ehrlichiosis is not pathognomonic for Guillain-Barre, it is important to not rule out as a cause,” the authors point out. “With the COVID-19 outbreak, there have been reported cases of GBS induced by COVID. It too can cause an immune response to the nervous system.”

Bourbon virus

“There have been reported cases of tick-borne illness that have not recovered despite tetracycline treatment,” reports Kosoy et al.2

They cite the case of a 50-year-old male from Eastern Kentucky who was found to have several tick bites, enlarged Lymph nodes, a macular papular rash, low platelets, low white count, and complaints of nausea, vomiting and diarrhea, followed by fever, myalgias, headaches and arthralgias.

The patient’s labs were negative for known tick-borne pathogens and he failed tetracycline treatment.

“Multiorgan failure developed, and he died 11 days after illness onset from cardiopulmonary arrest,” the authors write.

The man was later diagnosed with the Bourbon virus, a newly recognized tick-borne illness.3

Guillain-Barré Syndrome

 Guillain-Barré Syndrome (GBS) is an acute autoimmune demyelinating polyradiculoneuropathy that induces rapid and progressive flaccid weakness, according to Malhis.1 GBS can be life threatening if it progresses to involving the diaphragm.

 There are a number of causes of GBS. Respiratory and gastrointestinal infections can lead to GBS.  Lyme disease, tick-paralysis, HIV, and West Nile Virus can also lead to GBS.  There is also a very slim chance (1 in a million) that a flu vaccine can lead to GBS.

Treatment for GBS includes intravenous immunoglobulin (IVIG) therapy or plasma exchange. Steroids have not been helpful in treating the condition. An estimated 85% of patients recover their independent ambulation.

The authors conclude: “It is important to keep a broad differential as sometimes common syndromes do not always come from common pathogens and with the COVID-19 pandemic having similar results, we are learning new things that may potentially be new standards in medical education.”

The following questions are addressed in this Podcast episode:

  1. What is the Guillain-Barré Syndrome?
  2. What is the treatment for Guillain-Barré Syndrome?
  3. What is the Bourbon and Heartland virus?
  4. Why are there concerns for individuals with COVID-19?

**Comment**

This article states that COVID can also induce GBS, which begs the question – why would Dr. Cameron believe and encourage Lyme/MSIDS patients to get the COVID injections?  The article admits that COVID can cause an immune response to the nervous system, which Lyme/MSIDS patients are already struggling with.  Illogical.

Please read and understand the risks of the COVID injections – and there are many:

A Literature Review & Meta-Analysis of the Effects of Lockdowns on COVID-19 Mortality. CDC Finally Admits Natural Immunity Trumps “Vaccines.” It’s Time to Rehire Unvaxxed Workers

A_Literature_Review_and_Meta_Analysis_of_the_Effects_of_Lockdowns

January 2022

By Jonas Herby, Lars Jonung, and Steve H. Hanke

John Hopkins Institute for Applied Economics, Global Health, and the Study of Business Enterprise

Abstract
This systematic review and metaanalysis are designed to determine whether there is empirical evidence to support the belief that “lockdowns” reduce COVID19 mortality. Lockdowns are defined as the imposition of at least one compulsory, nonpharmaceutical intervention (NPI). NPIs are any government mandate that directly restrict peoples’ possibilities, such as policies that
limit internal movement, close schools and businesses, and ban international travel. This study employed a systematic search and screening procedure in which 18,590 studies are identified that could potentially address the belief posed. After three levels of screening, 34 studies ultimately qualified. Of those 34 eligible studies, 24 qualified for inclusion in the metaanalysis.
They were separated into three groups: lockdown stringency index studies, shelterinplaceorder (SIPO) studies, and specific NPI studies.

An analysis of each of these three groups support the conclusion that lockdowns have had little to no effect on COVID19 mortality.

More specifically, stringency index studies find that lockdowns in Europe and the United States only reduced COVID19 mortality by 0.2% on average. SIPOs were also ineffective, only reducing COVID19 mortality by 2.9% on average. Specific NPI studies also find no broadbased evidence of noticeable effects on COVID19 mortality.

While this metaanalysis concludes that lockdowns have had little to no public health effects, they have imposed enormous economic and social costs where they have been adopted.

In consequence, lockdown policies are illfounded and should be rejected as a pandemic policy instrument.

CDC Admits Natural Immunity Trumps Vaccine Immunity — 5 Months After Touting Vaccines as Superior

Five months after issuing a statement that vaccine immunity protects against COVID better than natural immunity, the Centers for Disease Control and Prevention sent a report showing the opposite is true, at least when it comes to the Delta variant.

A Jan. 19 report from the Centers for Disease Control and Prevention (CDC) showed natural immunity against COVID was at least three times as effective as vaccination alone at preventing people from becoming infected with the Delta variant.  (See link for article)

Important quote regarding higher hazard rates for hospitalization in the vaxxed:

“This is potentially a concerning finding in that it suggests the vaccine could be interfering with natural immunity,” Setty said.

Natural immunity gets another boost from two new U.S. studies

CDC and Johns Hopkins studies show strength and duration of natural immunity protection

Two newly released studies show the power of natural immunity following recovery from COVID-19 sickness. The Centers for Disease Control and Prevention (CDC) says:

“previous SARS-CoV-2 infection also confers protection against severe outcomes in the event of reinfection.”

Johns Hopkins found that natural immunity developed from prior variants reduced the risk of infection with the Omicron variant.  (See link for article)

Summary:

  • natural immunity was six times stronger during the Delta wave than vaccination 
  • Dr. Makary states that “hybrid immunity” (“vaccinated” & infected) increases immunity by 3.8%, while Dr. Urso, on the other hand, states there’s no such thing as “super immunity.”  Natural immunity is robust, long-lasting, and sufficient. 
  • Makary believes we aren’t seeing new “vaccinations” because people are hardened by excessive government policies and are choosing to forgo the shots. He also states “no healthy child has ever died of COVID that we know of.”
  • The Omicron wave in Africa subsided quickly with modest hospitalizations because close to 80% had been previously infected by variants.
  • The CATO institute weighed in and stated that “universal vaccine mandates are irrational in ignoring naturally acquired immunity from infection and recovery…..If OSHA had reviewed the medical and scientific literature regarding the relative protection efficacy of natural immunity compared to “vaccination”, it is unlikely the agency would be successful in establishing a factual basis for forced “vaccination” of COVID-recovered individuals.  Given the trivial – if any – benefit to either the individual or the public from compelled “vaccination” of Covid-recovered individuals, that evidence of elevated adverse effects requires an especially high standard of proof by regulators to overcome.”
  • Dr. Makary states, “By firing staff with natural immunity, employers got rid of those least likely to infect others.” “It’s time to reinstate those employees with an apology.”
  • Makary states it’s time to rehire the fired for three reasons: it was unfair to begin with, we have therapeutics, and many have natural immunity. “The risk of somebody who has natural immunity getting hospitalized is 3 per 10,000,” which is identical to the risk of someone with hybrid immunity – so getting a booster did NOTHING to change hospitalization numbers.
  • Makary noted that public health officials are falsely reporting higher numbers of COVID deaths than reality shows, and cases have declined steeply.
  • It’s normal to have a massive influx of patients every winter from a number of respiratory pathogens, the problem this time is a massive staffing shortage.  One in five health care workers have left. 

Washington State was so short-staffed they told workers who had COVID to come back into work – even with symptoms.

  • There’s only been ONE death in 52,000 Omicron cases in the Kaiser CA study, which is LOWER than influenza.
  • The article then reported on a North Carolina man who said a hospital refused to carry out a kidney transplant because he’s unvaccinated against COVID-19. He is willing to “die free” rather than comply with their vaccine requirement. He’s had the coronavirus twice before and believes getting the vaccine should be a personal choice, not a requirement.  The hospital doesn’t care about science and is holding its ground. Sadly, this has been happening globally.  A three year old from Cyprus was also refused lifesaving surgery in three countries because his parents weren’t vaxxed.  Go here to send an email to your members of Congress to stop this violation of medical ethics.
  • Noah Carl noted in his review of the Danish study, that there’s no obvious need for people who have recovered from COVID to get vaccinated.

“The tricky part may be getting this message through to politicians.”

Illogical COVID madness continues…..

Established Populations of Rickettsia Parkeri-Infected Amblyomma Maculatum Ticks in New York City, NY, USA

https://www.liebertpub.com/doi/abs/10.1089/vbz.2021.0085?journalCode=vbz

Established Populations of Rickettsia parkeri-Infected Amblyomma maculatum Ticks in New York City, New York, USA

Published Online:https://doi.org/10.1089/vbz.2021.0085

Objectives: We sought to determine the habitat associations and pathogen status of Amblyomma maculatum (Gulf Coast tick) ticks in New York City (NYC), New York, USA, a newly expanded portion of their range.

Methods: We collected 88 ticks from two NYC parks on Staten Island, one of the five boroughs of NYC, and compared our findings with similar habitat in Brooklyn, New York during the same time period (April 30–September 1). We tested 76 for pathogens.

Results: We found adult and immature ticks in native and invasive grasses at Freshkills and Brookfield parks on Staten Island. No A. maculatum ticks were found in Brooklyn.

  • 52.6% of ticks tested were infected with Rickettsia parkeri—the etiological agent of R. parkeri rickettsiosis.

Conclusions: This high rate of R. parkeri in a dense urban center is of concern to the medical community, who should be aware of this species’ presence and the symptoms of R. parkeri rickettsiosis.

Cats and cars help scientists study Lyme disease

Study from Mount Allison University researchers uses citizen science to find a new source of Lyme disease bacteria in New Brunswick mice

SACKVILLE, NB – A new study from Mount Allison University, aided by cats and cat owners, is shedding light on a new source of Lyme disease bacteria in the Maritimes and how the Lyme disease pathogen in transmitted in wildlife.

Mount Allison University biology professor Dr. Vett Lloyd and graduate student Chris Zinck recently published a paper, Borrelia burgdorferi and Borrelia miyamotoi in Atlantic Canadian wildlife, in the peer-reviewed journal PLOS ONE.

Lloyd and Zinck partnered with local veterinarians and cat owners to collect wildlife specimens and study them for zoonotic diseases – diseases such as Lyme disease that are transmitted from wildlife to humans. In this latest study, Lloyd, who heads Mount Allison’s Tick Lab, and Zinck have found a new wildlife species, the jumping mouse, that can carry Lyme disease in New Brunswick. The pair also discovered that one of the types of Lyme disease bacteria can be transmitted through the placenta to the young in that mouse species.

“We know that Lyme disease is abundant in New Brunswick wildlife,” says Lloyd. “But we didn’t know how abundant it was in wild animals in the province and these findings raise more concerns about the potential risks of Lyme disease in our region.”

To collect wildlife specimens, researchers used a Citizen Science approach, enlisting the assistance local cats and motorists in providing a large number of mice, voles, shrews, squirrels, porcupines, and other animals, to study.

Lloyd came up with the community-based approach at her home with her cat Entropy, a calico who hunts with surgical precision.

“As I looked at yet another one of Entropy’s ‘gifts’ on the front step, I wondered if there was a way for these little lives to contribute to science,” says Lloyd. “I had the same thought on my drive into work along the TransCanada highway each day, seeing animals on the side of the road.”
Zinck, who completed both his undergraduate and master’s degrees at Mount Allison and is currently completing his PhD at the University of Saskatchewan, also hit the road in the name of science. With a safety vest and permits in tow, he collected and dissected several hundred accidentally killed wild animals, finding both the known Lyme disease bacteria, Borrelia burgdorferi, and a different kind, Borrelia miyamotoi, in specimens.

“This work is important for the health of people and their pets as Borrelia miyamotoi infection would not be detected by the standard Lyme disease tests,” says Lloyd. “Even more surprisingly, we found that an infected jumping mouse mother had passed the infection on to her fetuses. This has implications for the health of wildlife and although few people would worry too much about the health of wild mice, it does have implications for a rapid increase in infected mice and the possibility that an infected human mother could pass on the infection to her child.”

Lloyd and Zinck hope that this work will help people realize how closely people and wildlife are connected and that the community can participate in advancing science.

BMJ Demands Immediate Vaccine Data

BMJ Demands Immediate Vaccine Data

Analysis by Dr. Joseph Mercola
Feb. 1, 2022

Story at-a-glance

  • BMJ editor Peter Doshi has publicly called for release of raw data from the clinical trials that led to the emergency use authorization of the COVID-19 shots. The FDA has a statutory obligation to publish the Pfizer data after drug approval, leaving Moderna, Johnson & Johnson and AstraZeneca to provide the raw data
  • The delay in releasing raw data is reminiscent of Roche’s handling of Tamiflu and Gilead’s determination to get authorization for remdesivir to treat COVID-19, despite clinical data demonstrating the drug showed little or no positive effect
  • At least one Pfizer testing facility had poor practices, including data that were falsified, patients who were unblinded and poorly trained people hired to administer the injections
  • In an opinion piece published coincidentally on the day the FDA announced full approval of the Pfizer injection, Doshi noted Pfizer’s August 2021 preprint paper held no new information since April 2021, and the shot demonstrated waning immunity in Israel, where it was used exclusively

While other Big Pharma manufacturers have developed and released a COVID-19 genetic therapy injection, only shots from Pfizer, Moderna and Johnson & Johnson have been approved in the U.S.1

The British Medical Journal (BMJ) editor Peter Doshi, an associate professor of pharmaceutical health services research at the University of Maryland School of Pharmacy, has called for the release of the clinical trial raw data on which the emergency use authorizations were based.2

As of December 2021, there were 12 countries with the capacity to produce the shots being distributed throughout the world, with approximately 200 vaccine candidates that are in preclinical development.3 According to OpenVAERS,4 there have been 1,053,828 adverse events reported as of January 14, 2022, and of those 593,078 (56.2%) are attributed to the Pfizer/BioNTech shot.

Of the three emergency use authorization approved shots in the U.S., Pfizer’s Comirnaty was the only one approved for full use by the FDA in August 2021.5 The thing is, Comirnaty is not available in the U.S., and won’t be made available as long as doses of the Emergency Use Authorized Pfizer shot, BNT162b2, remain.6

In other words, the shot that has triggered more than half of all adverse events is the one that is being touted as approved by the FDA — when in reality the shot that was actually approved isn’t even available yet. Dr. Peter Marks, FDA’s director of the Center for Biologics Evaluation and Research wrote this as justification for the approval to do this in the FDA press release:7

“Our scientific and medical experts conducted an incredibly thorough and thoughtful evaluation of this vaccine. We evaluated scientific data and information included in hundreds of thousands of pages, conducted our own analyses of Comirnaty’s safety and effectiveness, and performed a detailed assessment of the manufacturing processes, including inspections of the manufacturing facilities.”

It is the FDA’s statutory obligation8 to publish this “incredibly thorough” evaluation of the data and their own analysis within 30 days of a drug approval. Yet, after a Freedom of Information Act request and subsequent lawsuit by a nonprofit group to release the data,9 the FDA proposed to release documentation over many decades.

Ultimately, they asked a federal judge to give them 75 years to complete the process,10 but in January 2022 a federal judge ordered the FDA to accelerate this schedule to eight months.11

Pfizer Won’t Accept Requests for Trial Data Until 2025

According to Doshi,12 it will take Pfizer at least 24 months after the study completion date listed on ClinicalTrials.gov13 to even consider a request to release the primary data. Doshi calls this an “unacceptable delay,” and yet the lack of access to data is not unique to Pfizer.

Moderna and AstraZeneca14 have both indicated they will have similar delays in releasing their data.15 Since only the data from Pfizer can be released by the FDA, it falls to Moderna, Johnson & Johnson and AstraZeneca to provide the raw data. Doshi points out that raw data for other therapeutics tied to COVID-19 are also difficult to uncover.

For example, the published reports of the monoclonal antibody therapy produced by Regeneron state that any raw data will not be released to others.16 Only the methods and findings will be released, and the raw data will only be considered once the drug has been approved and if there’s legal authority to share it.

Likewise, Doshi notes the raw data from the National Institutes of Health for the drug promoted to treat COVID-19 — remdesivir — is limited, with the accompanying explanation: “The longitudinal data set only contains a small subset of the protocol and statistical analysis plan objectives.”17 Doshi argues the point, writing:

“We are left with publications but no access to the underlying data on reasonable request. This is worrying for trial participants, researchers, clinicians, journal editors, policy makers, and the public. The journals that have published these primary studies may argue that they faced an awkward dilemma, caught between making the summary findings available quickly and upholding the best ethical values that support timely access to underlying data.

In our view, there is no dilemma; the anonymized individual participant data from clinical trials must be made available for independent scrutiny.”

Access to the underlying data is necessary for transparent decision-making. Each of these are essential steps for public health safety. Doshi notes18 that had information been revealed as to why the vaccine trials were not used to test efficacy against the infection, countries would have learned earlier about how the vaccine allowed transmission in the pandemic and would have been able to plan public health strategies accordingly.

Pfizer has been a habitual offender in shady dealings, having been sued in multiple venues over unethical drug testing, illegal marketing practices,19 bribery in multiple countries,20 environmental violations,21 labor and worker safety violations and more.22,23

Doshi cites documentation24 that three of the companies have had past criminal and civil settlements costing them billions of dollars, one pleaded guilty to fraud and other drug companies have jumped into developing a genetic injection with no track record before the pandemic. These actions create doubt that the raw data will adequately support the manufacturers claims.

Lack of Raw Data After Drug Release Reminiscent of Tamiflu

Doshi recalls that 12 years ago the scientific community called for the release of raw data from clinical trials from another drug that was stockpiled by governments around the world in the middle of a different pandemic.25

In this case, most of the trials that formed the foundation of the government approval and stockpiling of Tamiflu were sponsored by the manufacturer and ghost written by writers paid by the manufacturer. Ironically, those who were listed as principal authors did not have access to the raw data.

The history of Tamiflu also parallels remdesivir, a drug that has little or no positive effect on treatment of COVID.26 Dr. Tom Jefferson is an epidemiologist who works for the Cochrane Collaboration, an organization that collects and reviews medical research findings.

In his presentation at the Symposium about Scientific Freedom in Copenhagen,27 Jefferson described the intricate and complex journey he and his team took to publish the only Cochrane review that was based solely on raw unpublished regulatory data for Tamiflu.

Ultimately, his review demonstrated that the drug shortened the duration of symptoms from flu by less than one day. However, the struggle to obtain the data was nearly as eye-opening as the results.

It took four years for Roche to deliver 150,000 pages of clinical data to Jefferson’s team.28 After getting the data, Jefferson found that although the drug was used worldwide, the WHO had never vetted the raw data, nor had the European Medicines Agency, nor had the CDC.

The FDA had seen the data, however, which prompted them to request a published statement on the label “saying serious bacterial infections may begin with influenza-like symptoms or may coexist with or without complications … but Tamiflu has not been shown to prevent such complications.”29 Jefferson commented: “The FDA was saying, this business about complications, no evidence of that.”

Jefferson also notes that even a decade after the Tamiflu Phase 3 trials were completed, they remained unpublished. From an analysis the team determined:

“there was no convincing trial evidence that Tamiflu affected influenza complications and treatment or influenza infections in prophylaxis.”30

At Least One Pfizer Shot Testing Facility Had Poor Practices

Paul Thacker, investigative journalist from the BMJ, reported on evidence presented by researchers in a Texas privately-owned clinical research lab that the data integrity in Pfizer’s vaccine trial was suspect.31 While this should have been front-page news in 2021, the mainstream media completely ignored it.

According to Brook Jackson, a veteran clinical research coordinator with 20 years of experience, the Pfizer Phase 3 COVID jab trial included data that were falsified, patients who were unblinded and poorly trained people hired to administer the injections. Additionally, follow up on any adverse side effects reported by the participants lagged significantly.

Thacker led the article with the statement: “Revelations of poor practices at a contract research company helping to carry out Pfizer’s pivotal COVID-19 vaccine trial raise questions about data integrity and regulatory oversight.”32

Jackson attempted to inform her superiors multiple times. When her concerns were ignored, she called the FDA and filed an email complaint. Hours later she was fired after working just two weeks. According to her separation letter the management had decided she was “not a good fit” for the company. According to Jackson, this was the first time she’d ever been fired in her 20-year career as a clinical research coordinator.

While the briefing document that Pfizer submitted to the FDA in the application for an emergency use authorization contained no indication of any problems at the lab, Jackson has since provided The BMJ with “dozens of internal company documents, photos, audio recordings and emails”33 proving her concerns were valid.

The BMJ also learned that Jackson’s allegations were supported by others. Months later, Jackson reconnected with employees who were either fired from the lab or who left. One official sent a text message to Jackson saying, “everything that you complained about was spot on.”34

Two other former employees spoke to The BMJ anonymously confirming the broad allegations made in Jackson’s complaint, with one person saying she had worked on more than four dozen trials during her career, but had never experienced the type of work environment at Ventavia on the Pfizer trial.

For example, in several cases there weren’t enough employees to swab the trial participants who were reporting symptoms, even though the trial required lab confirmation of symptomatic COVID-19 as a primary endpoint. The employee called the data produced by the Ventavia lab for the Pfizer trial “a crazy mess.”35

Preprint Data Demonstrate Waning Immunity by March 2021

Doshi also addressed the need for adequate and controlled studies with long-term follow-up before granting approval for vaccinations, most notably the COVID-19 genetic therapy injection.36 In an opinion piece published August 23, 2021, he discussed the updated results that Pfizer had posted for their ongoing Phase 3 COVID-19 vaccine trial.37

Months before, the company had announced the vaccine efficacy was estimated to be “up to six months” after injection.38 While updated results were published one year after the trial began,39 there were not 10 months of data in the follow-up. The paper appeared to be based on the same data included in the April 1, 2021, news release from Pfizer.40

The efficacy results were identical, claiming 91.3% efficacy against symptomatic disease “up to six months of follow-up.” Doshi points out that this matters because it is thus far the most information Pfizer had offered to the public as they were pursuing full approval from the FDA. Both Pfizer41 and the CDC42 have claimed the shot is 95% effective.

Without addressing whether that 95% is absolute or relative risk reduction, or how Pfizer arrived at those claims, it’s also important to note that little can be said about how long vaccine-induced immunity could last when researchers had only measured two months of data.

“Waning immunity” is a known issue for some vaccines, such as the influenza shot.43 Doshi notes44 there have been some studies that found near zero effectiveness only three months after the flu vaccine was administered. The crucial question is the level of effectiveness of the vaccine after an individual is exposed to the virus.

In early July 2021, Israel’s Ministry of Health reported that efficacy against asymptomatic disease fell dramatically in the months following vaccinations. Israel exclusively uses the Pfizer vaccine, which Pfizer’s chief scientific officer, Philip Dormitzer, told a Zoom meeting:45

“Early in the pandemic we established a relationship with the Israeli Ministry of Health where they used exclusively the Pfizer vaccine and then monitored it very closely, so we had a sort of laboratory where we could see the effect.”

Only 7% of Trial Participants Reached 6 Months of Data

Data released from Israel show the efficacy fell to 64% over one month from June 6, 2021, to July 5, 2021.46 By late July, the efficacy had dropped dramatically again to 39%.47 While these numbers are low, the FDA’s expectation is that any approved vaccine should be at least 50% effective.48

Starting in December 2020, Pfizer unblinded the majority of the participants in the trial and allowed the placebo group to get vaccinated. By March 13, 2021, 93% of those participating in the Pfizer trial had been unblinded. This means the reference to six months of safety and efficacy in the preprint paper reports on only the 7% of trial participants that reached six months of the blinded follow up.

While the paper was published one year after the trial began, the data reported do not go past the first six months, which is the time period in which Israel reports efficacy dropped to 39%. Doshi goes on to say:49

“It is hard to imagine that the <10% of trial participants who remained blinded at six months (which presumably further dwindled after 13 March 2021) could constitute a reliable or valid sample to produce further findings. And the preprint does not report any demographic comparisons to justify future analyses.”

Although claims have been made that the vaccine prevents severe disease, the trials were not designed to study severe disease, which Doshi details in another paper published in The BMJ.50 In the opinion piece published in The BMJ, Doshi writes:51

“But here we are, with FDA reportedly on the verge of granting a marketing license 13 months into the still ongoing, two-year pivotal trial, with no reported data past 13 March 2021, unclear efficacy after six months due to unblinding, evidence of waning protection irrespective of the Delta variant, and limited reporting of safety data.”

Coincidentally, the very day Doshi’s paper was published in The BMJ, the FDA announced approval for the Pfizer COVID-19 shot being marketed as Comirnaty.52

Yet, without adequate data analysis, and with mounting numbers of adverse events reported to VAERS,53 the FDA still expanded eligibility for the jab to include children 12 years and older to receive a single booster dose and approved emergency use authorization for children 5 years old and older.54 Doshi ends with a reasoned and logical call to action to the FDA:55

“FDA should be demanding that the companies complete the two-year follow-up, as originally planned (even without a placebo group, much can still be learned about safety). They should demand adequate, controlled studies using patient outcomes in the now substantial population of people who have recovered from covid. And regulators should bolster public trust by helping ensure that everyone can access the underlying data.”
