Moderna

Traditional vaccine development takes 5-10 years. When COVID-19 emerged in January 2020, the world needed a vaccine in months, not years. mRNA design optimization was a key bottleneck.

Moderna used AI/ML models to design optimized mRNA sequences, select lipid nanoparticle formulations, and predict manufacturing outcomes. AI compressed the design-selection cycle from months to days.

Initial mRNA-1273 design finalized in 48 hours of the genetic sequence being shared. Clinical trials started in 66 days. Vaccine authorized in 11 months — fastest in history.
