Because when you have a self-spreading vaccine, you also get a self-spreading illness that is more resiliant. The main concern with biological warfare is the chance of the virus mutating and killing your own people, but if you can send out simultaneously a contagious vaccine that only effects, in example, Chinese people, but a virus that only effects non-Chinese people (again, just in example), then you safeguard yourself against biological weapon feedback.
And there's ALWAYS profit in military technology development. The art of killing people different than yourself is always in vogue, and always sells, unfortunately.
There's no profit in a self spreading vaccine though so I'm not sure where this will go.
Sure there is!
