T-JCCC 203 was an experimental virus developed by the Umbrella Corporation. It was a strain of the t-Virus that specifically targeted cancerous cells, making it an "oncolytic virus".

Research[]

The strain was developed sometime before March 1993, and it entered illegal clinical trials. Operating under the guise of a front, the corporation provided the treatment to a hospital operating in the Arklay Mountains.[1]

The first test subject was a 63-year-old man named Doug Frost, who was administered the virus on March 14th. His cancer cells died through apoptosis, and he developed a voracious appetite. However, a sudden change in his condition led to his death just over three days after administration.

The second test subject, a 34-year-old woman named Dorothy Lester, received an administration on May 20th. She was found to have regained normal blood pressure and pulse, as well as self-respiration and consciousness after only a day. However, on the 23rd, she began experiencing unusual EEG readings alongside her voracious appetite. Despite this, the readings eventually calmed back down.[1]
