Paravacc 1.X was a parasite-repelling vaccine developed by Uukaablian MedCorp on Uukaablis in 8 ABY. The vaccine was contained in a polished metal cylinder, and administered by injection into the back of the neck. A mild headache occurred after injection. Prolonged use of the product (over three days at a time) was known to produce deleterious effects to the nervous system. The government of Uukaablis advertised to other worlds its willingness to trade the vaccine for more advanced technologies.
