Tetanus toxoid, diphtheria toxoid, detoxified pertussis toxin, filamentous hemagglutinin (a cell surface protein), pertactin (outer membrane protein), and fimbriae types 2 and 3 (parts of the bacterium that allow it to attach to host cells)

Inactive ingredients:
Amounts are based on a 0.5 mL dose

Adjuvants: strengthen the immune response to the vaccine

Antibiotics: used to prevent contamination during manufacturing


Relevant Terms:

  • Antibiotics: substances that kill bacteria or prevent them from dividing. Antibiotics are used in some vaccines to prevent contamination during the manufacturing process

  • Antibody: a protein made by the immune system in response to a foreign particle (antigen). These proteins circulate in the blood and help defend the body against the substance

  • Antigen: This is any substance that triggers the immune system to create antibodies. For example, allergens such as pollen are antigens

  • Antitoxin: an antibody that neutralizes toxins

  • Bacterium: The singular of bacteria (one bacterium, two bacteria)
