Tetanus is extremely rare - and cannot be caused by the type of injury you describe.
Type of injury that causes people to be concerned:
Punture wound, often from something outdoors, that does not bleed.
it is more common (but still incredibly rare!) in drug users, diabetics, and the elderly.
There is a battle of two wolves inside us. One is good and the other is evil. The wolf that wins is the one you feed.
Book and herb loving mama to 1 preteen and 2 teens (when did that happen?). We travel, go to school, homeschool, live rurally, eat our veggies, spend too much time...
Nope, that injury would not concern me for tetanus.
My husband had seizures as a child, which we believe were from dpt. The current dtap is supposed to be safer but I still keep hearing from parents whose kids seize after having it.
I agree with the PPs, I would not give tetanus a nanosecond of worry.
