What ingredient does Freund's Complete Adjuvant contain that is responsible for undesirable side effects?

• A. Attenuated Viruses
• B. Teratogens
• C. Killed Mycobacteria Organisms
• D. Radionucleotides

Answer: (C)

Freund's Complete Adjuvant is designed to boost the immune response by providing strong immune stimuli. The ingredient responsible for the more intense, but undesirable, side effects is the killed mycobacteria organisms included in the formulation. These mycobacterial components provoke a robust inflammatory reaction, leading to pronounced swelling, granuloma formation at the injection site, and sometimes systemic effects like fever or malaise. The other options don’t fit because attenuated viruses are used in vaccines to mimic infection, teratogens would cause developmental harm, and radionucleotides are radioactive materials not used in adjuvants.
