Vaccine Disinformation Moves To Congress

 “War is peace.
Freedom is slavery.
Ignorance is strength.”
―George Orwell, in 1984

“Opinion is science.”

That silly notion can now be added to the Orwellian Newspeak Catechism thanks to those who prefer confirmation bias over empirical data to determine their “alternative facts.” This seems to include certain members of Congress.

The war on objective science recently spilled over to Congress where a group of anti-vaccine Congressmen and women and one Senator held an impromptu meeting to confirm their disinformation about so-called injuries caused by the COVID mRNA vaccines. This was not a meeting called by a regular committee but an ad hoc gathering of some anti-vaccine rogues. It was held in a tiny back room in the Capitol and was poorly attended, poorly staffed, poorly equipped, and, thankfully, poorly publicized. It was described as a meeting of the “shadow Congress;” accurately named as it dabbled in the penumbra of truth.

Leading this November 13 meeting was Marjorie Taylor Greene (R, Georgia). Greene, no stranger to fantasy, has claimed that Jewish space lasers caused recent wildfires in California, that the shootings in Parkland, Sandy Hook and Las Vegas were staged, and that 9/11 was an inside job. Because of these and other extremist reflections, the House sensibly stripped Greene of several committee assignments.

Others on the “committee” included Clay Higgins (R, Louisiana), Thomas Massie (R, Kentucky), Warren Davidson (R, Ohio), and Andy Biggs (R, Arizona). Also attending was Senator Ron Johnson (R) from my own State of Wisconsin who has been a vaccine dissembler for a while, claiming, for instance, that the vaccines have killed many people. I recently contacted the Senator’s office and asked why he believed that. They quickly responded and sent me to a web site that was very professional looking and had very many graphs and tables claiming to show that the vaccines caused hundreds of thousands of deaths. The problem is that the data they used to put said graphs and tables together were bogus. The statistics were fraudulent (for example to test the site, an MD submitted a claim saying that the vax turned him into the Incredible Hulk. His claim was accepted!), and the website itself had been debunked numerous times by the investigative press and in science journals for incorrectly reporting the data. I pointed this out to Sen. Johnson’s office and never heard back, in contrast to their earlier quick response. Go figure.

Back to the Shadow Congress Committee meeting: Three people testified: A lawyer, an obstetrician-gynecologist, and a scientist. A summary of the testimony of each, with my comments follows.  

The lawyer. Forty-six-year-old Thomas Renz, went first. He passed the Ohio bar exam in 2019 after five tries and since has made a name for himself, along with the MyPillow guy, Mike Lindell and others, as a COVID conspiracy buff. Renz made three claims enumerated below: 

  1. First, Renz declared without any evidence, “The people that are dying are vaccinated.” However, a study published in the Journal of the American Medical Association showed that in 2021, unvaccinated adults were 12 times more likely to be hospitalized and in 2022, that they were 6 times more likely to die after infection. Science shows that COVID vaccines have been estimated to have saved the lives of more than 3 million Americans. Renz’s says otherwise. Who are you going to believe, science or the lawyer, Renz?
  2. The lawyer also claimed, again without proof (a lawyer without evidence?), that “COVID is not as bad as SARS or MERS but about as dangerous as a bad flu season.” Well. The first human coronavirus outbreak, SARS-1, was identified in Asia in February 2003. It infected a bit more than 8,000 people, killing ~800. By July 2003, the outbreak was contained without a vaccine. The second coronavirus outbreak, called MERS (Middle East Respiratory Syndrome), appeared in June 2012, in Saudi Arabia. That virus infected >2,500 people, killed about 900 and also was contained in a short while without a vaccine. Compare those numbers to SARS-CoV-2, which so far has killed almost 2 million people in the United States and 7 million people in the world. And 3+ years later it continues; it is not contained even though we have several vaccines. Except for the 1918 flu pandemic, which killed more than 50 million people worldwide (before there was a vaccine for flu) COVID is worse than any other flu in history. Renz’s lawyerly opinion is bunk. Why is he even testifying on a medical matter?
  3. Renz saved the best for last. With the help of an “unnamed whistleblower,” Renz claimed, without proof, of course, that something suspicious happened in November 2014 at Fort Riley, Kansas, when the Department of Defense (DOD) and the CIA, in collaboration with the Wuhan Institute of Virology, created SARS-CoV-2 virus. Not in the Wuhan lab mind you, but in Kansas in 2014! To support his claim, Renz offered nothing! It was his opinion. Renz also asserted that Tony Fauci, the CDC, FDA, and the DOD played a part in a massive cover-up of this (so how does HE know?). He unbelievably stated that Hunter Biden was also involved (why not?). Funny how the CIA or FBI hasn’t picked up on any of that. Renz knows because he says he does. Trust him, he’s a lawyer without evidence. But that is good enough for the Shadow Congress.

The Ob/Gyn. Next up was Kimberly Biss, MD, a well credentialed obstetrician and gynecologist practicing in Tampa Bay and St. Petersburg, Florida, which makes her testimony all-the-more-difficult to understand.

She claimed that after receiving COVID vaccines, an unspecified number of women in her practice suffered unsubstantiated menstrual cycle irregularities including severe, persistent bleeding. However, the only way to reliably determine whether COVID vaccines caused these  changes in menstruation is to compare the symptoms in women who did and didn’t receive the vaccine. She didn’t do this. Anecdotal observations like these offered by Biss usually don’t include both groups, which is why medical science considers anecdotes to be unreliable and instead rely on controlled clinical trials.

Furthermore, real scientific comparisons between vaccinated and unvaccinated women have been done but these were not entered into evidence at the Shadow Congress Hearing. A study of more than 1,100 women performed by the Boston School of Public Health found that there was no association between COVID-19 vaccination and cycle irregularity, bleed length, heaviness of bleed, or menstrual pain. So, which is more credible, Biss’s personal anecdote on an unknown number of patients whose medical history is unknown vs a controlled scientific study on over 1000 patients with carefully documented medical histories and compared to a comparable cohort of unvaccinated menstruating women?  

Biss further testified that her practice miscarriage rate went up in vaccinated women, again without indicating the number of patients she saw and without providing any medical documentation. She again failed to note the miscarriage rates in unvaccinated women (why does she always leave out the data from unvaxed women? Perhaps her practice should be scrutinized!). A scientific study of 40,000 pregnant women, showed that vaccination was not at all associated with an increased risk of premature births. And other controlled studies have shown that COVID vaccination during pregnancy does not increase the risk of birth defects. Again, what would you believe Biss’s anecdote or several well controlled peer-reviewed and published science studies?

Biss continued her misleading anecdotal testimony by claiming that it was unsafe for vaccinated women to breastfeed because she heard it caused myocarditis in babies in Scotland. She failed to provide any substantiation for her wild claim that no one else seems to know about. Not only has breastfeeding proven to be safe in women who have received COVID vaccines, newborn infants benefit from vaccine-induced antibodies in breast milk. it provides newborns with their initial protection against COVID as they develop their own immune system. That is a normal part of the maternal-fetal immune system that newborns immensely benefit from. That is basic immunology.  

Finally, and most outrageous was Biss’s stance on vaccinating children. She advised against vaccinating kids falsely claiming that only “three in one million children will die from COVID.” One wonders where she gets her facts like this and like those about myocarditis in breast fed babies in Scotland. As of January 2023, COVID was the leading cause of infectious disease deaths in children. Contrary to Biss’s claims, the COVID death rate for children less than one year of age was 43 per million. Hundreds of young children have died from COVID and many, many more have been hospitalized long term with the very serious condition called multisystem inflammatory syndrome, or MIS, which I have written about in these pages. COVID is much more serious than the flu for kids. None of those deaths or serious illnesses in kids are acceptable. Her claims to the contrary are simply irresponsible for a physician to make.

Finally, the scientist. Perhaps the silliest testimony in front of MTG’s “shadow” committee came from a scientist and physician named Robert Malone who recently has gone around claiming he “invented” the mRNA vaccine. He did not. In the late 1980s and early 90s, labs around the world were fixated with the idea of trying to express genes in cells via transferring single gene sequences into cell cultures. The technique was called “transfection.” It promised to be a powerful tool for studying the function of genes in cells, but proved enormously difficult as I wrote about earlier. My own lab considered trying it, but discarded the idea in favor of another approach, viral-based gene transfer, which we often used to study gene function, and which some might call routine gain-of-function research as I described earlier in these pages.

Meanwhile, Malone was a small part of the “transfection” bandwagon and in the late 80s published two papers showing it was possible to transfect fragile mRNA protected by a lipid micro-bubble into cells (most labs transfected DNA, which was easier to work with than mRNA). Undoubtedly, his research represented a stepping stone on the path to developing the vaccines, but he had no role in vaccine development. He was one of very many scientists who contributed incremental advances that ultimately made the vaccines possible. He is now way overselling his role. The mRNA technology that produced the vaccines recently won a Nobel Prize and Malone was never mentioned in the invention. He is only a giant in his own mind.

More to the point, Malone testified that the vaccines are contaminated with fragments of DNA and dangerous. He argued, without evidence and contrary to all other science, that these DNA fragments alter cellular DNA of vaccine recipients, causing cancers, autoimmune diseases, and a variety of other disorders. For pregnant women, Malone further opined, again without a shred of proof and contrary to common science, that these DNA fragments could cross the placenta and cause birth defects. Furthermore, according to Malone, the FDA, the CIA, and other government agencies know about this DNA contamination but are covering it up (is Hunter involved in this too??). Again, he offered no evidence at all for this allegation. But, maybe we can excuse him, because there is no evidence to offer.

The idea that the vaccines are contaminated with DNA detritus is old news. All vaccines contain DNA of different sorts, which has never caused any harm as long as vaccines have been given. In fact it is biologically impossible that miniscule amounts of DNA detritus could mess up our cellular DNA. It is irresponsible, and scientifically ignorant of Malone to simply throw this out without elaborating. He didn’t elaborate because to do so would have ruined his “Frankenscience” innuendo that seemed to duly impress the scientifically naïve Shadow Congressional audience he spoke to.

The mRNA used in the vaccine is produced from a DNA strand. The DNA strand is then digested with an enzyme called DNase which chews up all DNA strands, leaving only the DNA building blocks, or remnants of it behind; DNA detritus. It is like taking a large building and demolishing it into its brick, nails, planks, and broken pieces. The large mRNA molecules are then easily biochemically separated from most of the DNA detritus. Even if there were traces of DNA detritus left over, it is biologically impossible for it to damage cellular DNA. It simply is recycled and reused by our cells.

Maybe larger, intact DNA fragments could mess up our cellular DNA? In extremely rare circumstance some viruses like HIV have a special enzyme that could allow that to happen but you have to be infected with that sort of virus, which is quite rare. We are exposed to large fragments of DNA all the time with no adverse effects. Consider the following two points: 1) we eat foreign DNA from plants and animals all the time and that DNA enters our blood stream in intact pieces much larger than the digested detritus we have been talking about. Yet, we are totally unaffected by this. 2) We also get vaccinated with whole DNA virus vaccines and have no concern that they affect our cellular DNA. Studies have shown that there is NO genotoxic effect of any of the vaccines.

Finally, consider the inherent conflict in Malone’s position. On the one hand he goes around promoting himself as the inventor of the vaccine technology. He even laments that he has not been given his due credit for the invention. Then he tries to discredit the same invention as something very dangerous and that should not be given to people because it causes enormous harm.

Which is it? Do we laud Malone as he would like for discovering a lifesaving vaccine, or pillory him for creating the dangerous vaccine he says it is? The man is as confused as his testimony.

This is what some of our Congress people spent their time doing last November. The Congressional Flake Caucus wasting their time and our money on a "hearing" without a single reputable testimony. At least it received the very little attention it deserved.

Last word. In an earlier post I asked the question if it was criminal to intentionally mislead people about lifesaving vaccines. I raise the question again, now.


While SARS-CoV-2 And Our Immune Systems Do A Dance, We Get Re-Infected

Note: Artificial intelligence wrote nary a word of the following article, which was fully composed by the natural intelligence of a certain human.

Your sometimes humble blogger remembers how immunology science first beguiled him. It was during senior year in high school in the Virginia suburbs of Washington, DC. More specifically it was during a lunch break while working at a People’s Drug Store that had a lunch counter. Your then nascent blogger grabbed the recent issue of Scientific American from the magazine rack and opened it to an article that was way above his green scientific understanding but, he, nevertheless, gleaned from the article that the immune system could make antibodies to just about any molecule in the universe, even ones newly created in a lab that the universe had never seen. Amazing!

Your immune system would also make antibodies against the cells and tissues of your best friend and everyone else in the world, and vice versa, but you and your best friend, et al., would not make antibodies against the same cells and molecules in your own bodies! What?

“Holy cow!” I thought. How in the world can the immune system do all that? How can it respond to something the world had never seen and secern friend from foe? At that moment, at that lunch counter over a burger, Coke and an article I barely understood, an immunologist was made. And I did indeed go on to earn a PhD in immunology and I indeed have studied how the immune system recognizes viruses and have done vaccine research. What a pivotal lunch break that was for me.

The question about antibody discrimination clearly fascinated me. That mystery has been solved and a few Nobel prizes awarded for its elegant solution, but related spin-off questions about how antibodies protect us keep coming up in different ways. It did so most recently during the COVID pandemic. Why weren’t the antibodies we generated via vaccination or via natural infection more protective against subsequent infection? In a twist in the plot of biology, it turns out that we have learned that the answers to these questions center around a complicated dance performed between both the virus and immune biological systems.

Biology is so doggone interesting!!

COVID Vaccine generated immunity: The several vaccines we now have against the SARS-CoV-2 virus are effective and provide examples of how vaccines are very good at getting the immune system to respond to what it detects as foreign invaders. But the vaccines are just designed to tell our immune systems to make antibodies against just a very small fragment of the spike protein. In contrast, the virus is constructed of several large proteins each of which has many different regions that the immune system can separately recognize as foreign. In other words, if the virus is like a brick building, your system theoretically can make a different antibody that specifically recognizes each brick of the building. So, the vaccine is like exposing the immune system to about 2-3 bricks of the whole building and trusting the resulting immune response against those few bricks to bring the whole building down.

The immune system was very good in generating antibodies to a small portion of the virus, yet many vaccinated people still were infected and caught COVID. Does that mean, as many vax naysayers claim that the vaccines were ineffective? Not at all, as I have discussed here before. While the CoV-2 vaccines did a good job at protecting against serious disease and death they were not very good at preventing the spread of the virus. These vaccines effectively generated a systemic immune response, meaning that you had anti-viral antibodies circulating in your blood, which did do a very good job preventing serious disease once the virus got inside you. But, it still got inside. You still got infected and got mildly sick.

We now know that the virus enters via mucous membranes in your nose, sinuses, mouth, throat and eyes. It has to first cross mucous membranes in order to infect you and that is where it needs to be stopped in order to actually prevent infection and further spread to others. The problem is that mucosal immunity is caused by a different type of antibody than what circulates in the blood and by what is generated by a typical vaccine that is given by an injection in the arm. To generate mucosal immunity, you need a vaccine that you spray in your mouth or nose, which then should generate the type of antibodies that provide mucosal protection and better protect you from infection via that route and better prevent the virus from spreading through a population.

At the beginning of the pandemic, we were faced with a brand new pathogen for which we knew nothing about how it behaved or how it infected and spread between people. At that point, we reasonably chose to quickly make the most common type of vaccine--a shot. While it didn’t fully protect against getting infected, it nevertheless was very effective at protecting against serious disease. So, it did a good job. Current efforts are underway to develop a mucosal vaccine. But, we must also deal with other complications we have learned about the dance between the virus and the immune system to make sure that vaccine will be maximally effective at preventing infection. Read on.

“Natural” COVID immunity: As it became clear that vaccinated people were still getting infected, the vaccine dissenters and dissemblers proclaimed loudly, and still do, that the vaxes failed miserably. They ignored the survival data and only focused on the infection data. They then began touting “natural immunity,” which is the immunity one usually gains after being naturally infected. But, that can be uncertain given the fact that the route of infection and the dose of virus can vary wildly and confer different levels of protection, as I reported earlier. Plus, with natural infection, one runs the risk of serious disease and death from the disease.

Then, to the chagrin of the “natural immunity” enthusiasts it turned out that they also were getting re-infected! And this re-infection occurs despite the fact that natural immunity occurs after infection across the mucous membranes that should, as discussed above, generate an immune response that would stop an infection! This is the dance.

Therefore, we now know that neither vaccine immunity, nor infection immunity fully protects against future infection with the CoV-2 virus (there is partial protection, but I won’t go into that here).

As we learned as recently as last April, from a Harvard study published in the journal Science, despite the fact that a natural infection presents the immune system with the full viral “building and all its bricks” potentially recognizable by antibodies, it turns out that only a few of the “bricks” are in fact actively “seen” at any time by the immune system.

This immuno-dominance of a small part of a larger pathogen that has thousands of sites or bricks the immune system can recognize is not unusual. It is like a large building consisting of thousands of bricks, but having a very attractive window that draws your attention. While you know an entire building is there, your attention is mostly drawn to the window. So can the focus of the immune system be preferentially drawn to a small part of a larger edifice. The immune system is perfectly capable of seeing the rest of the “building,” but it prefers to direct its attention to a small part of it. However, if you take away the part it prefers to focus on, the immune system will easily recognize something else. This immuno-dominance in what the immune system “sees” has several causes that are way too complicated to go into here without writing a textbook (an interested reader might try Paul’s Fundamental Immunology. My rather old edition of that book runs about 1500 pages!). Suffice it to just know that this sort of immuno-dominance often happens where only a small part of a large pathogen is preferentially recognized by the immune system.

Thus, the immunity developed after a natural infection is mostly only directed at a small portion of the virus, much like the antibody response after vaccination with just a small part of the virus. The natural immune response, like the vaccine immune response, is robust and effective, yet both are only directed against a very small portion of a big pathogen, and both are very leaky in that one can still get infected again! What gives?

Mutation gives.

How the virus escapes immunity: The SARS-CoV-2 virus is highly mutable unlike the other viruses like polio and small pox we vaccinate against and maintain long term immunity against. Thus, the virus quickly mutated, or changed, the “bricks” against which the vaccines were made rendering the immune response less and less effective over time as new viral iterations appeared. That is why the many boosters we got were necessary to keep vaccination immunity up with viral changes.

And that also is how someone who became immune after natural infection also became re-infected. The virus did a two-step and mutated the small region recognized by the immune system. It was pretty easy for the virus to do since it only had to change a couple of “bricks” in its facade that the antibodies were mostly attacking. That means that upon re-infection with a slightly mutated virus, the immune systems have to be re-educated to recognize a new intruder, and that takes time, which allows a new infection to settle in. Thus, in this dance, the gentleman virus leads and the dame immune system follows.

New vaccines continue to be developed that scientists hope will solve these problems unique to SARS-CoV-2. Most of the new vaccines are being built on the mRNA platform, but using novel approaches to 1) develop vaccines that can be given as a nasal spray in order to generate the mucosal immunity that hopefully would be more effective at actually preventing COVID. If this works, it might even be possible to hinder COVID spread. 2) But in order to block CoV-2 spread on a population level, we need to find other regions of the virus that are not so highly mutable. These would conceivably be regions of COVID proteins critical for viral function that tolerate little change in structure because that change would destroy the proteins' critical function and essentially kill the virus. Alternatively, new vaccines could incorporate multiple "bricksl" from different regions of the edifice assuming that it would be nigh impossible for all those sites to simultaneously mutate. If such regions are accessible to the immune system, then the resulting immunity would be expected to be impervious to viral mutation, thus ending the dance on a sour note.

It is even possible that such a vaccine could protect against a wide range of coronaviruses, thereby preventing future health problems arising from new coronaviruses. Remember SARS that also popped up in China a couple of decades ago? That virus has some genome similarity to the virus that caused the COVID pandemic, and both are distantly related to the virus that caused MERS that arose in the Middle East. If a pan-coronavirus vaccine can be developed, it could feasibly prevent many future epidemics and pandemics.

We shall see.

This is all part of a new biology that I earlier dubbed BioX. Biology is so doggone interesting!!
