In the present study the effect of the locally produced genetic adjuvant of ginea pig specific CpG-motif-containing oligodeoxynucleotide (CpG-ODN) in an inactivated FMD virus vaccine was evaluated. Boosting the ginea pigs with FMD vaccine along with CpG-ODN adjuvant produced relatively higher ratio (5-fold) of FMDV-specific IgG2a / IgG1 than those vaccinated in the absence of CpG-ODN. The neutr...
Chikungunya virus has become a global health threat, spreading to the industrial world of Europe and the Americas; no treatment or prophylactic vaccine is available. Since the late 1960s much effort has been put into the development of a vaccine, and several heterogeneous strategies have already been explored. Only two candidates have recently qualified to enter clinical phase II trials, a chik...
newcastle disease (nd) is one of the most serious illnesses of chickens. live vaccines are widely used to prevent chicken from the disease all over the world. to access the effective and potentiate nd vaccine, a homogenous subpopulation from lasota strain was selected following cultivation of the virus on primary chicken embryofibroblast (cef) cells. pathogenicity indices and molecular characte...
Induction of cytotoxic T lymphocytes (CTL) is critical to cancer vaccine based immunotherapy. Efforts to elicit CTLs against tumor MUC1 with peptide based vaccine have not been successful in clinical application. We have design a MUC1 vaccine by replacing B cell epitope of CTB with MUC1 VNTR peptide. Immunization with hybrid CTB-MUC1 plus aluminum hydroxide and CpG adujuvant (CTB-MUC1-Alum-CpG)...
Prediction of immunogenicity is a substantial barrier in vaccine design. Here, a molecular dynamics approach to assessing the immunogenicity of nanoparticles based on structure is presented. Molecular properties of epitopes on nonenveloped viral particles are quantified via a set of metrics. One such metric, epitope fluctuation (and implied flexibility), is shown to be inversely correlated with...
The uniqueness of the dengue viruses (DENVs) and the spectrum of disease resulting from infection have made dengue vaccine development difficult. Several vaccine candidates are currently being evaluated in clinical studies. The candidate currently at the most advanced clinical development stage, a live-attenuated tetravalent vaccine based on the chimeric yellow fever-dengue virus (CYD-TDV), has...
in the last decades researchers had focused on developing a vaccine against tick based on protective antigen. recombinant vaccines based on concealed antigen from boophilus microplus have been developed in australia and cuba by the name of tickgard and gavac (de la fuente and kocan, 2006). further studies on this antigen have shown some extent of protection against other species (de vos et al.,...
background: bovine theileriosis results from infection with obligate intracellular protozoa of the genus theileria . the phylogenetic relationships between two isolates of theileria annulata , and 36 theileria spp . , as well as 6 outgroup including babesia spp . and coccidian protozoa were analyzed using the 18s rrna gene sequence. methods: the target dna segment was amplified by pcr. the pcr...
Abstract This article aims to discuss the perceptions and actions of public authorities regarding process introduction, production, conservation, distribution, application smallpox vaccine; emergence institutions associated with vaccine vaccination; its main obstacles in Bahia nineteenth century. The emphasizes local regional dynamics this process. It addresses problem colonial Bahia, arrival J...
In 1974, the World Health Organization (WHO) established the Expanded Program on Immunization (EPI) to ensure that all children have access to routinely recommended vaccines. Since then, global coverage with the four core vaccines (Bacille calmette guérin vaccine [for protection against tuberculosis], Diphtheria-tetanus-pertussis vaccine [DTP], Polio vaccine, and Measles vaccine) has increase...
