Could we vaccinate Herpes to forget how to latch on to cells?

[refurb]

Not really.

The current approach is to try and find an antigen on the herpes virus that the virus can't stop the immune system from recognizing.

Or use antivirals to stop the reproduction process, and the virus eventually dies. That's the approach with hepatitis C.

No. If you create a strain of a disease that is less persistent, it would obviously be wiped out almost instantly by basic natural selection.
