Tdap is a combination vaccine that protects against three potentially life-threatening bacterial diseases: tetanus, diphtheria, and pertussis (whooping cough). Td is a booster vaccine for tetanus and diphtheria. It does not protect against pertussis. Tetanus enters the body through a wound or cut.
In the United States, immunizations begin in infancy with the DTaP series of shots. The DTaP vaccine is a 3-in-1 vaccine that protects against diphtheria, pertussis, and tetanus. Td vaccine or Tdap vaccine is used to maintain immunity in those age 7 and older. Tdap vaccine should be given once, before age 65, as a substitute for Td for those who have not had Tdap.
