Objective(s): Vaccination is one of the most effective means to protect humans and animals against brucellosis. Live attenuated Brucella vaccines are considered effective in animals but they may be potentially infectious to humans, so it is vital to improve the immunoprotective effects and safety of vaccines against Brucella. This study was designed to evaluate the immunogenicity of DNA vaccine...
background: dna immunization with plasmid dna encoding bacterial, viral, parasitic, and tumor antigens has been reported to trigger protective immunity. the use of plasmid dna vaccinations against many diseases has produced promising results in animal and human clinical trials; however, safety concerns about the use of dna vaccines exist, such as the possibility of integration into the host gen...
toxoplasmosis is a worldwide infection which is commonly asymptomatic but can cause serious medical problems in immunocompromised individuals and fetus. the infection also causes considerable economic loss because of abortion in livestock, mostly in sheep and goats. dna vaccination may be a powerful approach against intracellular parasites such as toxoplasma gondii. the goal of this study was t...
conclusions the results of this study demonstrated that the tpasp-padre-truncated orf2 gene cassette and the truncated orf2 gene in recombinant plasmids are successfully expressed in eukaryotic cells. the immunogenicity of the two recombinant plasmids with different formulations will be evaluated as a novel dna vaccine in future investigations. results sequence analysis and bioinformatics studi...
AIM To test the feasibility of delivering a plasmid encoding IL-15 as a DNA vaccine adjuvant for improving the immune responses induced by hepatitis B virus core gene DNA vaccine. METHODS We used RT-PCR based strategies to develop IL-15 expression constructs. We first confirmed that the gene could be expressed in Escherichia coli due to the poor expression of IL-15. Then the bioactivity of IL...
With advent and development of DNA recombinant technology and advantages of p. pastoris expression system, fusion (F) protein of PPRV expression, because of effective immunodominant role could be an appropriate candidate for production of recombinant vaccine against PPR disease. In this study, F gene of PPRV Nigeria 75/1 strain (1637 bp) was amplified using RT-PCR and purified. It was then cl...

A phase I safety and immunogenicity study investigated South African AIDS Vaccine Initiative (SAAVI) HIV-1 subtype C (HIV-1C) DNA vaccine encoding Gag-RT-Tat-Nef and gp150, boosted with modified vaccinia Ankara (MVA) expressing matched antigens. Following the finding of partial protective efficacy in the RV144 HIV vaccine efficacy trial, a protein boost with HIV-1 subtype C V2-deleted gp140 wit...
Estimating effective doses of novel HIV vaccines is challenging. Dose-response analyses of DNA and fowlpox virus HIV vaccines showed that 1 mg of DNA vaccine and 5 x 10(7)pfu of fowlpox virus booster was immunogenic in macaques. However, this dose was poorly immunogenic in humans. When adjusted for body surface area, the human dose studied was equivalent to a poorly immunogenic lower dose in mo...
AIM To assess the efficacy and safety of in vivo electroporation (EP)-mediated dual-plasmid hepatitis B virus (HBV) DNA vaccine vs placebo for sequential combination therapy with lamivudine (LAM) in patients with chronic hepatitis B. METHODS Two hundred and twenty-five patients were randomized to receive either LAM + vaccine (vaccine group, n = 109) or LAM + placebo (control group, n = 116). ...
