As you know I know zero about science of all kinds, but it seems to me that given what I think is apparent about the companies: 1. NNVC doesn't need 30 people. Seven sounds like plenty. and 2. TheraCour doesn't need 25 unless they have other customers.
Some of those 30 employees are probably technicians, I doubt that they're all PhDs. In any case, you may have noticed that NNVC is having a hell of a time scaling up. I suspect several PhDs are assigned to solving that problem. Tox requires methods for detecting the breakdown products of nanoviricides in tissues. I suspect more PhDs are working on that. If there was no PhD level work to be done tox would have been completed long ago.
