"This paper summarizes the mode of action of mRNA vaccines, as well as three potential pathogenetic mechanisms that may account for the toxicity observed with the mRNA vaccines against COVID-19, namely: chemical toxicity of lipid nanoparticles, direct toxicity of the spike protein, whose expression is induced by the vaccines, and the destructive effects of the immune response to the spike protein. The case is made that of these mechanism the third is likely the most important one. If this conclusion is correct, then essentially the same level of toxicity must be expected with future mRNA vaccines against any other pathogenic microbes."
