Tetanus is a serious disease that can be prevented by getting the tetanus shot. There are several different types of vaccines that protect against tetanus, and they are often combined with components that protect us against other diseases as well. This helps reduce the number of shots an individual needs in a single visit. These vaccines include diphtheria, tetanus and pertussis (DTaP); tetanus, diphtheria and pertussis (Tdap); and tetanus and diphtheria (Td) vaccines
