America, our health care workforce training isn’t evolving alongside our needs 

America’s health care workforce training is falling out of step with the nation’s changing needs.

While technology can help extend care, it cannot replace a well-prepared workforce. Read the full commentary to explore why modernizing medical education and training pipelines is essential to sustaining access, quality, and equity in U.S. health care.

AI will accelerate vaccine development and medical breakthroughs 

Artificial intelligence promises to fast-track vaccine and drug research in ways traditional methods can’t match. AI can analyze complex biological data, predict immune responses, and streamline discovery so therapies reach patients faster, all while supporting clinicians rather than replacing them. Read the full commentary to learn how AI-driven innovation could accelerate medical breakthroughs, transform research pipelines and help address urgent public health needs.
