What Is Lockjaw?
Reviewed: Dr. Gromatzky
6. Risk factors
People most at risk of lockjaw are those that have not received the tetanus vaccination. The risk is increased further for people that live in places where lockjaw is common. Thus, it is wise to get vaccinated if you have not been already, regardless of where in the world you may be.
Infection takes place when spores of the clostridium tetani bacterium are able to penetrate deep into the body. This usually means a wound from an animal bite, unsterile body piercings, injuries from nails and splinters, fractured bones, gunshot wounds, and some surgical procedures. It is recommended to get a booster if you suspect you have been exposed.
