The prime–boost response induced by different combinations of four H5N1 vaccines (NIBRG-14 (clade 1), Indo05/2005(H5N1)/PR8-IBCDC-RG2 (clade 2.1), A/Bar-Headed Goose/Qinhai Lake/1A/05 SJ163222 (clade 2.2), and Anhui01/2005(H5N1)-PR8-IBCDC-RG5 (clade 2.3.4)) was evaluated in mice. Clade 1-primed BALB/c mice showed a booster response to all of the other three H5N1 vaccines. Clade 2.2 vaccine was also...
The safety of intranasal live-attenuated influenza vaccine (LAIV) in immunocompromised children with cancer is unknown. The objective of this study was to describe the safety and immunogenicity of LAIV in mild to moderately immunocompromised children with cancer.We conducted a multicenter, randomized, double-blind study of LAIV versus placebo in children aged 5–17 years with cancer. LAIV (frozen formulation)...
Studies on rotavirus vaccine shedding and its potential transmission within households including immunocompromised individuals are needed to better define the potential risks and benefits of vaccination. We examined fecal shedding of pentavalent rotavirus vaccine (RV5) for 9 days following the first dose of vaccine in infants between 6 and 12 weeks of age. Rotavirus antigen was detected by enzyme...
Common variable immunodeficiency (CVID), the most frequent primary antibody disorder, is characterized by hypogammaglobulinaemia and impaired antibody production. Poor vaccination response is essential for the diagnosis of CVID. Their under laying defects remain to be elucidated. Routine determination of antibody production in serum from CVID patients after vaccination and investigation of B cell...
Lactococcus is a genus of Gram positive food-grade bacteria that has been widely used as a vaccine platform for the safe delivery of heterologous antigens. Many reports support the involvement of inflammation and immunity in atherosclerosis as well as the role of autoimmunity to heat shock proteins (HSPs) in the progression of atherogenesis. In this study, experiments were specifically designed to...
The aim of this study was to understand the use and distribution of human rabies post exposure prophylaxis (PEP) vaccine in Bhutan and to identify risk factors for receiving an incomplete course of the vaccine. We analyzed post exposure treatment records from 28 medical hospitals from 2005 to 2008. Males (59%) accounted for significantly more PEP events than females (41%) across all age groups (P<0...
Group B streptococcus remains an important neonatal pathogen in spite of widely adopted intrapartum antibiotic administration; therefore immune prophylaxis for GBS infections is highly warranted. In passive immunization and lethal challenge studies with multiple GBS strains, we characterized the protective effect of rabbit polyclonal and murine monoclonal antibodies specific for four multi-functional...
Ross River Virus has caused reported outbreaks of epidemic polyarthritis, a chronic debilitating disease associated with significant long-term morbidity in Australia and the Pacific region since the 1920s. To address this public health concern, a formalin- and UV-inactivated whole virus vaccine grown in animal protein-free cell culture was developed and tested in preclinical studies to evaluate immunogenicity...
Edwardsiella tarda and Vibrio harveyi are Gram-negative bacterial pathogens that affect a wide range of cultured fish. In previous studies, we have reported an E. tarda live vaccine ATCC15947 and a V. harveyi subunit vaccine DegQ. On the basis of these studies, in the present study we developed a cross protective vaccine against both E. tarda and V. harveyi by constructing a recombinant ATCC15947,...
Global access to advanced vaccine technologies is challenged by the interrelated components of intellectual property (IP) management strategies, technology transfer (legal and technical) capabilities and the capacity necessary for accelerating R&D, commercialization and delivery of vaccines. Due to a negative association with the management of IP, patents are often overlooked as a vast resource...
The objectives of this study were to detect the immunogenicity of a lipopolysaccharide (LPS) binding protein (LBP) mimic epitope peptide vaccine and evaluate its effect on controlling excessive and uncontrolled inflammatory reactions in mice with acute lung injury. The vaccine was prepared by mixing self-made LBP mimic epitope multiple antigen peptide (MAP) and Freund adjuvants in a proper proportion...
We aimed to estimate the societal costs of rotavirus cases among children less than 5 years in Kazakhstan, an upper-middle income country in Central Asia.Data on medical, non-medical and indirect costs were collected for 190 patients less than 5 years, hospitalized with severe diarrhea in 2009 in two pediatric hospitals. Data on resource use for moderate and mild diarrhea cases were obtained from...
The function of MyD88 signals for induction of adaptive immunity is still controversial. Here we investigate using a human papillomavirus (HPV) 16 E7 DNA vaccine on MyD88 knock out mouse model whether MyD88 signals are required for induction of Ag-specific antibody and cellular responses, as well as antitumor resistance. When injected intramuscularly with E7 DNA vaccines, MyD88 deficient mice displayed...
