I read something about there being a parent on [a strain of] Ebola owned, IIRC, by the CDC.
A few days ago, I was chatting w/ a freeper remarking on the carry-on like nothing's wrong attitude held by our governing elite; esp WRT finances.
Conspiracy Theory time:

botched gun-trafficking sting.
Your scenario is interesting.
Eh Z-MAPP is a therapy for an infected victim, not a vaccine.
The ruling attackers would have to be confident of never becoming infected, or in case of infection they (and their forces, presumably) would have to have high confidence of access to antibodies in doses common to manufacturing (thousands of doses), not discovery (a dozen or so individuals).
But your mindset is somehow proper and it’s still not impossible.
Something in your favor is that because this therapy would not be for the general public it would be subject to NONE of the normal licensing, so scale-up, etc, would be hugely facilitated.
