FASTER, PLEASE: Nasal Spray Holds Hope in Fighting Flu Epidemic.

Scottish and American scientists have found a new way to prevent flu infections that could, in theory, be used to fight an epidemic long before a vaccine is ready.

The method, successfully tested only in mice thus far, is a nasal spray of engineered proteins that coat the receptors in the nose and throat to which flu viruses attach.

Mice that got the spray as long as a week before being given a lethal dose of viruses from the 2009 pandemic flu were fully protected, according to the team at the University of St. Andrews in Scotland that invented the proteins.

That sounds promising.
