‘Universal’ Nasal-Spray Vaccine Shows Broad Protection in Mice Against Viruses, Bacteria and Allergens
A groundbreaking early-stage study suggests that a single nasal-spray vaccine could one day protect against multiple respiratory viruses, harmful bacteria, and even common allergens. In laboratory tests on mice, researchers found that an experimental vaccine triggered broad immune protection raising hopes for what scientists describe as a potential “universal” respiratory vaccine. However, experts caution that
