objective(s): despite treatment with antibiotics and vaccination with bcg, tuberculosis (tb) is still considered as one of the most important public health problems in the world. therefore, designing and producing a more effective vaccine against tb seems urgently. in this study, immunogenicity of a fusion protein which consisting or comprising cfp-10 from mycobacterium tuberculosis and the fc-...

A tissue culture method using MDCK cells grown under serum-free conditions was developed to produce an inactivated influenza subunit vaccine. The first clinical data suggest it to be equal to the conventional egg-derived influenza subunit vaccine. In a double-blind controlled trial, 2 groups (n = 57 each) of adult volunteers were immunized with experimental bivalent influenza subunit vaccine de...

Background: Enterotoxigenic Escherichia coli (ETEC) strains are the major causes of diarrheal disease in humans and animals. Colonization factors and enterotoxins are the major virulence factors in ETEC pathogenesis. For the broad-spectrum protection against ETEC, one could focus on colonization factors and non-toxic heat labile as a vaccine candidate. Methods: A fusion protein is composed of a...

Abstract Achieving sufficient worldwide vaccination coverage against SARS-CoV-2 will require additional approaches to currently approved viral vector and mRNA vaccines. Subunit vaccines may have distinct advantages when immunizing vulnerable individuals, children pregnant women. Here, we present a new generation of subunit targeting antigens CD40-expressing antigen-presenting cells. We demonstr...

Infectious bursal disease virus (IBDV) is a highly contagious pathogen that causes damage in lymphoid organs and remains a threat to the poultry industry worldwide. Currently, subunit vaccines based on VP2 antigen expressed in prokaryotic systems are widely used in clinical settings. However, the immunogenicity of VP2 vaccines is limited because of their inherent defect that the structure of th...

Objective(s): A new strategy in recent studies is using effective tuberculosis (TB) subunit vaccines combined with appropriate carriers and adjuvants which have shown promising results in preclinical and clinical studies. The aim of the present study was to evaluate the PLGA:DDA hybrid nanoparticles (NPs) for subcutaneous delivery of a novel multistage subunit vaccine ...

Specific humoral immune responses in a clinical trial on cattle for vaccines against contagious bovine pleuropneumonia (CBPP) were investigated. The trial included a subunit vaccine consisting of five recombinant putative variable surface proteins of the infectious agent Mycoplasma mycoides subsp. mycoides small colony type (M. mycoides SC) compared to the currently approved attenuated vaccine ...
