Shabby, you just don't understand that the person is the expert on all things to do with diagnostics and vaccines and that whatever they say about NanoLogix has to be true because they said it. Please try to respect their opinion. You mentioning the reality of the TB scenario and vaccinations doesn't help their argument, because we MUST ignore the FACT that one-third of the world's population is infected with some form of TB even though a vaccine has been in use for almost a century and there should be no way there can be an argument in support of TB diagnostics since there's a vaccine that exists.
