简要总结
This is a randomized, blinded, peer-controlled study. There will be 2 treatment groups, screened subjects were given study numbers in the order of enrollment and randomly assigned to the test and control groups in a 1:1 ratio. Subjects were required to complete a 1-dose immunization program with 0.5 ml of vaccine in both the test and control groups, afterwards some subjects entered the immune persistence group.

入选标准
- •7~17 years old at the time of screening
- •Volunteers and their legal guardians or delegates have given informed consent, have voluntarily signed an informed consent form, are able and willing to comply with the requirements of the clinical trial protocol, and are able to complete 180 days of study follow-up
- •Willingness to discuss medical history with the investigator or physician and to allow access to all medical records related to this trial
排除标准
- •Fever on the day of vaccination, axillary temperature >37.0°C

- •Positive urine pregnancy test for females of childbearing age, or plan to become pregnant within 30 days after vaccination
- •Current meningitis or history of meningitis
- •Allergy to certain components or excipients of the drugs used in this clinical trial (mainly including: group A meningococcal podoplanoside, group C meningococcal podoplanoside, group Y meningococcal podoplanoside, group W135 meningococcal podoplanoside, sucrose, mannitol, sodium chloride, dipotassium hydrogen phosphate trihydrate, potassium dihydrogen phosphate)
- •History of epilepsy, convulsions or seizures or history or family history of psychiatric disorders
