      | Vaccine Adjuvant Name | TF-Al | 
        
      | Adjuvant VO ID | VO_0005751 | 
        
      | Description | TF-Al is a combined adjuvant made by mixing TFPR1 (a novel immune modulator activating TLR2) with Aluminum hydroxide (Alum). It enhances both Th1- and Th2-type immune responses and is designed to improve vaccine efficacy in genetically diverse subjects. | 
        
      | Stage of Development | Research | 
        
      | Host Species for Testing | Mouse | 
        
      | Components | TFPR1 is a novel adjuvant for protein and peptide antigens,formulating TFPR1 and alum at a certain ratio and compared its adjuvanticity with that of TFPR1 and alum | 
        
      | Structure | Physical mixture of TFPR1 protein + Alhydrogel® alum Final volume ratio: 1 (alum): 4 (TFPR1): 5 (antigen) | 
        
      | Preparation | Mix 1 part alum with 4 parts TFPR1 (250 µg/mL) Combine with equal volume of antigen solution Final dose contains 10 µg TFPR1 in 100 µL | 
        
      | Dosage | OVA: 10 µg per mouse (3 injections, 3-week intervals) HBsAg: 1 µg per mouse (2 injections, 3-week interval) | 
        
      | Function | we first compared the adjuvanticity of TFPR1 in two commonly used inbred mouse strains, BALB/c and C57BL/6 mice, in vitro and in vivo, and demonstrated that TFPR1 activated TLR2 to exert its immune activity in vivo | 
        
      | Safety | No adverse effects reported in mice |
