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...

Rotavirus, the most common cause of severe diarrhea and a leading cause of mortality in children, has been a priority target for vaccine development for the past several years. The first rotavirus vaccine licensed in the United States was withdrawn because of an association of the vaccine with intussusception. However, the need for a vaccine is greatest in the developing world, because the bene...

The HIV/AIDS pandemic continues to spread and an AIDS vaccine is urgently needed. Regional alliances and international collaborations can foster the development and evaluation of the next generation of AIDS vaccine candidates. The importance of coordinating and harmonizing efforts across regional alliances has become abundantly clear. We recently formed the AIDS Vaccine for Asia Network (AVAN) ...

Since influenza may be prevented by vaccine, development and successful implementation of public health programs to prevent spread of a potential avian influenza strain relies upon vaccination as a strategic cornerstone. Although both the Department of Health and Human Services (HHS)† and the World Health Organization (WHO) highlight the role of influenza vaccination as the core of an effective...

Identification of an immune response to vaccination that reliably predicts protection from clinically significant infection, i.e. an immunological surrogate endpoint, is a primary goal of vaccine research. Using this problem of evaluating an immunological surrogate as an illustration, we describe a hierarchy of three criteria for a valid surrogate endpoint and statistical analysis frameworks fo...

The Bacille Calmette Guerin (BCG) vaccine can provide decades of protection against tuberculosis (TB) disease, and although imperfect, BCG is proof that vaccine mediated protection against TB is a possibility. A new TB vaccine is, therefore, an inevitability; the question is how long will it take us to get there? We have made substantial progress in the development of vaccine platforms, in the ...

Despite the fact that there had been multiple small outbreaks of Ebola Virus Disease, when a large outbreak occurred in 2014 there were no vaccines or drugs available for use. Clinical development of multiple candidate vaccines was then initiated in parallel with attempts to contain the outbreak but only one vaccine was eventually tested in a phase III trial. In order to be better prepared for ...

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...

the identification of a large number of antigens with potential for development of new tuberculosis vaccine has been accomplished in recent years. this study was designed for cloning and expression of esat-6 as a potent antigen of mycobacterium tuberculosis. selected gene (rv3875) was amplified by pcr and product was ligated into expressing plasmid vector pqe30 and recombinant pqe30-es plasmid ...
