Current state of knowledge on the excretion of mRNA and spike produced by anti-COVID-19 mRNA vaccines; possibility of contamination of the entourage of those vaccinated by these products

Abstract

The massive COVID-19 vaccination campaign is the first time that mRNA vaccines have been used on a global scale. The mRNA vaccines correspond exactly to the definition of gene therapy of the American and European regulatory agencies. The regulations require excretion studies of these drugs and their products (the translated proteins). These studies have not been done for mRNA vaccines (nor for adenovirus vaccines). There are numerous reports of symptoms and pathologies identical to the adverse effects of mRNA vaccines in unvaccinated persons in contact with freshly vaccinated persons. It is therefore important to review the state of knowledge on the possible excretion of vaccine nanoparticles as well as mRNA and its product, the spike protein. Vaccine mRNA-carrying lipid nanoparticles spread after injection throughout the body according to available animal studies and vaccine mRNA (naked or in nanoparticles or in natural exosomes) is found in the bloodstream as well as vaccine spike in free form or encapsulated in exosomes (shown in human studies). Lipid nanoparticles (or their natural equivalent, exosomes or extracellular vesicles (EVs)) have been shown to be able to be excreted through body fluids (sweat, sputum, breast milk) and to pass the transplacental barrier. These EVs are also able to penetrate by inhalation and through the skin (healthy or injured) as well as orally through breast milk (and why not during sexual intercourse through semen, as this has not been studied). It is urgent to enforce the legislation on gene therapy that applies to mRNA vaccines and to carry out studies on this subject while the generalization of mRNA vaccines is being considered.
