vaccine

hey im on disc 4 trying to do all the remaining sidequests and as i was training to fight ozma i ran out of vaccines and amarant has virus, no other item or skill will get rid of it, does anyone know where i can buy vaccine? or will amarant have virus till i get some from an enemy?

Go to Daguerreo, a town in the south-western islands on the world map. You can buy Vaccines there. That's one place for Vaccines for sure. I'm sure there are other places too, but I can't remember which of them are accessible on Disc 4.
