LNP formulations produce strong immune responses, data shows 

Drug Discovery World

The etherna paradigm for cLNP design is ushering in the rapid generation of novel families of delivery systems for not only vaccination but also for in vivo tolerisation for a host of autoimmune diseases.” The post LNP formulations produce strong immune responses, data shows appeared first on Drug Discovery World (DDW).

Team studies immune response, proteins in blood of young adults who develop rare complication after COVID vaccination

Medical Xpress

Myocarditis, a condition in which the heart muscle becomes inflamed, is a rare complication that can occur after mRNA COVID vaccination. It's estimated that roughly 18 cases occur in every 1 million vaccine doses administered, making it so rare that it is challenging to find cases to investigate.
