an experimental inactivated oil-emulsion h9n2 avian influenza vaccine was formulated with 3 parts ofinactivated avian influenza antigen a/chicken/iran/101/1998(h9n2) emulsified in 7 parts of oil adjuvant.twelve week-old specific pathogen-free (spf) chickens were divided into seven groups of 10 birds. sixgroups were vaccinated with 1, 1/10th, 1/50th, 1/100th, 1/200th and 1/400th field dose of th...
The immunogenicities and efficacies of a licensed diphtheria, tetanus, acellular pertussis, and inactivated poliovirus vaccine and the same vaccine formulated in a liposome/oil emulsion adjuvant were compared in a mouse model of pertussis respiratory infection. A single dose of the liposome/oil emulsion-adjuvanted vaccine produced significantly higher antibody levels than one dose of the licens...
In order to control the H9N2 subtype low pathogenic avian influenza (LPAI), an inactivated vaccine has been used in Korea since 2007. The Korean veterinary authority permitted the use of a single H9N2 LPAI vaccine strain to simplify the evolution of the circulating virus due to the immune pressure caused by the vaccine use. It is therefore important to determine the suitability of the vaccine s...
a study has been carried out for determining of cross-immunity between massachusetts (mass) m41 and iranian ir/773/2001 (793/b) strains of infectious bronchitis virus. two groups of 20 three weeks old spf chickens vaccinated subcutaneously with two oil-emulsions inactivated infectious bronchitis vaccines (mass m41 and iranian ir/773/2001 strains) that had been manufactured in razi institute in ...
Two oil emuisified vaccines of Newcaslte disease were prepared from Lasota strain. The virus was propagated in 9-day-old chicken embryos through allantoic route. The haemagglutination titre of the allantoic fluid used for vaccine preparation was 2048. The fluid was inactivated by 0.1 per cent f nal concentration of formalin at 37 oc for 6 hours. Inactivated allantoic fluid was emulsified with a...
This experiment was conducted by using (32000) chicks classified into three houses (18000 chicks in first house, 5000 chicks in second house and 9000 chicks in third house). The first group was inoculated with inactivated oil emulsion vaccine contain NDV (La Sota) and AIV (H9N2) subcutaneous at one day, in the same time vaccinated with mixed vaccine of NDV (La Sota) and IBV H120 by spraying rou...

Purpose The first aim of this study was to develop a novel inactivated porcine epidemic diarrhea virus (PEDV) vaccine using the recently isolated Korean PEDV QIAP1401 strain and to evaluate its protective efficacy in growing pigs. The second was to determine the optimum adjuvant formulation of the inactivated PEDV vaccine that induces protection against viral challenge. Materials and Methods ...
Influenza directly or indirectly contributes to the four leading causes of global mortality, at rates that are highest in older adults. As the proportion of older adults in the Korean population is greater than in most other countries, influenza prevention is a greater public health priority in Korea than elsewhere. Conventional inactivated influenza vaccine (IIV) is less immunogenic and effica...
The immunologie efficacy of inactivated oil-emulsion vaccines against Newcastle disease (ND) and avian influenza (AI) by use of embryo vaccination technology was evaluated. The vaccine antigens were prepared from LaSota strain of ND and H9N2 strain of AI viruses. These antigens were emulsified with an oil adjuvant. 18-day-old embryonated eggs from Aryan broiler breeder were divided into three g...
