Abstract

The present invention relates to a field of a vaccine adjuvant, more specifically a novel self-emulsifying vaccine adjuvant and a preparation method thereof. The adjuvant of the present invention is composed of 15 to 98% of oil phase, 1 to 30% of hydrophilicity surface active agent, 1 to 30% of lipophilicity surface active agent and 0 to 20% of assisted emulsifying agent. Compared with a similar adjuvant supplied in the market at present, the vaccine adjuvant of the present invention not only has the same self-emulsifying effect as the similar adjuvant but also has the advantages of better stability and lower cost.

Description

A kind of self-emulsifying vaccine adjuvant and preparation method thereof
Technical field
The present invention relates to the vaccine adjuvant field, be specifically related to vaccine adjuvant of a kind of new self emulsifying and preparation method thereof.
Background technology
Though antigenic specificity and hypotoxicity that highly purified new generation vaccine tool is good, immunogenicity is low, and need cooperating efficiently, adjuvant uses.Adjuvant is prior to antigen or is injected in simultaneously in the animal body, can change non-specificly or enhancing body to the material of antigenic specific immune response, also claim immunostimulant.
Because it is complicated that vaccine development becomes day by day, equally adjuvant also had higher requirement; Biological example chemistry expert finds: (effectively antigen typically refers to the ingredient of those energy immune response stimulatings in antibacterial or the virus earlier the effective antigen in the vaccine to be carried out purification, also claim main immunizing antigen), antigen behind the purification can improve immune effect, reduce or avoid part side effect (untoward reaction), this vaccine is called subunit vaccine.But, these less relatively less immunizing antigens will come enhance immunity reaction relying on vaccine adjuvant to a greater extent; Improvement innovation on other manufacturing technologies, as delay the antigen rate of release, can prolong the immune effect duration of vaccine, these all are the result who improves vaccine adjuvant usually.So research and develop new adjuvant technology, stimulate the immunity that produces and make vaccine (human and for animals) more effective safer thereby improve vaccine antigen, this is the major fields that global each big vaccine manufacturer researches and develops.
Oil emulsion vaccine is one of type that product is maximum on the at present domestic and international vaccine market, and oil emulsion vaccine has three types: 1) Water-In-Oil (W/O) type.This dosage form is used the most general, and remarkable advantage is to obtain high-level persistent immunoenhancement result.Shortcoming is than thickness, and injection is difficulty.2) oil-in-water (O/W) type.Set up this method for reducing in the Emulsion oil content, but widespread usage not.This dosage form advantage is that viscosity is low, is easy to injection, and shortcoming is a little less than the immunogenicity, only produces more weak immunne response in the induced animal body.3) W/O/W (W/O/W) type.The w/o type vaccine is prepared through being distributed to for the second time aqueous phase.Purpose is to reduce viscosity, not only has been convenient to inject but also have good immunogenicity, and this dosage form is with the advantage of w/o type and O/W type, and effect is fine.But difficulty is bigger on the technology of preparing, and vaccine stability is poor, if can overcome this shortcoming, and it is optimal emulsion vaccine.
The best import vaccine adjuvant commodity of generally acknowledging by name 206 (are called in the following text: the import adjuvant) prepared W/O/W type emulsion vaccine by the self emulsifying technology both at home and abroad, solved the difficult problem of W/O/W type emulsion vaccine preparation, and have certain stability, obtained extensive use in the world.Its weak point is that prepared W/O/W type emulsion vaccine stability is also not too satisfactory.Therefore, prepare stable W/O/W type Emulsion by the self emulsifying technology and have extremely important realistic meaning and market value.
The present invention also by the self emulsifying technological development a kind of new self-emulsifying vaccine adjuvant, solve W/O/W type emulsion vaccine and prepared problem of difficult, prepared emulsion vaccine not only is convenient to inject but also have good immunogenicity, and the stable W/O/W type emulsion vaccine more prepared than import adjuvant is better.
Summary of the invention
The invention discloses a kind of new self-emulsifying vaccine adjuvant and preparation method thereof, solved W/O/W type emulsion vaccine by the self emulsifying technology and prepared problem of difficult, the prepared W/O/W type emulsion vaccine stability W/O/W type emulsion vaccine more prepared than existing adjuvant is better.
Self-emulsifying vaccine adjuvant of the present invention, form by following component and percentage by weight:
Oil phase 15-98%
Hydrophilic surfactant active 1-30%
Lipophilic surfactant 1-30%
Co-emulsifier 0-20%
Each weight percentages of components is all in the adjuvant gross weight.
Preferred ingredients and percentage by weight are formed:
Oil phase 35-85%
Hydrophilic surfactant active 6-25%
Lipophilic surfactant 6-25%
Co-emulsifier 3-15%
Each weight percentages of components is all in the adjuvant gross weight.
Aforesaid vaccine adjuvant, wherein oil phase is one or more in mineral oil, vegetable oil, benzyl benzoate, the ethyl oleate etc.
Aforesaid vaccine adjuvant, wherein the hydrophilic surfactant active is HLB value one or more in the surfactant more than 8, as polyoxyethylene nonyl 2, 2-Oxydiphenol (polyoxyethylene nonylphenol ether), polyoxyethylene aliphatic alcohol ether (milky white clever A), sad certain herbaceous plants with big flowers acid polyethylene glycol glyceride (Labrasol), polysorbas20, polysorbate40, polysorbate60, Tween 80, sorbimacrogol oleate100, polysorbate85, polyoxyethylene hydrogenated Oleum Ricini, pluronic F-68, polyoxyethylene lauryl alcohol alcohol ether etc.
Aforesaid vaccine adjuvant, wherein lipophilic surfactant is one or more in the surfactant of HLB value between 3-8, as lecithin, fabaceous lecithin, sorbester p37, span 83, sorbester p17, sorbester p38, sorbester p18, glyceryl monostearate, glyceryl monooleate, the single oleic acid sorbitol ester etc. that contracts.
Aforesaid vaccine adjuvant, wherein co-emulsifier is selected from one or more in Macrogol 200, Liquid Macrogol, PEG400, ethanol, propylene glycol, oleic acid, 18-amine., the octadecanol etc.
The inventor finds that after test of many times preferred component of vaccine adjuvant and weight consist of:
White oil 60-73%
Sad certain herbaceous plants with big flowers acid polyethylene glycol glyceride and/or tween 5-12%
Single oleic acid contract sorbitol ester and/or span 10-20%
Oleic acid 3-9%
Each weight percentages of components is all in the adjuvant gross weight.Under this component and percentage by weight, the stability of vaccine adjuvant is better.
The preparation method of vaccine adjuvant of the present invention: take by weighing recipe quantity emulsifying agent, co-emulsifier and oil phase mix homogeneously, obtain adjuvant.
Vaccine adjuvant of the present invention is compared with the similar adjuvant of supply in the market, has not only had the self emulsifying effect same with it, and stability is better, and primary raw material is homemade, and it is nearly 40% that cost has reduced, and has economic worth and market potential.
Prepare oil emulsion vaccine with vaccine adjuvant of the present invention and import adjuvant (trade name 206) with same method, carry out stability test, immunoprotection test and field test respectively simultaneously.
1 oil emulsion vaccine stability test
The adjuvant 2000ml that will be preheated to 30 ℃ earlier is added in the mulser, stirs, and slowly adds to be preheated to 30 ℃ antigen liquid 2000ml (antigen: oily adjuvant=1: 1 in stirring, V/V), add the back and stirred 15 minutes, make its uniformity after, emulsifying is promptly finished in emulsifying 5 minutes.Under aseptic condition, open the mulser bottom valve then, pour in the serum bottle of the 10000ml through doing roasting sterilization, from serum bottle, divide again in the 100ml plastic bottle that is filled to after the sterilization, add the sterilization plug, the jewelling lid.Centrifugal, viscosity and outward appearance detect.And respectively at depositing under the room temperature condition to observe its stability.Experimental result sees Table 1,2,3.
