1 The whooping cough booster is a combination vaccine with tetanus and diphtheria. 2  The vaccine is called Tdap. 3  Once an adult gets the Tdap vaccine, he or she should get the Td (tetanus and diphtheria) booster every 10 years from then on.
This is the first booster shot for tetanus and one dose is given to all preteens at age 11 or 12. All teens and adults who never got the Tdap shot need one dose in place of a Td (tetanus and diphtheria) shot. Tdap helps protect against whooping cough (pertussis).
