Scientists from the University of Massachusetts Lowell (UMass Lowell), US, are developing a method to freeze dry messenger RNA (mRNA) COVID-19 vaccines so they can be transported and stored at room temperature.
If successful, the lyophilisation (freeze drying) process would eliminate the need for mRNA vaccines manufactured by Moderna and Pfizer-BioNTech to be stored and transported at very cold temperatures, easing supply chain issues and enabling delivery of vaccines to more people worldwide.
