Hi
If injury is minor and TT has been taken in less than 10 yrs duration then usually TT is not recommended and if injury is major and TT has been taken in less than 5 yrs duration then TT is not recommended.
Next Steps
In your case TT is taken recently so it will protect today's incident..so just observe wound as it shouldn't get infected or any active bleeding
Health Tips
next time take care for pricking injury of any infected material
