New Formulation Could Help RNA Vaccines Withstand Higher Temperatures

William Faulkner 2 months ago 4 min read Researchers at MIT have developed a new formulation that could make RNA vaccines significantly more resistant to heat, potentially reducing their dependence on ultracold storage. The approach uses artificial intelligence to optimize the lipid nanoparticles that protect and deliver messenger RNA, or mRNA, inside the body. The researchers found that the modified vaccines could remain stable at room temperature for up to a year and at nearly 100 degrees Fahrenheit (38 degrees Celsius) for as long as two months. The findings could eventually make RNA vaccines easier to store and distribute, particularly in regions where reliable cold-storage infrastructure is limited. AI Helps Improve RNA Vaccine Stability RNA vaccines gained widespread attention during the COVID-19 pandemic and are now being developed for a range of other applications, including vaccines and treatments targeting cancer and infectious diseases.
