More Vaccine Recalls?

Just fill the bottles with sugar water it would all be the same:

• Drugmaker MedImmune is recalling nearly 5 million doses of swine flu vaccine because the nasal spray appears to lose strength over time, federal health officials announced Tuesday.

  The vaccine recall is the second this month caused by declining potency and comes as public health officials urge millions of Americans to get vaccinated against swine flu.

So we have British and French owned companies supplying vaccines that necessitate massive recalls partway into flu season? Should this be some sort of national security issue? We're just curious.
