A production delay of the FluMist flu vaccine has U.K. pharmaceutical giant AstraZeneca scrambling to alleviate shortages at doctors offices this flu season.
Only 5 million doses of the vaccine made by Gaithersburg-based MedImmune, the biologics research and development arm of AstraZeneca PLC (NYSE: AZN), has been delivered so far this season. AstraZeneca originally said it planned to distribute 15 million doses.
