Vaccines have been reliably and affordably protecting people from diseases worldwide for centuries. Until the COVID-19 pandemic, however, vaccine development was still a long and idiosyncratic process. Traditionally, researchers had to tailor manufacturing processes and facilities for each vaccine candidate, and the scientific knowledge gained from one vaccine was often not directly transferable to another.
But the COVID-19 mRNA vaccines brought a new approach to vaccine development that has far-reaching implications for how researchers make drugs to treat many other diseases.
I am a biochemist, and my lab at UMass Chan Medical School focuses on developing better ways to use mRNA as a drug. Although there are many possibilities for what researchers can use mRNA to treat, some important limitations remain. Better understanding how mRNA-based drugs interact with the immune system and how they are degraded in human cells can help lead to safe, durable and effective treatments for a wide range of diseases.
