Would you get a Tetanus booster because of this?

Fluther Newbie.

I was in my garden yesterday, I had made tin can covers for my seedlings.
They had grown big enough to not be eaten by slugs so I pulled the tin can covers off.
I pricked myself with one of the tin cans – a small pin prick, it was a little rusty, I squeezed it so it bled, a tiny drop of blood came out and then I immediately washed it with hot water and soap.

I feel as though I’m over reacting but I know that Tetanus can get into your body through a rose thorn cut.

What do you guys think?
Thank you for your thoughts.
No smart comments – unless they are aimed at making me feel ridiculous.
