this is so stupid, does it have to be an entire arm? just exactly how big does the vaccine have to be? does it have to be an entire bone or just some part of it? even if it was an entire bone, you can just take off a knuckle from a finger, it's not that bad
i wish the author would at least clarify and say something like "the vaccine of the bone has to be at least one foot long" or something since they're automatically going for an entire arm bone. how tf are they planning on eating an entire arm bone anyways?
honestly if they just used their brains and got medical equipment and only took off the minimum amount of a body part i'm sure they would all live
