sodium chloride + tetanus toxoid

This is a combination of sodium chloride and tetanus toxoid. Tetanus toxoid is an inactivated (detoxified) form of the toxin produced by *Clostridium tetani*, used as an active immunizing agent to prevent tetanus. Sodium chloride serves as an isotonic diluent or stabilizer in the vaccine formulation, ensuring proper osmolarity for injection. The mechanism of action involves stimulating the immune system to produce antibodies against the tetanus toxin, thereby conferring immunity. This combination does not represent a unique branded product but describes a typical formulation found in monovalent or multivalent vaccines where sodium chloride is included as part of the excipient profile[5][7]. Tetanus toxoid vaccines are widely used for prophylaxis against tetanus, especially following injury or as part of routine immunization schedules.
