Meningococcal Meningitis Clinical Trial
Official title:
A Single-center, Open Trials to Evaluate the Safety of Freeze-dried Group ACYW135 Meningococcal Conjugate Vaccine
Safety Evaluation of freeze-dried Group ACYW135 Meningococcal conjugate vaccine in healthy people above 2-months-old
There are five different age groups(18~55 years/7~17 years/1~6 years/7~10 months/2
months),each group has 40 people and divided into two subgroups. Each subgroup will inject
different vaccine(MCV4 4μg,MCV4 8μg).For 7~10 months&2 months age groups,there are 2&3
injection seperately. Each injection interval is 1 months.
After 7 days observation of 1 dose immunization in Group 18-55 years old adults, if there
are no serious adverse events associated with vaccines, or severe adverse reactions rate is
less than 10%, 7 to 17 years old and 1 to 6 years old age groups will continue to inoculate
in order. After the first dose of 7~10 months group and evaluating safety, 2 months group
immunized the first dose. All participants completed the immune procedure, then observed the
safety to 30 days after whole immunization.
Data collection: Subjects completed diary card, the researchers collected original data and
fill out the case report form for data entry and statistical analysis.
