OBJECTIVES Effective vaccines against the highly pathogenic influenza A/H5N1 virus are being developed worldwide. In Japan, two adjuvanted, inactivated, whole-virion influenza vaccines were recently developed and licensed as mock-up, pre-pandemic vaccine formulations by the Ministry of Health and Labor Welfare of Japan. During the vaccine design and development process, various obstacles were o...
Once a burgeoning field of study, over the past decade or so, T cell epitope discovery has lost some luster. The contributory factors perchance are the general notion that any newly discovered epitope will reveal very little about an immune response and that knowledge of epitopes are less critical for vaccine design. Despite these notions, the breadth and depth of T cell epitopes derived from c...
Pathogens rely on proteins embedded on their surface to perform tasks essential for host infection. These obligatory structures exposed to the host immune system provide important targets for rational vaccine design. Here, we use a systematically designed series of multi-domain constructs in combination with small angle X-ray scattering (SAXS) to determine the structure of the main immunoreacti...
objective: several vaccines against hiv have been investigated but none has been approved as an effective hiv vaccine. an approach that could induce stronger immune response against the pathogen is utilizing a multi-epitopic vaccine. this strategy was used in the design of several vaccines and resulted in improved immune responses. materials and methods: in this study a multi-epitopic fusion p...
Dengue fever (DF) and dengue hemorrhagic fever (DHF) are mosquito-transmitted diseases of global importance. Despite significant research efforts, no approved vaccines or antiviral drugs against these diseases are currently available. This brief article reviews the status of dengue vaccine development, with particular emphasis on the vaccine strategies in more advanced stages of evaluation; the...
Background: Human colorectal cancer cells overexpress carcinoembryonic antigen (CEA). CEA is a glycoprotein which has shown to be a promising vaccine target for immunotherapy against colorectal cancer. Objective: To design a DNA vaccine harboring CEA antigen and evaluate its effect on inducing immunity against colorectal cancer cells in tumor bearing mice. <str...
Background and Objectives: The Haemophilus influenzae (Hib) conjugate vaccine (HibCV) using a pentavalent formulation was introduced to the Iranian routine immunization program from November 2014. Iran is preparing to include Pneumococcal conjugate vaccines (PCV), as well. Measuring and monitoring the impact of HibCV and PCV are necessary to provide evidence for introduction and sustained admin...
BACKGROUND The 7-valent pneumococcal conjugate vaccine (PCV-7) was introduced in the United Kingdom in 2006 with a 2, 3 and 13 month schedule, and has led to large decreases in invasive pneumococcal disease (IPD) caused by the vaccine serotypes in both vaccinated and unvaccinated cohorts. We estimated the effectiveness of PCV-7 against IPD. METHODS AND FINDINGS We used enhanced surveillance d...
objective(s):brucellosis, especially caused by brucella melitensis, remains one of the most common zoonotic diseases worldwide with more than 500,000 human cases reported annually. the commonly used live attenuated vaccine in ovine brucellosis prophylaxis is b. melitensis rev1. but due to different problems caused by the administration of this vaccine, a protective subunit vaccine against b. me...
The extraordinary genetic diversity and immune evasion of human immunodeficiency virus (HIV) pose significant challenges for vaccine development. AIDS vaccine design requires a scientifically driven, rational approach that encompasses the latest advances in viral molecular genetics, structural biology, and immunology.
