  • Publication number: 20140112954
    Abstract: The present invention discloses a method for preparing HBV Vaccine comprising aluminum adjuvant, which belongs to biological technology field. The method, which is characterized in that aluminum adjuvant Al(OH)3 is produced by an on-line reaction, comprises mixing PBS buffer solution and potassium aluminum sulfate (KAl(SO4)2) solution with hepatitis B surface antigen stock solution, adding sodium hydroxide (NaOH) solution into the mixed solution, so that the adjuvant is continuously produced and hepatitis B surface antigens are continuously coated and absorbed simultaneously. The process is called “in-situ adsorption”.

  • Publication number: 20140112951
    Abstract: Disclosed and claimed is a method of non-invasive immunization in an animal and/or a method of inducing a systemic immune response or systemic therapeutic response to a gene product. The skin of the animal is contacted with a non-replicative vector chosen from the group of bacterium, virus, and fungus, wherein the vector comprises and expresses a nucleic acid molecule encoding the gene product, in an amount effective to induce the response.
