Why is the Cold Sore Herpes Virus impossible to completely eradicate from the body and why is it invincible during dormancy?

Because it literally hides in the body, in our nerves cells.
When the herpes virus enters a cell, the cell tries to protect itself by wrapping the viral DNA tightly around spool-like proteins called histones and condensing it into chromatin, which causes the virus to go dormant. But if the cells are unsuccessful, the chromatin is only loosely bundled, leaving the viral DNA accessible. The virus particles can then turn on their genes and replicate using the cell’s machinery to start a lytic infection, causing disease.

It's a two fold question and until we solve the way it manages to deal with the way it turns its genes off and on ad hoc, it's unclear if we will be able to solve it.
