Tetanus, also known as lockjaw, is a serious but preventable disease that affects the body's muscles and nerves. It causes a person’s neck and jaw muscles to lock, making it hard to open the mouth or swallow. Getting vaccinated can prevent tetanus.
All children should get the first series of tetanus shots starting at age of 2 months.
All children should get the next tetanus shot at age 11 to 12 years.
All adults should get a tetanus shot every 10 years.
