佐剂的剂型对疫苗稳定性、安全性及免疫效力均有一定的影响。为筛选优质佐剂以提高猪伪狂犬基因缺失标记灭活疫苗(JS2012ΔgE株)的免疫效果,分别使用水包油包水佐剂(ISA206)、水包油佐剂(ISA28VG)、油包水佐剂(ISA70VG)及水佐剂(Gel02)制备疫苗,并检测各组疫苗理化特性、安全性及免疫效力。结果显示:4种佐剂制备的猪伪狂犬灭活疫苗的理化特性、安全性均达到质量标准;免疫效力比较中,ISA70VG组相比其他免疫组具有较高的抗体水平且持续时间较长,其次为ISA206组;攻毒后,ISA70VG组和ISA206组无任何临床症状及病变。综合安全性及免疫效力,ISA206佐剂及ISA70VG更适合作为制备猪伪狂犬基因缺失标记灭活疫苗(JS2012ΔgE株)的佐剂。 相似文献

BackgroundNew-generation adjuvants for foot-and-mouth disease virus (FMDV) vaccines can improve the efficacy of existing vaccines. Chinese medicinal herb polysaccharide possesses better promoting effects.ObjectivesIn this study, the aqueous extract from Artemisia rupestris L. (AEAR), an immunoregulatory crude polysaccharide, was utilized as the adjuvant of inactivated FMDV vaccine to explore their immune regulation roles.MethodsThe mice in each group were subcutaneously injected with different vaccine formulations containing inactivated FMDV antigen adjuvanted with three doses (low, medium, and high) of AEAR or AEAR with ISA-206 adjuvant for 2 times respectively in 1 and 14 days. The variations of antibody level, lymphocyte count, and cytokine secretion in 14 to 42 days after first vaccination were monitored. Then cytotoxic T lymphocyte (CTL) response and antibody duration were measured after the second vaccination.ResultsAEAR significantly induced FMDV-specific antibody titers and lymphocyte activation. AEAR at a medium dose stimulated Th1/Th2-type response through interleukin-4 and interferon-γ secreted by CD4+ T cells. Effective T lymphocyte counts were significantly elevated by AEAR. Importantly, the efficient CTL response was remarkably provoked by AEAR. Furthermore, AEAR at a low dose and ISA-206 adjuvant also synergistically promoted immune responses more significantly in immunized mice than those injected with only ISA-206 adjuvant and the stable antibody duration without body weight loss was 6 months.ConclusionsThese findings suggested that AEAR had potential utility as a polysaccharide adjuvant for FMDV vaccines. 相似文献

Inactivated avian Metapneumovirus (aMPV) or turkey rhinotracheitis (TRT) virus vaccine was prepared from an Egyptian strain (Giza TRT-4). The virus was propagated in Vero cells and inactivated by binary ethyleneimine. The inactivated virus solution was tested for its sterility, purity, and safety. Then, it was mixed withNigella sativa oil as nonspecific immune-stimulant adjuvant. Physical characterization of oil prepared vaccine like viscosity and emulsion stability was investigated. An experiment was designed to evaluate the locally prepared aMPV vaccine in a comparison to commercial vaccines either inactivated or live attenuated. The obtained results showed that the locally prepared aMPV vaccine gave significantly higher humoral immune response when measured by ELISA and significantly higher cell mediated immunity by evaluating phagocytic activity of inoculated turkey poults with higher protection rate reached up to 100% after challenge with wild-type virus. 相似文献

Antibody responses of guinea-pigs, rabbits and pigs to inactivated porcine parvovirus vaccines 总被引:3,自引:0,他引:3
Antibody responses were compared in guinea-pigs, rabbits and pigs following vaccination with inactivated porcine parvovirus (PPV) vaccines. Mean PPV hemagglutination inhibition (HI) antibody titers of 52, 56 and 36 at 1 week after first vaccination and 896, 640 and 512 at 2 weeks after second vaccination were detected in guinea-pigs, rabbits and pigs, respectively. PPV vaccines prepared with greater concentrations of virus, as determined by hemagglutination (HA) units, and of aluminum hydroxide gel adjuvant, induced higher HI antibody titers in guinea-pigs. Optimal concentrations for inducing consistently high antibody titers consisted of vaccine virus with a HA titer of 256/0.1 ml and gel adjuvant at a final concentration of 50%. A second vaccination at 4 weeks compared to 2 or 3 weeks after first vaccination resulted in higher mean HI titers. These data provide preliminary information on the use of guinea-pigs or rabbits as laboratory animal models for testing the potency of PPV vaccines. 相似文献

In order to develop a safe vaccine against bovine ephemeral fever (BEF) which could be used in areas normally free of the disease, studies were carried out on inactivated virus vaccines. Initial experiments were carried out in cattle using virus vaccines that had been inactivated with β-propiolactone or formalin and then made-up in aluminium phosphate gel or Freund's incomplete adjuvant. A minimum inactivated virus dose of 106 PFU was necessary to stimulate a serum neutralizing antibody response in cattle. β-propiolactone inactivated BEF virus vaccines in Freund's incomplete adjuvant gave the best serum neutralizing antibody responses, producing high levels of neutralizing antibody with both high and low passage level virus. However, the magnitude of the antibody response bore little relationship to resistance of vaccinated animals to challenge with virulent BEF virus. A number of animals with high neutralizing antibody titres to BEF virus did not resist challenge. Using 500-fold less live virus at equivalent passage level to the low passage inactivated vaccine, similar or slightly lower antibody levels were attained, but most of the animals resisted challenge. It is suggested that the nature of the immune response and resistance to BEF infection may be complex and that reliance on serum neutralizing antibody as an indicator of resistance may give misleading results. 相似文献

Laboratory trials were carried out with an O2:K1 vaccine prepared with either the Freund's complete or incomplete adjuvant. Both types of vaccine administered subcutaneously were highly effective against a challenge with the vaccine strain within three to four weeks after vaccination at two to three weeks of age. The complete adjuvant vaccine was more effective than the incomplete adjuvant vaccine when administered to chickens of an earlier age, and in the rate of development and duration of immunity. The efficacy of both vaccines was unimpaired by their incorporation with the Newcastle disease oil adjuvant (inactivated) vaccine (Newcadin). The use of an oil adjuvant vaccine was not found to affect the rate of growth adversely or to produce any other reaction prejudicial to its commerical application. The efficacy of the vaccines was unimpaired by their incorporation with Newcastle disease oil adjuvant (inactivated) vaccine (Newcadin) thus demonstrating the possibility of producing a combined Escherichia coli/Newcastle disease virus vaccine. 相似文献
