Paravacc 1.X
this parasite-repelling vaccine was developed by Uukaablian MedCorp. The vaccine is transported in a cylinder of polished metal. One end of the cylinder is placed against a victim's neck, and a stud at the other end injects the vaccine. Paravacc 1.X causes a slightheadache, but other ill effects are encountered if used as directed. Prolonged use (more than three consecutive days) has been found to cause damaging effects on the user's nervous system.
