Dr. Gregory Michael — what happened after he got the COVID vaccine?

Dr. Gregory Michael, MD, a Miami, FL OB-GYN, died a little over two weeks after receiving the COVID-19 vaccine. Almost everything that happens after someone gets this new vaccine is under the microscope by just anyone that has an interest in vaccines.

Of course, anti-vaxxers jumped on the bandwagon after reading that Dr. Gregory Michael’s wife stated that he died because of the vaccine. Similar to the story about Tiffany Dover, who fainted soon after being vaccinated because she had a fear of needles and, of course, did not die, the anti-vaccine forces are doing everything they can to discredit the vaccine.

Dr. Michael was one of our brave healthcare workers who delivered babies during a pandemic. He was pro-vaccine, and that’s why he received the COVID-19 vaccine.

Let’s take a close look at what happened to Dr. Michael. Is there a correlation to the COVID-19 vaccine? Did the vaccine cause his death?

You cannot boost your immune system – except with vaccines

COVID-19 has been a windfall for quacks who think that they have the secret power to boost your immune system. The problem for these scam artists is that there really is no way to boost the immune system – well, vaccines do that, but they are targeted to single pathogens, like varicella-zoster virus or SARS-CoV-2.

The problem with these immune system myths is that they overlook or ignore a basic physiological fact – the immune system is a complex interconnected network of organs, cells, and molecules that prevent the invasion of hundreds of thousands, if not millions of pathogens and other antigens every single day. In fact, the immune system works almost perfectly all the time – when it doesn’t, it’s because of a chronic disease or condition, not because you haven’t swallowed a bottle of vitamin C.

And no matter how much individuals try to trivialize the complexity of the immune system, it does not make it so. If it were easy as downing a handful of supplements or the magical blueberry-kale soy milk smoothie for boosting immunity to the novel coronavirus or any other disease, every physician in the world would prescribe it.

Unfortunately, even if we could boost our immunity, we shouldn’t – a hyperactive immune system is frequently dangerous to an individual.

The problem with the quacks is that they don’t know any of the science of the immune system, and they make money when they think you don’t.

This article will try to explain the immune system and how to keep it running effectively without buying the overpriced pseudoscience you might find on the internet or your local Whole Foods. So, I’m going to save you some money and give you confidence in the power of your own immune system.

Acute disseminated encephalomyelitis is not linked to the HPV vaccine

A recent case report about a death of a 15-year-old boy from a form of acute disseminated encephalomyelitis (ADEM) after receiving the quadrivalent HPV vaccine has been widely shared by anti-vaccine groups. Of course, I wanted to look into any potential link between ADEM and the HPV vaccine.

Before I start looking at the evidence, I must point out that case reports have little meaning in the hierarchy of vaccine research. To be honest, case reports, even if they’re published in high-quality journals, barely rise above anecdotes as evidence. Why? They are nothing more than a report without being able to establish causality. But most importantly, they represent an n=1 research population, which tells us little. And it doesn’t show correlation, let alone causation.

We’ve also discussed ADEM before – the tragic story of Christopher Bunch whose mother blamed the HPV vaccine for causing his ADEM.

Setting that aside, is there any evidence that shows any link (or lack of a link) between acute disseminated encephalomyelitis and the HPV vaccine? Let’s take a look at this evidence.

NVICP compensation and autoimmune syndromes – vaccine court review

brown wooden gavel on brown wooden table

This article about NVICP compensation and autoimmune syndromes was written by Dorit Rubinstein Reiss, Professor of Law at the University of California Hastings College of the Law (San Francisco, CA), who is a frequent contributor to this and many other blogs, providing in-depth, and intellectually stimulating, articles about vaccines, medical issues, social policy, and the law.

Professor Reiss writes extensively in law journals about the social and legal policies of vaccination. Additionally, Reiss is also a member of the Parent Advisory Board of Voices for Vaccines, a parent-led organization that supports and advocates for on-time vaccination and the reduction of vaccine-preventable disease. She is also a member of the Vaccines Working Group on Ethics and Policy.

This post examines the treatment by the National Vaccine Injury Compensation Program (NVICP) of the second of two claims (see first one here) heard from those claiming vaccines cause more injuries than acknowledged in recent days. This article will focus on NVICP compensation and autoimmune syndromes.

The Special Master’s decisions – as many decisions in NVICP are – are long, complex, and examine the evidence closely and in detail. They address factual debates, expert disagreements specific to the case, and expert disagreements on the science.

This post won’t cover them – that’s not my goal. All I will address are the Special Master’s conclusion about two hypotheses raised by those who believe vaccines injured their child (and also promoted by anti-vaccine organizations).

Vaccines cause diabetes – another myth refuted and debunked

If you cruise around the internet, engaging with the anti-vaccine religion (not recommended), you will pick up on their standard tropes, lies, and other anti-science commentaries, like the claim that vaccines cause diabetes. Of course, once one digs into the scientific facts, you find little supporting evidence.

A lot of the vaccine deniers believe that vaccines cause a lot of everything and several claims that vaccines cause Type 1 diabetes (or here), based on little evidence. As far as I can tell, this myth is based on the “research” from J. Barthelow Classen, M.D., who has pushed the idea that vaccines cause type 1 diabetes, through some magical process that has never been supported by other independent evidence.

In another example of the anti-vaccine zealot’s cherry-picking evidence to support their a priori conclusions, they ignore the utter lack of plausibility supporting any link between vaccines and Type 1 diabetes. At best, Classen has cherry-picked statistics to support his predetermined conclusions, “comparing apples to oranges with health data from different countries, and misrepresenting studies to back his claim.”

Moreover, Classen seems to come to his beliefs based on population-wide correlations that rely on post hoc fallacies, rather than actually showing causality between vaccines and diabetes. It’s like finding that a 5% increase in consumption of Big Macs is correlated with a full moon. Those two things may happen at the same time, but it would take a laughable stretch of real science to make a cause for causality.

Reverse type 1 diabetes mellitus with BCG vaccine – promising results

A clinical trial that examined the potential of the bacillus Calmette-Guerin vaccine, or BCG vaccine, to reverse even advanced type 1 diabetes mellitus was recently published in a Nature journal. In addition, researchers proposed a possible mechanism describing how the BCG vaccine may enhance the immune system and could stop and reverse the damage that leads to diabetes. But does this constitute evidence that this vaccine can really reverse type 1 diabetes? Spoiler alert – I’m not fully convinced, but my interest is piqued.

The BCG vaccine was initially developed to prevent tuberculosis. It is one of the oldest vaccines available on the market, first used in 1921 (pdf). With the successful eradication of tuberculosis in many countries, the vaccine isn’t used very much anymore, except in countries with endemic tuberculosis.

Let’s take a look at what we know about diabetes, how the BCG vaccine might be able to reverse type 1 diabetes mellitus, and what the new article reports. Continue reading “Reverse type 1 diabetes mellitus with BCG vaccine – promising results”

Autoimmune diseases unrelated to HPV vaccine – new Canadian study

There are so many outlandish and unsupported claims about the HPV vaccine, it’s difficult to keep up with them all. One of the most outrageous lies about the HPV vaccine is that it causes autoimmune diseases, despite the robust epidemiological or clinical evidence that firmly establishes the safety of the HPV vaccine, especially with respect to autoimmune diseases.

Autoimmune diseases are conditions where the immune system has an abnormal response to normal cells in the body. Celiac disease, type 1 diabetes mellitus, multiple sclerosis, and many other conditions are as a result of an autoimmune disorder. We don’t know what causes the autoimmunity, but there is almost no biological plausibility that any vaccine could induce the disease.

Despite the lack of a reasonable biological mechanism leading from the HPV vaccine to any of the multitudes of autoimmune diseases, the anti-vaccine forces continue to try to establish a link. For example, Yehuda Shoenfeld has pushed a ridiculed hypothesis that the vaccine causes something he calls autoimmune syndrome induced by adjuvants (ASIA). Not a single respected scientist buys into ASIA, and Shoenfeld has presented no vigorous clinical or epidemiological evidence supporting its existence.

Not to pile onto the anti-vaccine tropes about the vaccine, but a large, and new, Canadian study has once again shown us that there are no links between the HPV vaccine and autoimmune diseases. This adds to the body of evidence that, for real science, reinforces the conclusion that the HPV vaccine is an incredibly safe vaccine.

Boosting the immune system – that’s what vaccines do

Immune system myths are one of the common claims of the junk medicine crowd, especially the anti-vaccine activists. The pseudoscience of the immune system is pernicious and possibly dangerous.

It’s frustrating that the pseudoscience from the junk medicine crowd claims that this supplement or that food is critical to boosting the immune system – hang out for a day on Facebook, and you’ll probably see way too many memes saying that all you have to do to boost your immune system is eat a blueberry kale smoothie. I still see that dumb banana claim that it cures cancer.

And no matter how much individuals try to trivialize the complexity of the immune system, it does not make it so. One can claim all day long that downing a few tablets of echinacea will boost the immune system to prevent colds (it doesn’t), it doesn’t make it scientifically accurate. Nor does it create an accurate description of the immune system.

Vaccines cause multiple sclerosis? No link found in a large scientific review

There are so many anti-vaccine religious tropes about the safety of vaccines, that it is often hard to keep them all straight. One of the current ones is that vaccines cause autoimmune diseases such as multiple sclerosis. Does scientific evidence support the hypothesis that vaccines cause multiple sclerosis?

Well, I have written about whether vaccines cause multiple sclerosis before, and based on the scientific evidence (see here and here), there simply was no link between them. Of course, with the anti-vaccine religion, evidence be damned, they will stand by their claims. All I can do is repeat myself with more and more evidence, refuting their claims.

There is a new review of the evidence of whether vaccines cause multiple sclerosis, and once again, they found nothing. And once again, I will review the evidence to see if there is something to the claims of the anti-vaccine religion. I should give a spoiler alert, but you all know what’s coming.
