Is tdap a tetanus shot? i got a tdap shot 5years ago,and previous boosters before that (i'm 22) i cut myself with a rusty nail 3days ago.am i covered?

You're Covered, Dude: Tdap 5yrs ago is fine and should last 10 unless you get a so-called tetanus-prone wound (crush injury, contaminated injury, puncture wound, etc), then at 5 years is the time to get the booster. A rusty nail isn't too much to worry about. It's what might be on that nail that could cause tetanus (spores from the soil) or infection (bacteria from soil or your shoe if it penetrated into your foot).

Go to your MD: For heavily contaminated wounds, a booster may be given if 5 years have elapsed since your last booster. A puncture wound with a rusty nail counts for this type of injury. Tdap includes a vaccine for Tetanus, Diphtheria, and Pertussis. http://wwwnc.cdc.gov/travel/yellowbook/2016/infectious-diseases-related-to-travel/tetanus http://www.cdc.gov/vaccines/hcp/vis/vis-statements/tdap.html
