Differbetween
The complete form, Freund's Complete Adjuvant (FCA or CFA) is composed of inactivated and dried mycobacteria (usually M. tuberculosis), whereas the incomplete form (FIA or IFA) lacks the mycobacterial components (hence just the water in oil emulsion). It is named after Jules T. Freund.

What is Freund's Incomplete Adjuvant?
Listen to pronunciation. (in-kum-PLEET froyndz A-juh-vunt) A mixture of oil and water that is combined with a specific antigen to boost the immune response to that antigen. It is being studied in immunotherapy and as a way to increase the immune response to cancer vaccines.
What is the difference between CFA and IFA?
An essential component of CFA-mediated response is an intense inflammatory reaction at the site of antigen deposition. For most applications, CFA is usually only necessary for the initial immunization, while IFA is the adjuvant of choice for subsequent immunizations. CFA is for research use only, not for use in humans.
Why is complete Freund's adjuvant not administered in humans?
Freund's complete adjuvant is effective in stimulating cell-mediated immunity and leads to potentiation of T helper cells that leads to the production of certain immunoglobulins and effector T cells. Its use in humans is forbidden by regulatory authorities, due to its toxicity.
What is complete Freund's adjuvant?
Complete Freund's Adjuvant, or CFA, is a water in oil emulsion, which also contains inactivated mycobacteria (Mycobacterium tuberculosis is most frequently used). Incomplete Freund's Adjuvant, or IFA, is the same water in oil emulsion, but does not contain the mycobacteria pathogen.
What's an adjuvant?
An adjuvant is an ingredient used in some vaccines that helps create a stronger immune response in people receiving the vaccine. In other words, adjuvants help vaccines work better.
What is adjuvant induced arthritis?
Adjuvant-induced arthritis is a model of chronic immune-mediated joint inflammation that is induced by injection, usually sub– or intradermally, of a suspension of heat killed Mycobacterium tuberculosis ( Mycobacterium Species) in oil ( Freund's complete adjuvant or FCA).
