Immunostimulants are substances that stimulate the immune system. Specific immunostimulants such as vaccines stimulate an immune response to specific antigenic types. Non-specific immunostimulants do not have antigenic specificity and are widely used in chronic infections, immunodeficiency, autoimmunity and neoplastic diseases.

Drug classes:

• bacterial vaccines
• colony stimulating factors
