I have m tetanus shot in june 2006 i want to know how long it is good for i mean how many years its work?

10 years: Tetanus shots last at least 10 years the newer shot called tdap (diphtheria tetanus and pertussis)became available for adults in 2005-2006 it protects against pertussis (whooping cough) it should be given once to any one who wishes protection against pertussis and replaces the old dt for most patients. Questions need to be addressed to md or knowledgeable rn.

10 years: A tetanus shot should be renewed every ten years. However, in case of a major injury, a new one should be given if it has been more than 5 years since the last one.
