MRNA vaccine 1 article

An mRNA vaccine delivers engineered messenger RNA encoding an antigen so host cells transiently produce the antigen and present it to the immune system. Formulations commonly use lipid nanoparticles to protect the RNA and promote cellular uptake, while modified nucleosides and sequence design can influence stability and translation. The entity refers to the vaccine modality as a class, distinct from a specific branded vaccine, from messenger RNA as a general molecule and from lipid nanoparticle delivery as a separate technology.
