Nucleoside-modified messenger RNA (mRNA)
mRNA provides real-time instructions to every cell to make the proteins necessary to drive aspects of biology, including in human health and disease. The mRNA molecule in the vaccine is wrapped for protection in oily bubbles made of lipid nanoparticles. The technology does not use inactivated virus, attenuated virus or any other kind of virus, but uses mRNA to provide a blueprint for cells to build the bodys defence against the virus.
