Yeah... Here's the thing... SOMEONE had to produce all of that vaccine. Uncle Dunkie didn't make every drop himself. Which means a corp had to make it, or a secret lab somewhere. And secret labs still use computers. The formula has to be on a chip somewhere. Even if Dunkie spoke the magic formula out loud, someone would be there to write it down. Chemicals like that are complex. I would suspect that somewhere out there is a computer model of the molecular structure, the base components, and some sort of lab testing results. Dunkie wouldn't release all of that unless he was sure it would work.
Basically, it comes down to this. Humanis destroyed the shipment? *blink* Ok, well, let's make some more. And guard it better, this time.
