Low-level laser therapy (LLLT) is a form of light therapy that triggers biochemical changes within cells. Photons are absorbed by cellular photoreceptors, triggering chemical alterations and potential biochemical benefits to the human body.

A Phase 2 clinical trial of an investigational universal influenza vaccine intended to protect against multiple strains of the virus has begun in the United States. The study is sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and is being conducted at four U.S. sites that are part of the NIAID-funded Vaccine and Treatment Evaluation Units (VTEUs).
