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.
After getting the Tdap vaccine as a preteen or teen, adults need to get a Td (tetanus and diphtheria) booster shot every 10 years to stay protected. For adults who didn't get Tdap as a preteen or teen, the easiest thing to do is to get Tdap instead of their next regular Td booster.
