Its all. Not just this one. As long as you get non-life threatening adjuvants in your bloodstream as a healthy adult, you will not die, but become weaker. Until you "win" the russian roulette and get the "prize" batch to either finish you or make you sick, having to take drugs made by the same people who make the poison who injured you.

Let Jesus Christ be your protection. You cannot fully mimick disease contagion for the purpose of protection. Even if you could, it would always backfire the more you spread it because diseases arent made to be contained, but fought. At worst, those who deny vaccination have let their Creator fight their diseases instead of relying on cruel, greedy men and their golem companies. This alone is proof that as backwards and nonsensical faith may be sometimes, it may prove the midwit curse.
