Can I apply for a patent for the technology of bioengineering to make hepatitis B vaccine?

Yes, you can. The invention belongs to the field of bioengineering, and particularly relates to a novel hepatitis B therapeutic vaccine and a preparation method thereof. The invention takes antibody molecules as carriers and epitopes as the basis, clones the epitopes of structural functional units which are the most critical in stimulating immune response in antigens into antibody molecules, and integrates antigens and antibodies into the same molecule to prepare a novel hepatitis B therapeutic vaccine. The vaccine has strong immunogenicity, can induce hepatitis B-specific immune response, has the potential to treat chronic hepatitis B, and can be patented.
