Summary

MIT researchers unveil VaxSeer, an AI tool that accurately predicts dominant flu strains and optimizes vaccine design months ahead, outperforming WHO selections in a 10-year study by simulating virus evolution and vaccine responses using deep learning models.

Key Points

  • MIT researchers develop VaxSeer, an AI tool to predict dominant flu strains and identify most protective vaccine candidates months in advance
  • VaxSeer uses deep learning models trained on viral sequences and lab data to simulate virus evolution and vaccine responses
  • In a 10-year study, VaxSeer's recommendations outperformed WHO selections for flu vaccine strains in most seasons
