Relevant Terms

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)

  • Emulsifier: a substance that helps to keep the ingredients mixed together

  • Toxoid: an inactive version of a toxin produced by a bacterium. The body is able to make antitoxin without being exposed to the actual toxin. Toxoids are not toxic.
