One-liner

Tetanus prophylaxis is governed by four rules for the active booster (Tdap/Td) and a simple dichotomy for passive immunity (TIG): TIG is only needed for dirty wounds in high-risk patients.

High-yield summary

• Vaccine Types: DTaP (Diphtheria, Tetanus, acellular Pertussis) for children; Tdap for adolescents/adults; Td for adults.
• Decision Separation: Always separate the decision of when to give the vaccine (active immunity) from when to give the immune globulin (passive immunity).
• Vaccine Rules (Completed Series):
• Clean Wound: Booster needed only if > 10 years since last shot.
• Dirty Wound: Booster needed only if > 5 years since last shot.
• TIG Administration: Tetanus Immune Globulin (TIG) is never given for clean wounds but is given for dirty wounds in patients with either an unknown/incomplete vaccine history or immunocompromised status.
• Special Considerations: Boosters are generally recommended every 10 years; vaccination is mandatory during pregnancy (Weeks 27–36) and for close contacts of newborns.

Learning objectives

• Differentiate between active immunization (vaccine booster) and passive immunity (Tetanus Immune Globulin/TIG).
• Apply specific time intervals for tetanus boosters based on wound contamination level (clean vs. dirty).
• Identify high-risk populations requiring TIG administration, including immunocompromised patients and those with unknown vaccine history.
• Recognize the appropriate timing of vaccination during pregnancy and for close contacts of newborns.
