Abstract

The invention discloses a preparation method of a novel adjuvant of an oil emulsion inactivated vaccine and a use method of the novel adjuvant in an oil emulsion inactivated vaccine and belongs to the technical field of preparation and use of the veterinary oil emulsion inactivated vaccine. The preparation method comprises taking a transfer factor diluent, carrying out filtration and degerming, adding tween-80 into the diluent according to a ratio to obtain a water phase, preparing an oil phase from white oil for injection and Span-80 according to a ratio, and carrying out emulsification on the water phase and the oil phase according to a ratio of 1: 2-1: 3 at a temperature of 15-35 DEG C at a rotation rate of 2500-3500rpm for 15-30min. The invention discloses a method for preparing an oil emulsion inactivated vaccine from the adjuvant. The method comprises carrying out emulsification mixing on the adjuvant and a routine vaccine according to a ratio of 1: 3 to 1: 4 to obtain a novel adjuvant vaccine. The novel adjuvant vaccine has immunization effects obviously better than those of the routine vaccine and has a short immunization blanking period and a uniform immunization antibody level higher than that of the routine vaccine.

Description

The preparation of a kind of oil-emulsion inactivated vaccine novel adjuvant and application process
Technical field
The present invention relates to the preparation of a kind of oil-emulsion inactivated vaccine novel adjuvant, and this adjuvant is oil emulsion inactivated Application process in Seedling, this invention can realize strengthening the technology requirement of inactivated vaccine immune effect.
Background technology
China breeding environment is complicated, and animal epidemic and pesticide, residual shine into meat product outlet of veterinary drug medicine are seriously damaged Lose.Reduce Animal diseases, it is to avoid prolonged application antibiotic, develop high-quality, nuisance free meat products, Cai Nengbao The sustainable and healthy development of card China aquaculture.
At present, prevent and control zoonosis in addition to safety measure, relying primarily on vaccine immunity, particularly By the immunoprophylaxis of oil emulsion vaccine.For oil-emulsion inactivated vaccine, normal conditions can after immune 14 days Produce antibody, how can evoke immunity in the shorter time, improve immune effect, need to add adjuvant with Strengthen them and induce immunoreactive ability.
In inactivated vaccine, adjuvant is applied with antigen simultaneously, it is possible to strengthen collective's immunne response energy for antigen Power, or change immunoreation type.Its function mainly has: use position to solicit immunocyte and immune molecule, Strengthen immunne response;Strengthen vaccine antigen transmission;Promote immunity contact, strengthen poor antigen immunogenicity and Immunological memory, changes the configuration of antigen;Change the kind of humoral antibody, IgG hypotype and the affinity of antibody, And cellular immunization and mucosa-immune effect.Preferably adjuvant does not only have immunogenicity also energy enhancing body Immunne response, it is possible to make body obtain optimal protective immunity and immunological memory.Relevant immunostimulant side The research in face, the most, it is concentrated mainly on herbal polysaccharide, cytokine, interferon, gathers Flesh born of the same parents etc., the most also one is commonly recognized immunostimulant---and transfer factor, current veterinary drug industry is There are many families in batch production.Transfer factor (Thansfer Factor is called for short TF) is that human or animal's sensitization is the thinnest A kind of lower-molecular substance that can shift sensitization information in the multiple factor of born of the same parents' release.Since nineteen ninety-five Since Lawrence finds transfer factor (Transfer factor).The research of transfer factor is got more and more by people. Owing to its molecular weight is little, nontoxic, no antigen, does not causes allergic reaction, do not produce neutralizing antibody and can surpass Get over the advantages such as germline boundary application, and at treatment immunodeficiency, malignant tumor, various infectious disease etc. All obtaining certain curative effect in the test of aspect, therefore transfer factor has broad prospects in clinical practice.
Transfer factor has dialyzability, can be combined and no antigen itself with antigen.Transfer factor with The specific immunity information of primed lymphocyte, it is possible to the special antigenicity that donor is had and acumen thereof Transspecific give immunoreation negative receptor, receptor produces a delayed hypersensitivity energy simultaneously Power.Transfer factor has premunition information, excites immunologic cellular activity, regulation immunologic function, enhancing machine Body non-specific immunity etc. act on, and are described as the triggering agent of T cell activity, the reinforcing agent of cellular immunization, Cell immunomodulator and interferon produce and start agent.
Transfer factor solution coordinates attenuated vaccine to use, it is verified that the immune effect of vaccine can be improved, but Not yet have been reported that transfer factor as the research report of oil-emulsion inactivated vaccine adjuvant.
Summary of the invention
The present invention is that inactivated vaccine provides a kind of new immunological adjuvant-transfer factor, and utilizes this adjuvant system The new method of standby inactivated vaccine.This vaccine is not only able to shorten the blank phase of oil-emulsion inactivated vaccine, also can improve The antibody titer of inactivated vaccine, has positive effect to improving vaccine protection.
The present invention is to be achieved through the following technical solutions:
The raw material of adjuvant of the present invention consists of:
Aqueous phase:
Transfer factor 94%~96%
Tween 80 4%~6%
Oil phase:
Si Ben-80 5%~6%
Injection white oil 95%~94%
Aluminium stearate 0.5%~2%
Wherein said Material Percentage is volume ratio;
Wherein the content of peptides of transfer factor is 2.5~5.5mg/ml, and Ribose concentration is 50~100ug/ml, and transfer factor comes Source is broiler spleen, laying hen spleen or Lien Sus domestica.
Wherein aqueous phase is 1: 2~1: 3 with the ratio of oil phase.
The adjuvant prepared and conventional vaccine are prepared from according to 1: 3~1: 4 ratio mixing and emulsifying.
Take above-mentioned raw materials, be prepared as vaccine adjuvant according to following technique
The preparation method of vaccine adjuvant of the present invention is:
Taking transfer factor diluent through 0.22um filtration sterilization, add tween 80 according to the above ratio, 37 DEG C shake up, Hatching 1~2h, be prepared as aqueous phase, oil phase boils according to aforementioned proportion, 121 DEG C of sterilizings 30 minutes.? Carrying out emulsifying at 15~35 DEG C, rotating speed is 2500rpm~3500rpm, and the time is 15~30min.After emulsifying completes, Mixing according to the ratio of 1: 3~1: 4 with conventional vaccine, continue emulsifying 10~15min, emulsifying rotating speed is 2500rpm~3500rpm, treats that vaccine dosage and stability reach requirement.
The oil emulsion vaccine that the present invention makes, joins in vaccine using transfer factor as immunostimulant, Ke Yiyou Effect improves the response of immunocyte, the submission of quickening antigen, and then shortens the Blank immunization phase of antigen, carries High antibody horizontal, it is possible to activating immune system, eliminates immunosuppressant.
