You're absolutely correct; the surface is just being scratched on DC treatments for infectious diseases for example. While most other biotechs and pharmas abandoned DC therapies after early failures NWBiO has stuck to their guns against almost absurd levels of criticism and has, in my opinion, become the leading DC based biotech in the world.
It's so easy to dismiss small companies who try to stear clear of the normal Wall Street crap of kowtowing to Hedge Funds. NWBO may have made some missteps that would draw attention, but that doesn't make them dumb or wrong. Swimming against a tide is sometimes awkward and ugly, but their fortitude tells me they know what they're doing.
