The $500 million grant for a broadly protective flu shot has confounded vaccine and pandemic preparedness experts.

Experts say the project was in early stages, relied on old technology, and was just one of more than 200 such efforts.

The vaccine is being developed at the National Institute for Allergy and Infectious Diseases by Jeffery Taubenberger and Matthew Memoli .

NIH involvement through more stages of development could give the government greater influence on vaccine's eventual price.

Vaccine is made by inactivating influenza viruses with a carcinogenic chemical called beta-propiolactone.

Scientists are testing the vaccine as a regular shot and as an intranasal spray with the idea of stopping virus in respiratory tract before it causes a broad infection.
