Problems solved by technology

However, the clinical application of hepatitis B vaccine has not been standardized for many years, and the treatment dose and course of treatment are not uniform. Generally speaking, the dose is too small and the course of treatment is too short, which has not achieved the effect of promoting or restoring immune regulation.

Abstract

The hepatitis B treating vaccine preparation includes recombinant hepatitis B vaccine 40-80 microgram / ml and aluminum 0.5 mg / ml. The preparation process, use and composition of the hepatitis B treating vaccine are also disclosed. The preparation can induce cell immune response for body to eliminate HBV, increase the cell immunity of Balb / c mouse, promote the high level expression of Th1 cell factor, raise T proliferation level and raise specific CTL activity.

Description

technical field [0001] The invention relates to a therapeutic hepatitis B vaccine preparation, preparation method and application thereof, specifically refers to a hepatitis B surface antigen preparation fermented by yeast using gene recombination technology, and belongs to the field of biological products. Background technique [0002] Chronic hepatitis B (CHB) is a common and frequently-occurring disease in my country, and the exploration of its treatment methods mainly starts from the following aspects: anti-virus, regulation of immune function, liver protection (promoting liver cell regeneration), anti-hepatic fibrosis , to prevent cancer, etc., but antiviral treatment is the key to overcome this disease, which has formed a consensus. Currently recognized anti-HBV drugs at home and abroad are interferon-α (IFN-α) and lamivudine. The antiviral mechanism of IFN-α includes immune regulation and direct antiviral effect, while lamivudine inhibits the activity of reverse trans...
