Context: Vaccination is considered as the most cost effective method for the prevention of human diseases. For this prevention method, we need certain substances to increase or boost the antibody as well as cell-mediated immune response against various bacterial as well as viral pathogens. Until now, alum was considered as the safest adjuvant for human use, licensed by the United States Food and Drug Administration. Due to the poor adjuvanticity of alum, conventional vaccines require multiple recall injections, at different time intervals, to attain or sustain the optimal immune response. The present review discusses about the necessity of adjuvants for vaccines. Results: Despite the development of many potent adjuvant formulations with vaccine antigen during the last 80 - 90 years, aluminum compounds are still the only approved adjuvants used for routine human vaccines. Conclusions: Based on pre-clinical and preliminary clinical observations, it appears that the range of adjuvants accepted for human vaccines will expand in the coming years.
