Patient Education

Tetanus, Diphtheria (Td) Vaccine


Why get vaccinated? Tetanus and diphtheria are very serious diseases. They are rare in the United States today, but people who do become infected often have severe complications. Td vaccine is used to protect adolescents and adults from both of these diseases. Both tetanus and diphtheria are infections caused by bacteria. Diphtheria spreads from person to person through coughing or sneezing. Tetanus-causing bacteria enter the body through cuts, scratches, or wounds. TETANUS (Lockjaw) causes painful muscle tightening and stiffness, usually all over the body. It can lead to tightening of muscles in the head and neck so you can't open your mouth, swallow, or sometimes even breathe. Tetanus kills about 1 out of every 10 people who are infected even after receiving the best medical care. DIPHTHERIA can cause a thick coating to form in the back of the throat. It can lead to breathing problems, paralysis, heart failure, and death. Before vaccines, as many as 200,000 cases of diphtheria and hundreds of cases of tetanus were reported in the United States each year. Since vaccination began, reports of cases for both diseases have dropped by about 99%.
