Pediatric flu vaccines significantly reduce the number of childhood cases of influenza, new research from Harvard Medical School confirms. The findings, published on June 1 in JAMA Pediatrics, show that for every 100 children vaccinated, between nine and 14 fewer children catch the flu.

New York, NY — [June 1, 2026] —As hospitals and health systems rapidly adopt artificial intelligence (AI) technologies, a new study by investigators at the Icahn School of Medicine at Mount Sinai finds that the policies governing health care AI are expanding quickly but remain fragmented across regulators, governments, and standards organizations. Their findings were published in today’s online issue of npj Digital Medicine [https://doi.org/10.1038/s41746-026-02734-y]. The researchers analyzed 240 health care AI-related policies published between 2016 and 2025 using their newly developed framework called the Health & AI Policy Index. The analysis found that oversight efforts are accelerating worldwide, though no single, unified framework currently exists to guide how AI should be deployed, monitored, and governed in clinical settings.
