The key difference in tetanus management for severely immunosuppressed patients compared to healthy individuals lies in the consideration of additional interventions, even if they are fully immunized ,,.

For a severely immunosuppressed person who is fully immunized, there is a need to consider additional boosting with tetanus vaccine and/or human tetanus immunoglobulin (HTIG) ,,. This is because they may not be adequately protected against tetanus despite having completed their immunization course ,,.

In contrast, for healthy individuals who have received an adequate priming course of tetanus vaccine (at least 3 doses), they are generally expected to have adequate protection following a tetanus-prone injury and may not require immediate treatment . If more than 5-10 years have passed since their last dose, a booster vaccine is typically recommended for immediate protection . HTIG is usually reserved for healthy individuals with high-risk injuries or those who have not received an adequate priming course ,.
