Vaccine of mixed multi-purpose meningitis strains

摘要

It refers to a multifunctional meningitis compound composed of two vesicles produced by meningitis strain: (a) a vesicle with heterogeneous bacterial activity, which is deficient in outer immune membrane protein compared with the vesicles produced by wild h44 / 76 strain; (b) a vesicle with the same biological activity, which has no defect in its protein compared with the field strain mentioned above. This ingredient is useful in the treatment of Neisseria disease, preferably meningitis.
