Components |
AddaVax and PolyI:C combined adjuvant (AP adjuvant) |
|
Structure |
Mixture of: AddaVax: oil-in-water emulsion PolyI:C: synthetic double-stranded RNA analog Not a single molecular entity; physical mixture. |
|
Preparation |
Mixed in a 1:1 (v/v) ratio: AddaVax PolyI:C (50 μg per mouse per dose) |
|
Dosage |
Vaccine: H3 antigen at 3–15 μg per mouse Adjuvant: PolyI:C at 50 μg/mouse, mixed with equal volume of AddaVax |
|
Function |
These findings indicate that AP is a potential novel adjuvant and can be used as a safe and effective adjuvant for MDCK-based influenza inactivated vaccine to induce cellular and antibody protective response. |
|
Safety |
Good safety profile |
