Okay. Am I missing something? They don't want to use expired drugs because....? What?
FWIW, FDA makes drug makers see if their drugs can handle a 2 year shelf life. If they pass that test, it is cleared for market. Most drugs are fine after that date, they just haven't been tested.

So what if they are expired! Maybe the drugs have lost just a tiny bit of their effectiveness. Just give them a tripple dosage! Problem solved.
