The Vaccine (ワクチン Wakuchin ) is a key item in Resident Evil 2.
When obtained, it will take the place of Claire's lockpick in the "personal item" space due to its importance, and thus cannot be placed in an Item Box. It's a vaccine for Sherry to cure the G-virus after being implanted G embryos by Wiliam Birkin.
To get it, the Base Vaccine must be used in the vaccine synthesis machine.
