A member asked:

Is a 7 year old tetanus shot effective for stepping on a rusty nail?

A doctor has provided 1 answer

Sort of: If it is a true puncture wound with a rusty or dirty nail we generally would like the shot no more then five years. The vaccine loses potency at about 7 to ten years. Talk to your dr. Keep the wound clean.
