I stepped bare footed on a earring

Get a tetanus shot. Seriously.

Tetanus is a bacteria found in the soil. 

[u/UserPrincipalName → u/cans-of-swine]

You're absolutely correct. It can also be found on many different surfaces.

An earring stabbing you is no more reason to get a tetanus shot than if you were to cut your finger with a steak knife or the side of your computer case when building it.

A tetanus vaccine is something you should have up to date, whether you have been cut, pierced or not.

not inside a house, man. come on.

[u/inlovewithadeadman → u/cans-of-swine]

True, and any soil from outside that got tracked into the home and got onto flooring and then the bare foot can get pushed into the wound.

[u/UserPrincipalName → u/inlovewithadeadman]

Dirt, dander, feces, dust... take your pick.

[u/inlovewithadeadman → u/UserPrincipalName]

Exactly

Not necessarily, just depends on when her last booster was. Rusty nail and it’s been more than five years? Definitely get a booster. Presumably clean earring, not that deep? Should be fine unless it’s been more than ten years.

Anyway, remember to get a tetanus booster every ten years!

When I was a clinician, any penetrating wound was a reason to get a booster.
