A synthetic vaccine, "Ambrosia", manufactured by the company VersaLife, nullifies the effects of the virus but is in critically short supply. Because of its scarcity, Ambrosia is available only to those deemed "vital to the social order", and finds its way primarily to government officials, military personnel, the rich and influential, scientists, and the intellectual elite. With no hope for the common people of the world, riots occur worldwide, and some terrorist organizations have formed with the professed intent of assisting the downtrodden, among them the National Secessionist Forces (NSF) of the U.S. and a French group known as Silhouette.[17]
