Administration of multivalent influenza virus recombinant hemagglutinin vaccine in combination-adjuvant elicits broad reactivity beyond the vaccine components

Project description:Combining variant antigens into a multivalent vaccine is a traditional approach used to provide broad coverage against antigenically variable pathogens, such as polio, human papilloma and influenza viruses. However, strategies for increasing the breadth of antibody coverage beyond the vaccine are not well understood, but may provide more anticipatory protection. Influenza virus hemagglutinin (HA) is a prototypic variant antigen. Vaccines that induce HA-specific neutralizing antibodies lose efficacy as amino acid substitutions accumulate in neutralizing epitopes during influenza virus evolution. Here we studied the effect of a potent combination adjuvant (CpG/MPLA/squalene-in-water emulsion) on the breadth and maturation of the antibody response to a representative variant of HA subtypes H1, H5 and H7. Using HA protein microarrays and antigen-specific B cell labelling, we show when administered individually, each HA elicits a cross-reactive antibody profile for multiple variants within the same subtype and other closely-related subtypes (homosubtypic and heterosubtypic cross-reactivity, respectively). Despite a capacity for each subtype to induce heterosubtypic cross-reactivity, broader coverage was elicited by simply combining the subtypes into a multivalent vaccine. Importantly, multiplexing did not compromise antibody avidity or affinity maturation to the individual HA constituents. The use of adjuvants to increase the breadth of antibody coverage beyond the vaccine antigens may help future-proof vaccines against newly-emerging variants.

An inactivated multivalent influenza A virus vaccine is broadly protective in mice and ferrets [mouse]

Project description:Influenza A viruses (IAVs) present major public health threats from annual seasonal epidemics and pandemics as well as from viruses adapted to a variety of animals including poultry, pigs, and horses. Vaccines that broadly protect against all such IAVs, so-called “universal” influenza vaccines, do not currently exist, but are urgently needed. Here, we demonstrated that an inactivated, multivalent whole virus vaccine, delivered intramuscularly or intranasally, was broadly protective against challenges with multiple IAV hemagglutinin and neuraminidase subtypes in both mice and ferrets. The vaccine is comprised of four beta-propiolactone-inactivated low pathogenicity avian influenza A virus subtypes of H1N9, H3N8, H5N1, or H7N3. Vaccinated mice and ferrets demonstrated substantial protection against a variety of IAVs, including the 1918 H1N1 strain, the highly pathogenic avian H5N8 strain, and H7N9. We also observed protection against challenge with antigenically variable and heterosubtypic avian, swine, and human viruses. Compared to mock vaccinated animals, vaccinated mice and ferrets demonstrated marked reductions in viral titers, lung pathology, and host inflammatory responses. This vaccine approach indicates the feasibility of eliciting broad, heterosubtypic IAV protection and identifies a promising candidate for influenza vaccine clinical development.

Influenza peptide reactivity within a cohort of age-stratified individuals pre and post vaccination with the 2008/2009 trivalent influenza vaccine

Project description:The aim of the study was to test the hypothesis that peptide array reactivity will reveal patterns that can be associated with poor or effective neutralization response to seasonal influenza vaccine We diluted patient sera 1:80 and incubated dilutions on a streptavidin-coated glass surface that was printed with biotinylated peptides derived from seasonal strains of influenza hemagglutinin included in the 2008/2009 trivalent influenza vaccine In this study, serum from 76 study participants, subsetted into young (?30 years old) and elderly (?60 years old) categories were profiled for IgG/IgM antibody reactivity to influenza hemagglutinin peptudes. Using multivariate linear regression and correcting for multiple hypothesis testing by cross-validation, ee found that patterns of peptide reactivity associated with a poor or effective neutralization response to H1N1 and B strains of influenza.

Multivalent Influenza DNA vaccine induces cross-reactive polyfunctional T lymphocytes and promotes rapid clearance of heterologous challenge strain in non-human primates

Project description:Recent avian and swine-origin influenza virus outbreaks illustrate the ongoing threat of influenza pandemic. New vaccines that offer accelerated production and broader, more universal protection against drifted and shifted strains are needed. Here, we investigated a multivalent PMED DNA vaccine for the ability to induce antibody and T cell responses against four HA antigens, nucleoprotein and the ectodomain of M2 (M2e). Macaques in the Vaccinated and Control groups were intramuscularly anaesthetized with ketamine (10 mg/kg) and inoculated with a suspension containing 10^6.5 p.f.u. ml-1 of CA09 virus through a combination of intratracheal (4.5 ml), intranasal (0.5 ml per nostril), ocular (0.1 ml per eye) and oral (1 ml) routes (resulting in a total infectious dose of 10^7.4 PFU). Bronchoalveolar lavages were collected two weeks prior to challenge and at days 3, 7, and 10 post-infection. We performed microarray analysis on these samples.

Sequencing of the influenza PR8 virus hemagglutinin Sb site mutant library

Project description:Current flu vaccine induces strong response to plastic and higly variable hemagglutinin (HA) head. However, response to conserved epitopes in HA elicited by current vaccine or infection is very limited. We hypothesized that change the relative "molarity" of immunodominant epitopes and conserved domain might increase response to conserved domains. Therfore, we made a library with the most ommunodominant domian Sb site randomized and tested its efficacy in vivo. Here we show the diversity of the library.

Transcriptome signatures preceding the induction of anti-stalk antibodies elicited by a chimeric hemagglutinin-based universal influenza virus vaccine

Project description:A phase 1 clinical trial to test the immunogenicity of a chimeric group 1 HA (cHA) universal influenza virus vaccine targeting the conserved stalk domain of the hemagglutinin of influenza viruses was carried out. Vaccination with adjuvanted-inactivated vaccines induced high anti-stalk antibody titers. We sought to identify gene expression signatures that correlate with such induction. Messenger-RNA sequencing in whole blood was performed on peripheral blood of 53 vaccinees, at early and late time points after priming and boosting. We generated longitudinal data on peripheral blood of 53 volunteers, at early (days 3 and 7) and late (28 days) time points after priming and boosting with cHAs. Differentially expressed gene analysis showed no differences between placebo and live-attenuated vaccine groups. However, an upregulation of genes involved in innate immune responses and type I interferon signaling was found at day 3 after vaccination with inactivated adjuvanted formulations. Cell type deconvolution analysis revealed a significant enrichment for monocyte markers and different subsets of dendritic cells as mediators for optimal B cell responses and significant increase of anti-stalk antibodies in sera. A significant upregulation of immunoglobulin related genes was only observed after administration of adjuvanted vaccines (either as primer or booster) with specific induction of anti-stalk IGVH1-69. This approach informed of specific immune signatures that correlate with robust anti-stalk antibody responses, while also helping to understand regulation of gene expression induced by cHA proteins under different vaccine regimens.
