Technology Factsheet: Vaccine Platforms

A vaccine platform is a “plug -and-play” physical framework that can be used when developing vaccines for emerging infectious diseases, such as COVID-19. Vaccine platforms use a base carrier or “vehicle,” such as a nucleic acid, viral vector, or liposome, which can be used interchangeably for various diseases. Once designed and licensed for one vaccine, the development of future vaccines using the same platform would simply require substituting the desired antigenic component, or a genetic compound that normally triggers an immune response. This would enable faster and cheaper development, regulatory approval and mass production.
