Will a unrusted guitar string give you tetnace?

No, an unrusted guitar string will not give you tetanus. Tetanus is caused by the bacteria Clostridium tetani, which typically enters the body through deep wounds or punctures. While rusty objects are often associated with tetanus, it's not the rust itself that causes the infection; rather, it's the bacteria that may be present on any object, including clean or unrusted ones, if they puncture the skin. Maintaining good hygiene and ensuring vaccinations are up to date can help prevent tetanus.
