The invention relates to a method of obtaining a vaccine composition comprising at least one antigen and at least one adjuvant.

Development of inactivated vaccines or vaccines containing purified antigens, is becoming an increasingly important problem, as it allows to eliminate the side effects in a patient undergoing treatment. However, improving the quality of the antigens develops to the detriment of their immunogenic nature. For this reason, antigens associated with immune adjuvants.

Immune adjuvants are products that enhance the immune response when they are introduced in the presence of viral antigens, bacterial or synthetic origin. They provoke mass appearance of macrophages at the site of injection, and then in the lymph nodes, increase the production of specific immunoglobulins, antibodies and stimulate numerous cells involved in the mechanisms of immune protection.

These adjuvants are of diverse nature. They may, for example, be an emulsion of the type water-in-oil S/N, or oil-in-water N/E, or water-in-oil-in-water E/N/E, or oil-in-water-in-oil N/E N/.

Very effective adjuvants's adjuvant; they are obtained from a combination of mineral oil and a complex ester of mannitol, whether or not containing killed is micobacteria. Vaccine produced by mixing equal parts of the adjuvant's adjuvant with antigenaemia water environment, remain standards in the world for laboratory research. They are in the form of emulsions, water-in-oil (S/N), i.e. emulsions in which the continuous phase is an oil or mixture of oils, and the dispersed phase is an aqueous phase, which may include solubilizing excipients, such as, for example, glycerol or dimethyl sulfoxide. The active principle is usually localized in the aqueous phase, which is often buffered saline solution. This phase is in the form of drops, separated between an oil film. This part allows you to get stronger and longer lasting in time biological responses.

However, emulsions of this type of E/N are usually highly viscous emulsions, and therefore create difficulties when introducing them by injection. These emulsions are often forced to use a syringe with a large bore needle that is causing pain when injecting and injure the injection.

The mass content of the aqueous phase in the emulsion E/N for intravenous infusion is in the range of 30-40% on 100% of the emulsion. The maximum content can sometimes be up to 50% of the mass. However, this limit is the brake is brilliant moment in particular, for the development of polyvalent vaccines, in which there are multiple antigens and for which it is more preferable to obtain emulsion E/N content of the aqueous phase above 50 wt%.

However, in the emulsion E/N with the low content of the aqueous phase, reaching up to 20 wt. -%, the viscosity of the emulsion is very close to the viscosity of the oil. The increase in the mass fraction of the aqueous phase increases the viscosity. For this reason emulsion with 20% of the mass. water, having a viscosity of 100 MPa·s, measured using a BROOKFIELD viscometer LVT with engine No. 2, rotating at 60 revolutions per minute, turns into a creamy mass, which with great difficulty administered by injection once the water content is increased to 50 wt%.

Some oil adjuvants produced in the sale are in the form of emulsions E/N, such as MONTANIDETMISA 70, which provide injectable emulsion E/N, containing about 30% of the mass. the aqueous phase, 70% of the mass. oil phase and having a viscosity of about 50 to 100 MPa·s, measured using a BROOKFIELD viscometer LVT with engine No. 2, rotating at 60 revolutions per minute. Other adjuvants, such as MONTANIDETMISA 50V2, allow to obtain injectable emulsion E/N, containing about 50 wt%. the aqueous phase, 50 wt%. oil phase and having a viscosity lower than 250 MPa·s, measured using viscos the meter BROOKFIELD LVT, equipped with engine No. 2, rotating at 60 revolutions per minute.

In the international patent application published under number WO 99/20305, disclosed the use of surfactants, including mannitol oleate, mineral oils, such as MARCOLTM52, to obtain emulsions, called liquidwith a viscosity of about 500 MPa·s, measured using a BROOKFIELD viscometer LVT with engine No. 2, rotating at 60 revolutions per minute.

The concept of liquid emulsion depends to a large extent on the scope of its application. As for injectable emulsions, the upper limit of viscosity for liquid emulsions are defined relative to the viscosity of the emulsion type E/N, is used as standard, which contains 50 wt%. the aqueous phase and 50 wt%. incomplete adjuvant's adjuvant (IFA); the viscosity measured using a BROOKFIELD viscometer LVT with engine No. 3, rotating at 30 rpm is about 2000 MPa·C. This emulsion is considered as a very viscous.

Emulsion type E/N will be called liquid, if its viscosity is 4 times smaller than the viscosity of a standard emulsion, i.e. below 500 MPa·s at 25°C. measured using a BROOKFIELD viscometer LVT with engine No. 2, rotating at 30 revolutions per minute.

However, liquid emulsions are generally less stable than more viscous emulsions, because after only a few days after their receipt of the observed phase separation at room temperature.

There are polymers, thickening the aqueous phase and are in the form of powders, such as homopolymers of acrylic acid in the sodium form or copolymers based on acrylic acid and its esters. Can be called, for example, polymers produced by a Noveon under the trademark CARBOPOLTMand PEMULENTM. They are described in particular in U.S. patents US 5373044, US 2798053 and in the European patent EP 0310532. These polymers were originally developed as thickeners designed for thickening compositions intended primarily for cosmetic purposes, and is described and used for several years. These polymers derived from monomer, such as, for example, acrylic, methacrylic acid, esters of acrylic acid or methacrylic acid, dissolved in a medium of an organic solvent. During the polymerization reaction occurring after the addition of various catalysts under specific conditions of temperature and pressure, the polymer becomes insoluble state from the initial environment of the solvent and precipitates on the bottom of the reactor. This method is called "polymerization deposition".

Obtained in such Obratnaya, of which the most famous are the polymers CARBOPOL brand®have proven to be very effective and are widely used in cosmetics. These polymers are also used for various pharmaceutical purposes:

- obtaining the polymer matrix to achieve a delayed release

- obtaining a polymer gel and the formation of complexes of these polymers with proteins,

- receiving polymer films that provide protection during contact with biological media,

- getting bioadhesive compositions, providing the greatest residual deformation when applied to mucous membranes,

- getting adjuvants for vaccines.

The use of polymers as adjuvant for vaccines at the end of the mass content of the polymer order "percent" is in the form of a liquid, transparent and easily injectable vaccine.

Adjuvant properties of synthetic substances are closely related to their physical form introduction. Thus, the size of the particles used to create a significant adjuvant effect, is the main parameter that can control the ability to perform the functions of immunocompetent cells. In addition, depending on the size of the particles also creates the possibility of orienting response to the production of antibodies (humoral immune response) and what and also to stimulate specific cells of the immune system (cellular immune response). Synthesis of microspheres of various polymers in the solvent environment in the form of dispersions are widely described in the literature and creates the possibility of encapsulating biologically active agent (which may be the antigen in the case of vaccines) or serves as an adsorption substrate for transport and presentation of the active agent connected to the external surface of the microspheres by using more or less strong interaction forces.

The regulation of the particle size of the adjuvant always remains an unsolved problem, since it must be solved simultaneously with the stability of the adjuvant particles in time. In particular, it is important to avoid aggregation of particles during storage and separation of phases. The regulation of the particle size must also be accompanied by the stability of the composition after injection of a living being, in particular, in connection with the stresses to which they are exposed because of a change in pH, presence of enzymes and temperature changes.

Therefore, the applicant has set a task to develop an original method of polymer synthesis, allowing you to control the size of the agglomerates of the polymer (or "microgels"), which would allow to achieve a very good adjuvant characteristics. To solve this problem, technology was used polymerization in emulsion water-in-oil S/N or inverse emulsion to obtain this floor is Mer. Thus, the size of the monomer droplets of the solution is controlled by the use of emulsifying surfactant system of the type water-in-oil adapted to the technology of producing emulsions E/N. We are talking mainly about the combination of lipophilic emulsifying surfactants having, for example, the number of products HLB of 2 to 7, with hydrophilic emulsifying surface-active substance with, for example, the number of products HLB of 10 to 15, with the average weightedproviding the achievement of a homogeneous emulsion E/N. Polymerization of the monomers occurs when adding catalysts and other cross-linking agents in the usual concentrations, under conditions of pH and temperature, suitable for complete reaction of the monomer prior to the formation of polymers.

The particle size of the adjuvant has a direct impact on the immunological properties of the compositions which contain them. In addition, depending on the patient, the subject of vaccination, and the type of the vaccine may vary, the optimal particle size. Thanks to special technology of preparation of emulsions (optimization products HLB, the nature of the surfactant concentration, method of production) became possible in the process of polymerization in inverse emulsion to affect the distribution of the particles of the emulsion in size and, thus, to adjust the average size and particle size distribution agglom the drugs. Under the variance of the mean, depending on the content of surface-active substances and energy shift arising from the emulsification, heterogeneous systems, which can be

- suspensions

- emulsion

the microemulsion.

These various dispersed forms allow you to adjust the dispersion of the particles of the microgels in the range from 50 nm to 100 μm.

Chemical conditions of synthesis of the polymer (type monomers, catalysts, initiators) allow you to control individual properties of the obtained polymer (average molecular weight, degree of crosslinking, anionic character).

Synthesized thus adjuvant is in the form of an emulsion type "drops of polymer in oil" or "reversible latex". When the emulsion is dispersed in an aqueous solution of the antigen containing physiological buffer is the address of the emulsion, it is dispersed to form a liquid and transparent dispersion of polymer microgels in water. For example, drops microgels polyacrylate sodium can have an average size in the range of 0.5-5 micrometers, such as about 2 micrometers.

Reversible latexes and methods for their preparation are described, for example, in WO 99/36445 (see, in particular, the examples on page 9 and subsequent WO 99/36445).
