The invention discloses a lipid cochleate carrier based on aluminum ions. ACO is mainly used as a vaccine carrier and has the strong adjuvant function, so that a vaccine adjuvant/transfer system is formed, and immunity induction potency is improved. Being used as the vaccine carrier, the lipid cochleate carrier has the obvious advantages, the ACO carrier is wide in application range, applicable to carrying different vaccines such as subunit vaccine antigen, inactivated/attenuated vaccines and DNA vaccines, ACO stability is high, meanwhile, vaccine interior and exterior stability can be improved by packaging the vaccine, safety is high, materials adopted for ACO have good biocompatibility, dosage amount is large, multiple dosage ways are provided, dosage can be achieved through sinus tract mucosa comprising oral administration and inoculation and can also be achieved through subcutaneous, intracutaneous and muscle injection, immune induction validity is strong, and ACO has the adjuvant function, and can increase cell uptake and improve immune induction validity when carrying vaccines.
