Talimogene laherparepvec is a cancer medicine that affects the actions of the body's immune system, helping the body produce an "antitumor" response. Talimogene laherparepvec is a genetically modified weak form of type 1 herpes simplex virus (the virus that causes common cold sores).

Talimogene laherparepvec is used to treat a type of cancer called melanoma when it is on the skin or in the lymph glands.

Accidental exposure to the virus in talimogene laherparepvec may cause you to develop symptoms of herpes virus infection.
