flag MIT's AMG1541 nanoparticle boosts mRNA vaccine effectiveness 100-fold and cuts doses by 99% in mice, with human trials needed.

flag A new MIT-developed lipid nanoparticle, AMG1541, significantly boosts mRNA vaccine effectiveness while cutting doses by 99%, according to mouse studies. flag The particle’s cyclic ionizable lipid with ester groups improves delivery efficiency and biodegradability, enabling faster clearance and reduced side effects. flag It enhances endosomal escape, allowing more mRNA to reach cells. flag The technology, published in Nature Nanotechnology, could lower costs and improve accessibility for flu, COVID-19, and other mRNA vaccines, though human trials are pending.
