primary or booster immunization in this clinical trial;\n* According to the judgment of the investigator, the subject has any other factors that are not suitable for participating in the clinical trial.\n\nExclusion Criteria:\n\nFor primary immunization stage\n\n* Test-tube baby who is suffering from perianal abscess, severe eczema or pathological jaundice;\n* History of severe allergic reactions requiring medical intervention (such as swelling of mouth and throat, dyspnea, hypotension or shock);\n* A clearly diagnosed history of thrombocytopenia or other coagulation disorders that may cause contraindications to intramuscular injection;\n* History of severe abnormal labor and delivery, asphyxia rescue, congenital malformation, serious developmental disorder, serious genetic defect, serious malnutrition or serious chronic disease;\n* Suffering from serious cardiovascular diseases (pulmonary heart disease, pulmonary edema), serious liver and kidney diseases, and diabetes

of encephalopathy, epilepsy, convulsions or seizures, and other progressive neurological diseases;\n* Suffering from acute illness or in the acute phase of chronic illness, or using antipyretic, analgesic, and antiallergic drugs (such as acetaminophen, ibuprofen, aspirin, etc.) three days before vaccination;\n* Long term treatment with immunosuppressants, such as long-term (continuous for more than 2 weeks) use of glucocorticoids (such as prednisone or inhaled steroids (budesonide, fluticasone) and similar drugs);\n* History of using immunoglobulins and / or any blood products (except hepatitis B immunoglobulin) within 3 months before enrollment;\n* Plan to participate or be participating in any other drug clinical research;\n* Plan to move out of the local area before the end of the study or leave for a long time during the scheduled study visit period;\n* According to the judgment of the investigator, the subject has any other factors that are not suitable for participating in the clinical trial.\n\nFor booster immunization and immune persistence stage\n\n* Has been vaccinated with any meningococcal vaccine after primary immunization and before blood collection of booster immunization;\n* Has been vaccinated with any meningococcal vaccine after booster immunization and before blood collection of immune persistence;\n* Has been known or suspected to have immunological defects since participating in this clinical trial, including being treated with immunosuppressants (such as chemotherapy, corticosteroids, antimetabolics, cytotoxic drugs, etc.) and HIV infection;\n* History of using immunoglobulins and / or any blood products within 3 months before booster immunization;\n* According to the judgment of the investigator, the subject has any other
