>>"And the fact that the treatment can be considered only a temporary cure, because after treatment, it is possible to be re-infected with the virus,"
In nearly all viral infections, the virus compromises the immune system in some way, whether it is by overwhelming the system with viral matter (Ebola) or hijacking key elements for its own use (HIV). Seymour has already talked about how following infection and nanoviricide treatment, it appears that immune systems are educated against the virus and can more rapidly respond to new infections or reinfections.
Second, there are no approved treatments for viral infections, other than neuraminidase inhibitors, which also does not include the immune system; those instead inhibit either entry or exit of viral matter infecting host cells. The only things are vaccines, which actions are prophylactic and have no effect after infection. Vaccines are not treatments.
