Researchers developing, testing nanovaccine to protect against the flu virus

AMES, Iowa – For many of us, a flu shot is a fall routine. Roll up a sleeve, take a needle to the upper arm and hope this year’s vaccine matches whichever viruses circulate through the winter.

The most common method to make that vaccine is now more than 70 years old. It requires growing viruses in special, pathogen-free chicken eggs. It’s not a quick and easy manufacturing process. And, at best, it provides incomplete protection.

Researchers from Iowa State University, the University of Iowa and the University of Wisconsin-Madison – all of them affiliated with Iowa State’s Nanovaccine Institute – are  working together to develop and test what they think could be a better way to fight the flu.
