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.
1 Tdap should be given as a one-time booster in place of Td. Tdap is especially important for those in close contact with infants.  Adolescents 11 through 18 years old (preferably at age 11-12 years old) and adults 19 years or older should receive a single dose of Tdap.
