BACKGROUND Highly pathogenic avian influenza H5N1 viruses remain a threat to human health, with potential to become pandemic agents. METHODS This phase III, placebo-controlled, observer-blinded study evaluated the immunogenicity, cross-reactivity, safety, and lot consistency of 2 doses of oil-in-water (AS03(A)) adjuvanted H5N1 A/Indonesia/05/2005 (3.75 μg hemagglutinin antigen) prepandemic ca...
Brucellosis is a zoonotic disease transmitted to humans either from animals or from their products.Although brucellosis can be found worldwide, the Mediterranean Basin, South and Central America, EasternEurope, Asia, Africa, the Caribbean, and the Middle East have currently been listed as high-risk regions. Thegenus Brucella is classified in at least nine species. Brucella melitensis is the glo...
Abstract Background and purpose: E. coli O157:H7 is one of the intestinal pathogens that mediate serious damages in gastrointestinal track. The bacterium attachment in large intestine is mediated via some colonization factors mainly Type III secretion proteins that are involved in this process. Among these factors, EspA protein plays an important role in system foundation. The aim of this ...
Background and Objectives: One of the ways to strengthen the effect of vaccines is using the adjuvant. STxB has a carrier and adjuvant role that we can fuse it with vaccine candidate antigens and produce efficient vaccines. BLF1 has a role in the pathogenesis and infection by Burkholderia pseudomallei, that can be studied when fused with stxB.The aim of this study expression blf1-stxB gene Cass...
Background: Chlamydia trachomatis is a silent, turbulent and unfortunately neglected bacterium which impairs human genital tract function. This Gram-negative obligate intracellular bacterium with unique life cycle and immunopathogenesis result in serious complications, such as Endometritis, pelvic inflammatory disease (PID), infertility, ability to ease HIV transmission and cofactor in human ...
The objective of this descriptive study was to determine Felis domesticus (cat) and Canis familiaris (dog) protein epitopes that bind strongly to selected HLA class II alleles to identify synthetic vaccine candidate epitopes and to identify individuals/populations who are likely to respond to vaccines. FASTA amino acid sequences of experimentally validated allergenic proteins of house cat and d...
BACKGROUND A candidate pandemic influenza H5N1 vaccine should provide rapid and long-lasting immunity against antigenically drifted viruses. As H5N1 viruses are poorly immunogenic, this may require a combination of immune potentiating strategies. An attractive approach is combining the intrinsic immunogenicity of virosomes with another promising adjuvant to further boost the immune response. As...
Trials of the HIV-1 vaccine have been conducted in Europe, North America, Brazil, China, and Thailand. The first trial of a candidate vaccine in Africa was recently completed in Uganda. It involved a randomised, placebo controlled trial of a vaccine in healthy volunteers at low risk of HIV infection. 3 The vaccine, called “ALVAC-HIV,” uses a live recombinant canarypox vector to express envelope...
The recent availability of significantly increased levels of funding for unmet medical needs in the developing world, made available by newly created public-private-partnerships, has proven to be a powerful driver for stimulating clinical development of candidate vaccines for malaria. This new way forward promises to greatly increase the likelihood of bringing a safe and effective vaccine to li...
Taiwan garnered international acclaim for its non-pharmaceutical measures to combat community transmission of covid-19. The island has now controversially fast tracked a local vaccine candidate. Andrew Silver asks why
