Dendritic cells (DCs)-based vaccine was demonstrated to increase HIV specific cellular immune response; however, in some HIV-infected patients, the response to the vaccine resulted to be not effective. In order to understand if the outcome of the vaccination may be influenced by the host's genome and natural immunity, we studied the innate immune genome of HIV-infected patients previously vaccinated...
The filamentous bacteriophage are highly immunogenic particles that can be used as carrier proteins for peptides and presumably other haptens and antigens. Our previous work demonstrated that the antibody response was better focused against a synthetic peptide if it was conjugated to phage as compared to the classical carrier, ovalbumin. We speculated that this was due, in part, to the relatively...
Healthcare workers’ (HCWs) knowledge, attitudes, and beliefs regarding pertussis immunization were assessed and compared to the rate of vaccine uptake. A questionnaire was distributed to employees at a paediatric and maternity tertiary care centre. Respondents were then offered a dose of the tetanus, diphtheria, and acellular pertussis vaccine (Tdap) at a free vaccine clinic. In total, 529 out of...
We consider both Ab-secreting cell (ASC) and memory B cell (B Mem ) populations in a quantitative analysis of virus-specific B cell memory generated by intramuscular or intranasal vaccination of mice with inactivated influenza virus. After both forms of vaccination, the memory phase was characterized by localization of ASCs in the bone marrow and dispersion of B Mem to organized lymphoid...
A patient admitted to hospital for a supraclavicular painful mass. Ultrasonography showed soliter lymphadenopathy. He underwent H1N1 vaccination 1 week before this lymphadenopathy developed. Groosly the mass measured 1cm×0.8cm×0.8cm. It was round, yellow to brown, slightly soft. In pathologic examination, we detected edema in capsule of lymph node. The basic architecture was preserved. There was mottled...
This study describes the long-term complications in children with Haemophilus influenzae serotype b (Hib) vaccine failure and to determine their risk of other serious infections. The families of 323 children with invasive Hib disease after appropriate vaccination (i.e. vaccine failure) were contacted to complete a questionnaire relating to their health and 260 (80.5%) completed the questionnaire....
Incorporation of lipoamino acids (LAAs) into peptide structures effectively imparts self-adjuvanting activity onto otherwise ineffective immunogens. Our fully synthetic lipopeptide vaccine candidates against group A streptococcus (GAS) were composed of J14 as a target GAS B-cell epitope alongside a universal helper T-cell epitope (P25) and a LAA-based lipid moiety. In the current study, we investigated...
The mucosal vaccination is a non-invasive alternative approach for not only mucosal pathogens but also parenteral pathogens, since it induces both mucosal and systemic immunoreactions. The purpose of this study was to evaluate the application of intranasal (i.n.) immunization with a recombinant leishmanial protein against Leishmania infection. BALB/c mice were i.n. administered 1–3 times with Leish-111f...
Persistent immunity to hepatitis A and hepatitis B antibodies six years after vaccination of adolescents (aged 12–15 years) with a combined hepatitis A and B (HAB) vaccine following a 0, 6 month or a 0, 12 month schedule was assessed. Yearly (Year-2–6) serum samples were tested for anti-HAV and anti-HBs using EIA. Subjects with anti-HBs concentrations <10mIU/mL (14/23) at Year-5 or Year-6, received...
Here we demonstrated that bis-(3′,5′)-cyclic dimeric inosine monophosphate (c-di-IMP) exhibits potent adjuvant properties. BALB/c or C57BL/6 mice were immunized with the model antigens beta-galactosidase (β-Gal) or Ovalbumin (OVA) alone or co-administered with c-di-IMP by the intranasal route. Animals receiving c-di-IMP showed significantly higher anti-β-Gal or OVA immunoglobulin G titres (IgG) in...
Despite its high worldwide morbidity and mortality, there is yet no licensed vaccine for shigellosis. We reported the safety and immunogenicity of Shigella O-specific polysaccharide–protein conjugates in adults and young children and efficacy of Shigella sonnei conjugate in young adults.A double-blinded, randomized and vaccine-controlled Phase 3 evaluation of S. sonnei and Shigella flexneri 2a O-SP–rEPA...
In 2006, the heptavalent pneumococcal conjugate vaccine (PCV7) was introduced in the Norwegian Childhood Vaccination Programme in a 2+1 dose schedule; immunisations are administered at 3, 5 and 12 months. Changes in invasive pneumococcal disease in all ages from the baseline years 2004–2005 to 2008 were assessed, focusing on the indirect effect in the unvaccinated population.Following the introduction...
Maternal rubella status was compared between local residents with non-residents who delivered in our hospital during 1998–2008. Among the 60,822 women, non-immunity was more common in the non-residents (19.9% versus 8.1%, P<0.001). Significant difference and positive correlation with age and parity were found for both groups, but a significant inverse correlation with year-of-birth was found only...
A Phase 1 trial was conducted in malaria-naïve adults to evaluate the recombinant protein vaccine apical membrane antigen 1-Combination 1 (AMA1-C1) formulated in Montanide ® ISA 720 (SEPPIC, France), a water-in-oil adjuvant. Vaccinations were halted early due to a formulation issue unrelated to stability or potency. Twenty-four subjects (12 in each group) were enrolled and received 5 or 20μg...
The aim of the present study was to synthesise and screen a set of novel nicotine hapten immunogens used for the treatment of nicotine dependence. In the screening process we studied the amount of antibodies generated and their selectivity, using ELISA techniques, and their effects on nicotine-induced dopamine release in the NAC shell of the rat, assessed by in vivo voltammetry. We conclude...
