The technology used in Moderna’s COVID-19 vaccine carries toxicity risks, scientists with the company said in a new paper.“A major challenge now is how to efficiently de-risk potential toxicities associated with mRNA technology,” the scientists wrote in the paper, which was published by Nature Reviews Drug Discovery on Jan. 23.The Moderna and Pfizer COVID-19 shots use modified messenger ribonucleic acid (mRNA) technology. The mRNA is delivered by lipid nanoparticles (LNP).The toxicity risks include “lipid nanoparticle structural components, production methods, route of administration and proteins produced from complexed mRNAs,” the authors of the paper said.Authors of the paper include Eric Jacquinet...
