Additive to reduce the cost of vaccines.

In pharmacology, an adjuvant is a drug or other substance, or a combination of substances, that is used to increase the efficacy or potency of certain drugs. For example, an adjuvant is a substance that increases or modulates the immune response to a vaccine.[1]

Official narrative

Various adjuvants are commonly used by vaccine manufacturers to "overstimulate" the immune system to increase the response to a vaccine. These make it possible to reduce the cost of vaccines, or to produce more quickly a larger quantity with a vaccine substance which would be available only in limited quantities.[2]

Adjuvants have been used safely in vaccines for decades. Newer adjuvants have been developed to target specific components of the body’s immune response, so that protection against disease is stronger and lasts longer. In all cases, vaccines containing adjuvants are tested for safety and effectiveness in clinical trials before they are licensed for use in the United States, and they are continuously monitored by CDC and FDA once they are approved.[3]
