- The National Institutes of Health (NIH) have begun testing an experimental universal flu vaccine.
- A universal vaccine would be more effective and not require yearly shots.
- Scientists hope the vaccine can be delivered nasally, blocking infections and reducing transmission to other people.
“Influenza can be considered a ‘continuously emerging’ infectious disease, and the diverse and rapidly evolving influenza viruses are a significant public health threat,” Dr. Jeffery K. Taubenberger, senior investigator for the NIH, told Medical News Today.
