Vaccine Adjuvants Help Increase Vaccine Efficacy

Adjuvants are used in vaccine production to stimulate the immune system and raise an early, long-lasting and efficient immune response to the vaccine. This increases efficacy and provides a high degree of protection from the disease against which you are vaccinating. 

By using adjuvants you will reach the same level of immune protection using fewer injections than when vaccinating with the non-adjuvanted antigen alone.
