The Colorado health department said Friday it wants to target the remaining supplies of the flu vaccine to those most in need, including young children between six and 23 months old, people over 65, and people of all ages with chronic health conditions.
Doctor Ned Calonge, the state's chief medical officer, says healthy people between five and 49 years old could get the new nasal flu vaccine spray. It is in higher supply than the injected vaccine.
The two companies in the U.S. responsible for producing all of the nation's flu vaccine, say they are out of stock. Together, Chiron and Aventis Pasteur have produced 80 million doses of the vaccine this year, usually plenty to get through the flu season.
It takes four months to produce the vaccine, making it impossible to make more before the end of the flu season.
