What are COVID-19 mRNA vaccines? Science to help debunk myths

There seems to be a lot of confusion about how the new COVID-19 mRNA vaccines from Pfizer and Moderna. The purpose of this article is to give the casual reader a 15 minute (plus or minus an hour) scientific review of the mRNA technology that is the basis of those new vaccines. 

There will be several new COVID-19 vaccines that should be available widely in the next few weeks, but none of those will use mRNA vaccine technology. When those become available, I’ll try to write up a similar review of those technologies.

Let’s give this a go.

Lipid nanoparticles in COVID-19 mRNA vaccines are safe – ICAN is wrong

This article about lipid nanoparticles in COVID-19 mRNA vaccines is by VaultDwellerSYR, a pseudonym used by a faculty member of a School of Pharmacy within a large medical school. They have significant research and publications on the effect of certain chemicals on the brain. Although we are opposed to all arguments from authority, the author has a substantial record of actual, published research in the fields of brain cell biology and biochemistry. 

The anti-vaccine Del Bigtree‘s Informed Consent Action Network (ICAN), as expected, started to seed doubts and fallacious claims on COVID-19 mRNA vaccines, in an attempt to discredit and reduce the uptake of this vaccine by the population.

In their latest stunt, ICAN posted on January 17th on their Facebook page the following statement with a “legal update” pictogram:

ICAN INQUIRES WITH THE FDA ABOUT THE SAFETY OF LIPID NANOPARTICLES USED IN PFIZER’S AND MODERNA’S COVID-19 VACCINESICAN, through its attorneys, has once again written to Dr. Peter Marks, Director of the FDA’s Center for Biologics Evaluation and Research, to demand a response to the question of whether or not lipid nanoparticles used in both of the currently authorized COVID-19 vaccines are safe. 
ICAN is aware that both Pfizer and Moderna have used lipid nanoparticles (“LNPs”) in their vaccines – LNPs are what the manufacturers use to surround the RNA so that it does not fall apart when injected and before reaching its target cells. Some have compared these LNPs to a fatty envelope or a delivery vehicle to get the mRNA into the human body in one piece.

A concern arose when ICAN was alerted to a study published in 2018 titled Lipid Nanoparticles: A Novel Approach for Brain Targeting. The study states: “…lipid nanoparticles are taken up readily by the brain because of their lipophilic nature. The bioacceptable and biodegradable nature of lipid nanoparticles makes them…suited for brain targeting.” The article also states, “these nanostructures need to be investigated intensively to successfully reach the clinical trials stage.”
ICAN wants to fully understand whether the evidence that these LNPs are easily taken up and end up in the brain is a safety concern with these two particular vaccines. ICAN, through its attorneys, led by Aaron Siri, has therefore sent a letter to Dr. Peter Marks, the Director of the Food and Drug Administrations’ Center for Biologics Evaluation and Research. If you recall from previous legal updates, Dr. Marks has referred to himself as “the FDA point person on COVID-19 vaccines” and has assured Americans that the FDA “will make sure they’re safe and effective.” 

ICAN also pointed out to Dr. Marks that there appears to be support for the proposition that the body may react strongly to a second dose of the LNPs. Stated differently, the body is primed to have an immune reaction to the LNPs with the first dose. As explained by Johns Hopkins, “Side effects were more frequent after the second dose in the vaccine trials.” Another article, titled Exogenous nanoparticles and endogenous crystalline molecules as danger signals for the NLRP3 inflammasomes, supports that the increasingly inflammatory side effects observed in those who received the vaccine in Pfizer’s and Moderna’s clinical trials are attributable to the LNPs and that these side effects get worse with repeated injection. We have seen this increased “reactogenicity” clearly in the data from both Pfizer’s and Moderna’s COVID-19 clinical trials. 
ICAN continues to ask the hard questions of Dr. Marks and others: If LNPs from the vaccine, which contain mRNA, are entering brain tissue, and an immune reaction is occurring during the second dose to these LNPs, does this pose a safety concern for vaccine recipients? ICAN asked Dr. Marks to consider the question posed and provide support for the substance of any response he provides.

ICAN will closely review any response from Dr. Marks given his promise that he and the FDA “uphold globally respected standards for product quality, safety, and efficacy” and his statement that he would resign if “something that was unsafe or ineffective [] was being put through.” As always, ICAN offered to provide any additional information or to meet with Dr. Marks to discuss this issue.

As you can see, ICAN is on another one of their PR stunts in the attempt to “cease and desist”, as intimidation with little legal merit and certainly not based on an honest and critical review of the existing literature. Let’s critically examine ICAN’s claims about lipid nanoparticles.
