Pan-Immunity Virion

The Pan-Immunity Virion was a general immunity agent intended as a preventative measure against Chinese use of biological weapons and utilized in agricultural research.

Background
Started in 2073, West Tek's Pan-Immunity Virion Project aimed to combat the effects of biological weapons by altering uninfected DNA so that it was no longer susceptible to standard viral infection. The project was subsequently extended under the Greenhouse Initiative, a project designed to facilitate and control the production of genetically-modified foods to combat global hunger, but later disbanded to focus resources on the research of other mutagens. The Pan-Immunity Virion paved the way to the Forced Evolutionary Virus.

Characteristics
Unforeseen side effects of clinical trials included abnormal growth rate accompanied by increased brain activity.

Appearances
The Pan-Immunity Virion is mentioned only in Fallout and Fallout 76.
