Aluminum compounds are used as immunologic adjuvants to increase the effectiveness of many vaccines. Conventional vaccines require the addition of adjuvants. Aluminium salts are the most commonly-used adjuvants in human vaccines. Examples of depot type adjuvants are oil emulsions. There are many commercially available immunologic adjuvants. Vaccines typically contain one or more adjuvants, used to boost the immune response. Lentinan, PSK, and PSP, are registered anticancer immunologic adjuvants. Glyphosate-based formulations may contain a number of adjuvants, the identities of which may be proprietary. Several different adjuvants have been used in vaccine preparation. I pro-inflammatory response they elicit and their successful use as vaccine adjuvants. There are many known adjuvants in widespread use, including aluminium salts, oils and virosomes. Its unknown how such salts function as adjuvants. These cells (with optional adjuvants) are infused and provoke an immune response. In the 1950s, Parke-Davis employed Jonas Salk as a consultant on vaccine adjuvants. Research on new adjuvants focuses on substances which have minimal toxicity while retaining maximum immunostimulation.
