Definitions
- the present invention relates to a novel vaccine configuration. More specifically, the present invention relates to a novel vaccine using double-stranded RNA as adjuno.
- influenza viruses particularly influenza A virus
- influenza A virus have significant antigenic mutations, which produce viruses that are not neutralized by antibodies produced by previous vaccines (ie, previously acquired infections).
- the efficacy of the vaccine often ends in only one season.
- novel strains that differ immunologically due to point mutations (continuous antigenic mutations) in genes encoding surface glycoproteins (hemagglutinin [hemagglutinin; HA] and neuraminidase [NA]) and discontinuous mutations in antigens Often occurs.
- the internal protein is relatively highly conserved in the continuous mutant and the discontinuous mutant.
- Current vaccine immunization only elicits allogeneic humoral immunity, not common immunity based on cell-mediated immunity, and the effect is diminished if the strain is different from the prevalent strain. become.
- the predominant strain of influenza virus even if the strain is not discontinuous or continuous over the next year, the immunization must be performed every year because the antibody titer decreases. There is also. Hemagglutination-inhibiting (HI) and neutralizing antibodies have been reported to persist for months to years and then decline gradually. However, even if no such reduction is seen, annual vaccination is recommended. This is because antibody titers may decrease within the year following vaccination.
- HI Hemagglutination-inhibiting
- neutralizing antibodies have been reported to persist for months to years and then decline gradually. However, even if no such reduction is seen, annual vaccination is recommended. This is because antibody titers may decrease within the year following vaccination.

- Adjuvants are a generic term for substances that, when combined with an antigen, cause an increase in antibody production and an enhanced immune response; in a more preferred embodiment, a non-toxic, modulating or potent adjuvant is used. Adjuvants are required for use with conventional vaccine antigens to elicit a faster, more potent, or prolonged response. Such adjuvants are also useful in cases where antigen supply is limited or production is costly.
- Adjuvants may be used, for example, in mineral, bacterial, plant, synthetic or host products. Classified according to.
- the first class is a mineral adjuvant, for example, an aluminum compound.
- the first use of aluminum compounds as adjuvants was described in 1926. Since that time, antigens precipitated with aluminum compounds or mixed with or adsorbed to preformed aluminum compounds have been used to enhance immune responses in animals and humans.
- Aluminum compounds and similar adjuvants appear to work through the following mechanisms. Aluminum physically binds to the antigen to form particles that slow the rate of absorption of the antigen by the tissue after injection, thus allowing the interaction between the antigen and the cell presenting the antigen, such as macrophages or follicular-dendritic cells. Prolong the time of action. Alternatively, adjuvants further activate such interactions.
- Aluminum particles are demonstrated 7 days after immunization in the local lymph nodes of the egret, and other significant functions may direct antigens to T cell-containing regions in the nodes themselves.
- Adjuvant efficacy has been shown to correlate with regional lymph node activation. Although a number of studies have demonstrated that antigen administered with aluminum activates humoral immunity, cellular immunity appears to be only marginally increased. Aluminum has also been described as activating the complement pathway. This mechanism may play a role in the local inflammatory response as well as in immunoglobulin memory.
- Aluminum compounds are almost the only safe adjuvants currently used in humans. However, vaccines containing aluminum sometimes cause local reactions. Although the development of allergy is usually not a major clinical problem, aluminum compounds also induce eosinophils into the injection area via a T-cell dependent mechanism, elicit an IgE response after antigen priming, and According to this response, it is said that it activates a population of specific cells with helper functions.
- Bacterial adjuvants have recently been purified and synthesized (eg, muranyl dipeptide, lipid A). The host-derived immunoreactive protein is clawed (interleukin 1 and interleukin 2). Recently, Bordetella pertussis, lipopolysaccharide and Freund's complete adjuvant (FCA) are being used at the laboratory level.
