Wonder if they could design a harmless virus to pre-infect T-cells which do no harm to the cell but effectively block the HIV from infecting?

A virus with a limited life span, capabilities and countermeasures known once the job is done or the virus is no longer needed.


"Onboard the nanoshuttle itself is a special type of virus called a bacteriophage, or phage for short, that infects only bacteria."
