Your post makes no sense at all. It implies that there isn't any vaccine available unless "Noah" decides to hoard some.
So, what happens when a kid steps on a rusty nail? Mom takes him in for a tetanus shot -- which would logically be available off the shelf for just such incidents.
The prosecution rests.
You would think so wouldn't you. Not the case. Better take him to the ER and hope they have tetanus available. It is in very short supply.
