MIT Engineers Develop Heat-Stable RNA Vaccine Formulation

Engineers at MIT have created a new formulation that stabilizes lipid nanoparticles for RNA vaccines, allowing them to endure high temperatures. This innovation, published in Nature Biotechnology, could significantly expand global distribution of RNA vaccines, which currently require ultracold storage. The research also demonstrated that this heat-resistant method could be used in solid microneedle patches, eliciting an immune response comparable to traditional injectable vaccines.
