Oral Inoculant Formula "YpcV" is the vaccine to cure Blue Rot. Consuming the yellow liquid cures the player of Blue Rot (in any stage), and gives permanent immunity to the disease. It appears in two container sizes (a single-dose plastic vial, and a much larger sealed drum), and becomes available following certain mid-game events. Details are in the spoiler below.
The drum can be found in the sled with strap carried by King Elias (or Queen Liza) following the Saginaw encounter. Elias/Liza will immediately head southeast to Clearbone Valley and will emerge with the sled (and contents) in tow. The NPC will then walk towards the DMC Gate after leaving Clearbone, and will typically die of a combination of exhaustion, hunger, and dehydration as they near the sprawl. This typically happens 1 tile west and 13 tiles north of the DMC Gate. Medic skill is needed to properly identify the drum and realize its full value. It can be sold at an even bigger price to Hatter, by going to his office when he's available, and showing him the drum, plastic vial and the glass vial of YPC, and then using the Medic skill. When asked if you can leave the drum with Hatter, accept and after a week, the player must return to Hatter's Office, where he will pay the player $200,000.
Alternatively the cure is given by King Elias after the Saginaw encounter after choosing the right answers. The player has to give his real name, tell the king the church is doomed and then state that the flood is a lie. The king will then hand the cure to the player along with his belongings and pages from the Blue Frog book. The king will also state that the item is a cure to the Blue Rot.
