I just heard about this and I googled it. The last one I had was in 2007.
This to hard to understand for me.
"Routine adult immunization — In the United States, a diphtheria-tetanus toxoid (DT and Td) or diphtheria toxoid-tetanus toxoid-acellular pertussis vaccine (DTaP and Tdap; Adacel or Boostrix) vaccine 0.5 mL intramuscularly (IM) is recommended every 10 years for all adults with complete prior immunization against tetanus and diphtheria [2,4,5]. At least one of those doses should be with Tdap in adults aged 19 years and older who had not received Tdap previously. When indicated, Tdap should be administered regardless of the interval since the last dose of Td. Subsequently, booster doses with either Td or Tdap can be resumed 10 years later.
Adults who have not been previously vaccinated against tetanus and diphtheria should receive a series of three vaccines (at least one Tdap; the other two can be either Td or Tdap vaccines) [2]. The preferred schedule is a Tdap vaccine dose followed by a Td or Tdap vaccine dose four weeks later and another Td or Tdap vaccine dose 6 to 12 months later.
The following figures summarize the Advisory Committee on Immunization Practices (ACIP) recommendations for immunization of adults without and with comorbidities, respectively (figure 2 and figure 3) [4]. Previously, ACIP only recommended a single Tdap dose, with the rest of tetanus and diphtheria vaccination to be completed with Td; in 2020, it recommended that either Tdap or Td could be used for additional catch-up or booster doses following the Tdap dose since Tdap has a reassuring safety profile and allows providers more flexibility in choice of vaccine. The use of Tdap for prevention of pertussis is discussed in detail separately. (See "Pertussis infection in adolescents and adults: Treatment and prevention", section on 'Vaccination'.)
The rationale for universal vaccination against tetanus and diphtheria every 10 years is waning immunity. In a serologic survey in the United States between 1988 and 1994, fully protective levels of anti-tetanus and anti-diphtheria antibodies were detected in 91 percent of individuals aged 6 to 11 years but in only 47 percent of individuals 20 years or older [1]. Not surprisingly, protective antibody levels were more likely in adults with a history of military service, higher levels of education, higher incomes, and medical insurance [6,7]."
