(1) technical field
The present invention relates to a kind of human influenza-poultry influenza combined vaccine and preparation method thereof, especially a kind of combined vaccine that comprises H1N1 type, H3N2 type, Type B influenza and H5N1 type avian influenza vaccine and preparation method thereof.
(2) background technology
On October 14th, 2005, WHO appealed to the world: " whole world is in the edge of another time flu outbreak at present; in case take place; propagate rapidly; will be infected less than 3 months All Countries; underestimate death toll 2,000,000 to 7,400,000; economic and society destroys huge, and each country of the whole world all must do some preparations ".
On JIUYUE 10th, 2003 1, and H5N1 bird flu case 387 people are taken place all over the world altogether, dead 245 people, case fatality rate is up to 63.3%, potential hazard surpasses SARS, the health that is threatening the people of the world, and the development of human-used avian influenza vaccine has caused the great attention of national governments.
According to statistics international pharmacy corporation community of association (IFPMA) in January, 2006, comprise that 12 (14) units of states such as method, American and Britain, moral, day, Australia, Russia, Belgium, (China) have carried out the research of human H5N1 vaccine to global avian influenza vaccine anthroposcopy.In April, 07, the U.S. is the H5N1 vaccine listing of first approval Pasteur S.A. in the world, and the said firm announces, will donate 6,000 ten thousand doses of H5N1 vaccines to World Health Organization (WHO) in 3 years and be used for global reserves.China also ratifies Ke Xing company in June, 08 and produces avian influenza vaccine, as emergent during the course of the Olympic Games stock vaccine.
The difficult problem that present avian influenza vaccine manufacturer runs into is the question of market.It is generally acknowledged: bird flu patient surrounding population and close contact birds person should inoculate this vaccine, and need to carry out prophylactic immunization for broad masses of the people? this question answering is negated, because can H5N1 virus cause human-to-human transmission, be a unknown number, generally inoculation, cost is too high, thereby at present only as technical reserve, or goods and materials stock, because product does not have market, have influenced the enthusiasm that manufacturer invests and develops avian influenza vaccine.
Now, the crowd inoculates the seasonal current influenza vaccine and constantly enlarges, and especially developed country is comparatively general, reaches 27% as U.S.'s rate of vaccination, and European countries' rate of vaccination does not wait 7.8%~17.7%.China also constantly enlarges, if add human-used avian influenza vaccine in the human influenza vaccine, cost is not high easily to be accepted by people again.
(3) summary of the invention
The object of the invention provides a kind of human influenza-poultry influenza combined vaccine, adds human-used avian influenza vaccine in the human influenza vaccine, and cost is not high easily to be accepted by people again, and has solved the problem of avian influenza vaccine inoculation difficulty.
The technical solution used in the present invention is:

12) the matched group rabbit is at experimental session, the same blood sampling simultaneously with experimental rabbit, and the result does not all detect influenza A1, Type B and H5N1 avian influenza antibody except that the A3 type influenza neutralizing antibody that detects similar titre, show that contrast sets up.
8, antibody test result sums up:
1) exempt from preceding rabbit antibody check result:
(1) do not find the neutralizing antibody of H 5 N 1 avian influenza and influenza Type B;
(2) detect the influenza A1 type neutralizing antibody that hangs down titre individually;
(3) very high influenza A3 type neutralizing antibody is generally arranged.
2) contain the inoculation of bird flu antigen vaccine:
(comprise bird flu epidemic disease unit price Seedling and people-bird flu unite 4 valency vaccines)
Behind 1 pin: no adjuvant or adjuvant Seedling all are not checked through neutralizing antibody.
Behind 2 pins: no adjuvant or adjuvant Seedling all are checked through neutralizing antibody, all〉1:20.
3) contain the inoculation of A type antigen vaccine:
(comprise human influenza 3 valency vaccines and people-bird flu unite 4 valency vaccines)
Behind 1 pin: no adjuvant or adjuvant Seedling, all check average〉the A type neutralizing antibody of 1:20;
Behind 2 pins: no adjuvant or adjuvant Seedling, all be checked through very high A type neutralizing antibody,

7) detect the result that blood in the immunizing rabbit serum presses down antibody, similar to neutralizing antibody, because neutralizing antibody directly reflects the ability of virus killing, experimental result is stable, objective again, though and blood to press down the antibody method easy, the influence factor is more, reliability is not as neutralizing antibody.
9, as can be known: the associating of human influenza vaccine and avian influenza vaccine from The above results, substantially do not disturb, particularly do not have the adjuvant Seedling, even indivedual adjuvant Seedling is disturbed by some, but all produced higher neutralizing antibody, uniting of 2 kinds of vaccines of prompting is fully possible.
10, the equal acute safety testing by mice and Cavia porcellus of 6 seedlings.
11, the imagination of manufacturer-bird flu combined vaccine:
Technology: split vaccine-adult, child are suitable for.
Dosage form: no adjuvant Seedling-transparency liquid, with traditional influenza Seedling, easily promote; Or aluminium hydroxide adjuvant (0.5mg/0.5ml) vaccine, its immune effect is better.
Dosage: confirmer's influenza 1 pin of each 15 μ g-, bird flu 2 pins are effective.
Program: 1 pin is used to prevent human influenza; And, strengthen 1 pin when needing the burst birds flu-preventing again as the bird flu fundamental immunity.
2 pins are used for bird flu epidemic-stricken area resident, with the key population that contacts birds.
12, the same with influenza vaccines, along with the whole society annual constantly repeated inoculation and popularization, make the H5N1 avian influenza antibody in the crowd, constantly strengthen and enlarge, may reach the same like this with present H1N1 influenza, even H5N1 virus obtains the ability of human-to-human transmission, and is also not fearful.
