The strain, called T-Vec, was used to treat patients with melanoma as part of one of the final phases of testing of a new drug. The research, published in the _Journal of Clinical Oncology_, is the latest to show how viruses may be used clinically to kill cancer cells. Unlike chemotherapy, which casts a wide net and kills any proliferating cells, viruses often narrowly target cancer cells, which could make them more effective in fighting the disease. The method also appeals to researchers because it activates the immune system to fight cancer. Researchers looked at more than 400 patients with aggressive malignant melanoma, the deadliest type of skin cancer. More than 16% of patients given the T-Vec treatment showed a lasting response for six months, compared with 2% of members of the control group given normal treatment. “We may normally think of viruses as the enemies of mankind, but it’s their very ability to specifically infect and kill human cells that can make them such promising cancer treatments,” said professor Paul Workman, chief executive of the Institute of Cancer Research, in a statement. The drug, produced by Amgen, now awaits approval from the U.S. Food and Drug Administration before it will be offered to patients. ### See the Human Body Under a Microscope  Adrenaline crystals (polarized light micrographs) Reprinted with permission from Science is Beautiful © 2014 by Batsford, an imprint of Pavilion Books Company Limited  Balancing stone from inner ear (colored scanning electron micrograph) Reprinted with permission from Science is Beautiful © 2014 by Batsford, an imprint of Pavilion Books Company Limited  Blood clot (colored scanning electron micrograph) Reprinted with permission from Science is Beautiful © 2014 by Batsford, an imprint of Pavilion Books Company Limited  Breast cancer (light micrograph) Reprinted with permission from Science is Beautiful © 2014 by Batsford, an imprint of Pavilion Books Company Limited  Insulin crystals (polarized light micrograph) Reprinted with permission from Science is Beautiful © 2014 by Batsford, an imprint of Pavilion Books Company Limited  Melatonin crystals (polarized light micrograph) Reprinted with permission from Science is Beautiful © 2014 by Batsford, an imprint of Pavilion Books Company Limited  Penicillium fungus (colored scanning electron micrograph) Reprinted with permission from Science is Beautiful © 2014 by Batsford, an imprint of Pavilion Books Company Limited  Serotonin crystals (polarized light micrograph) Reprinted with permission from Science is Beautiful © 2014 by Batsford, an imprint of Pavilion Books Company Limited  Vaginal cancer cells (colored scanning electron micrograph) Reprinted with permission from Science is Beautiful © 2014 by Batsford, an imprint of Pavilion Books Company Limited  Ventolin crystals (colred scanning electron micrographs) Reprinted with permission from Science is Beautiful © 2014 by Batsford, an imprint of Pavilion Books Company Limited ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3897542/herpes-skin-cancer-melanoma/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3897542/herpes-skin-cancer-melanoma/"},"headline":"How Herpes Is Being Used to Fight Cancer","datePublished":"2015-05-27T12:01:01.000Z","dateModified":"2026-05-11T05:03:19.884Z","description":"Patients whose cells were treated with this STD were 8 times more likely to survive than a control group","url":"https://time.com/3897542/herpes-skin-cancer-melanoma/","keywords":["Cancer"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt3a5f55e5f60d63e9/698851c2a988caf30b6b2bcc/herpes.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Justin Worland","jobTitle":"Senior Correspondent","url":"https://time.com/author/justin-worland/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt3a5f55e5f60d63e9/698851c2a988caf30b6b2bcc/herpes.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Herpes","caption":"Herpes virus","creditText":"Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/cancer/","name":"Cancer"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3897542/herpes-skin-cancer-melanoma/","name":"How Herpes Is Being Used to Fight Cancer"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"TIME Explains: Cancer Screenings","description":"TIME's Alice Park explains how new cancer screening recommendations effect you","thumbnailUrl":"https://cdn.jwplayer.com/v2/media/pAMu9cRG/poster.jpg?width=720","uploadDate":"2012-10-01T11:28:53.000Z","contentUrl":"https://cdn.jwplayer.com/manifests/pAMu9cRG.m3u8","embedUrl":"https://time.com/3897542/herpes-skin-cancer-melanoma/","duration":"PT1M51S","potentialAction":{"@type":"SeekToAction","target":"https://time.com/3897542/herpes-skin-cancer-melanoma/?jw_start={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"}}] ```
