A Study of An Adjuvanted Inactivated H7N9 Influenza Vaccine
Immunogenicity and Safety of an Alum-adjuvanted Inactivated H7N9 Influenza Vaccine: a Randomized, Blind, Placebo-controlled, a Phase II Clinical Trial
The aim of this study is to investigate the immunogenicity and safety of the inactivated whole-virion vaccine for teenagers and adults.
The investigators will test the vaccine in participants aged above 12 years, for a randomized, blind, placebo-controlled, clinical study. The investigators designed one dosage groups: 15 μg of hemagglutinin antigen. Control group is designed to inoculate seasonal influence vaccine and aluminum hydroxide adjuvant. Participants will receive 2 doses of vaccine at 21-day intervals. Safety up to 6 months and changes in hemagglutinin inhibition (HI) titers at 21 days after each vaccination will be determined.

Intervention / Treatment |
---|---|
Experimental: 15μg H7N9 Vaccine
Participants will be inoculated with 2 doses of 15μg hemagglutinin antigen of H7N9 vaccine at 21-day intervals.
|
The vaccine was a inactivated, whole virion preparation of the influenza A/Shanghai/2/2013(H7N9) virus, propagated in embryonated chicken eggs,mixed with aluminum hydroxide adjuvant.
|
Placebo Comparator: Aluminum hydroxide adjuvant
Participants will be first inoculated with one dose of seasonal influenza vaccine and followed with one dose of aluminum hydroxide adjuvant at 21-day intervals.
|
The seasonal influenza vaccine was a inactivated, split virion preparation of the influenza virus, propagated in embryonated chicken eggs.
The aluminum hydroxide adjuvant was 0.5ml aluminum hydroxide adjuvant.
