Too late for "Jersey Shore", but still

Herpes vaccine.

Scientists are reporting early success with an experimental herpes vaccine that uses a genetically modified version of the virus.

The gene edit prevents the virus from performing its normal evasive maneuver: hiding out in nervous system cells in order to elude the immune system.

I don't have a TV, so I never watched "Jersey Shore".  The couple of times I saw some interview or "news" article about any of the cast members, my only thought is that you could wash out their vaginas with Valtrex five or six times and still have viable cultures living there.
