Ganciclovir
Ganciclovir has also been used with some success in treating "Human herpesvirus 6" infections.
Herpes simplex research
A study from the Albert Einstein College of Medicine, where glycoprotein D (gD-2) was deleted from the herpes cell, showed positive results when tested in mice. Researchers deleted gD-2 from the herpes virus, which is responsible for herpes microbes entering in and out of cells. The vaccine is still in early stages of development and more research needs to be conducted before receiving FDA approval for clinical trials.
