Abstract:
Recent advances in antigen definition and production have made the development of a contraceptive vaccine more attainable. Such a vaccine must evoke an immune response that blocks an indispensable step in the reproductive process. Vaccine research involves many approaches to fertility prevention. Vaccines are being developed that could interrupt fertility by inhibition of gonadotrophin release, the function of follicle-stimulating hormone or the effects of human chorionic gonadotrophin (hCG); alternatively, they may prevent fertilization by interfering with the transport of spermatozoa or with sperm-zona pellucida binding. The most advanced prototype is a vaccine based on antibodies to beta hCG. Such vaccines are being studied for clinical efficacy. Many hurdles remain in contraceptive vaccine development. Since the antigens are peptides or small proteins, the resultant immune response is usually moderate, and better adjuvants and delivery systems must be developed to enhance and maintain the immune response. Improvement of the mucosal immune response may be necessary for vaccines incorporating sperm antigens. Research on vaccines that control fertility has resulted in a fascinating base of scientific knowledge that, it is hoped, can be converted into products that will allow another option for individuals who wish to control their fertility.

Abstract:
Despite advances in the development of new vaccines, there are still some diseases with no vaccine solutions. Therefore, further efforts are required to more comprehensively discern the different antigenic components of these microorganisms on a molecular level. This review summarizes advancement in the development of new carbohydrate-based vaccines. Following traditional vaccine counterparts, the carbohydrate-based vaccines introduced a new approach in fighting infectious diseases. Carbohydrates have played various roles in the development of carbohydrate-based vaccines, which are described in this review, including carbohydrates acting as antigens, carriers or targeting moieties. Carbohydrate-based vaccines against infectious diseases, such as group A streptococcus, meningococcal meningitis and human immunodeficiency virus, are also discussed. A number of carbohydrate- based vaccines, such as Pneumovax 23, Menveo and Pentacel, have been successfully marketed in the past few years and there is a promising standpoint for many more to come in the near future.

Abstract:
Salmonella enterica serovar Typhi (S. typhi) causes human typhoid fever, a serious and widespread disease in developing countries. Other Salmonella serovars are associated with food-borne infections. The recent emergence of multi-drug-resistant Salmonella strains highlights the need for better preventive measures, including vaccination. The available vaccines against Salmonella infection do not confer optimal protection. The design of new Salmonella vaccines must be based on the identification of suitable virulence genes and on knowledge of the immunological mechanisms of resistance to the disease. Control and clearance of a vaccine strain rely on the phagocyte oxidative burst, reactive nitrogen intermediates, inflammatory cytokines and CD4+ TCR-αβ+ T cells and are controlled by genes including NRAMP1 and MHC class II. Vaccine-induced resistance to reinfection requires the presence of Th1-type immunological memory and anti-Salmonella antibodies. The interaction between T and B cells is essential for the development of resistance following vaccination. The identification of immunodeficiencies that render individuals more susceptible to salmonellosis must be taken into consideration when designing and testing live attenuated Salmonella vaccines. An ideal live Salmonella vaccine should therefore be safe, regardless of the immunological status of the vaccinee, but still immunogenic.

Full text
Abstract:
Dengue virus (DENV) has become a global health threat with about half of the world’s population at risk of infection. Although the disease caused by DENV is self-limiting in the first infection, the antibody-dependent enhancement (ADE) effect increases the mortality in the second infection with a heterotypic virus. Since there is no specific efficient medicine in treatment, it is urgent to develop vaccines to prevent infection and disease progression. Currently, only a live attenuated vaccine, chimeric yellow fever 17D—tetravalent dengue vaccine (CYD-TDV), has been licensed for clinical use in some countries, and many candidate vaccines are still under research and development. This review discusses the progress, strengths, and weaknesses of the five types of vaccines including live attenuated vaccine, inactivated virus vaccine, recombinant subunit vaccine, viral vectored vaccine, and DNA vaccine.

Abstract:
In spite of the progress of conventional vaccines, improvements are required due to concerns about the low immunogenicity of the toxicity, instability, and the need for multiple administrations of the vaccines. To overcome the mentioned problems, nanotechnology has recently been incorporated into vaccine development. Nanotechnology increasingly plays an important role in vaccine development nanocarrier-based delivery systems that offer an opportunity to increase the cellular and humoral immune responses. The use of nanoparticles in vaccine formulations allows not only enhanced immunogenicity and stability of antigen, but also targeted delivery and slow release. Over the past decade, nanoscale size materials such as virus-like particles, liposomes, ISCOMs, polymeric, inorganic nanoparticles and emulsions have gained attention as potential delivery vehicles for vaccine antigens, which can both stabilize vaccine antigens and act as adjuvants. This advantage is attributable to the nanoscale particle size, which facilitates uptake by Antigen- Presenting Cells (APCs), then leading to efficient antigen recognition and presentation. Modifying the surfaces of nanoparticles with different targeting moieties permits the delivery of antigens to specific receptors on the cell surface, thereby stimulating selective and specific immune responses. This review provides an overview of recent advances in nanovaccinology.

Abstract:
Treating cancer with vaccines has been a challenging field of investigation since the 1950s. Over the years, the lack of effective active immunotherapies has led to the development of numerous novel strategies. However, the use of therapeutic cancer vaccines may be on the verge of becoming an effective modality. Recent phase II/III clinical trials have achieved hopeful results in terms of overall survival. Yet despite these encouraging successes, in general, very little is known about the basic immunological mechanisms involved in vaccine immunotherapy. Gaining a better understanding of the mechanisms that govern the specific immune responses (i.e., cytotoxic T lymphocytes, CD4 T helper cells, T regulatory cells, cells of innate immunity, tumor escape mechanisms) elicited by each of the various vaccine platforms should be a concern of cancer vaccine clinical trials, along with clinical benefits. This review focuses on current strategies employed by recent clinical trials of therapeutic cancer vaccines and analyzes them both clinically and immunologically.

Full text
Abstract:
Efforts to develop vaccines against Neisseria gonorrhoeae have become increasingly important, given the rising threat of gonococcal antimicrobial resistance (AMR). Recent data suggest vaccines for gonorrhoea are biologically feasible; in particular, epidemiological evidence shows that vaccines against a closely related pathogen, serogroup B Neisseria meningitidis outer membrane vesicle (OMV) vaccines, may reduce gonorrhoea incidence. Vaccine candidates using several approaches are currently in preclinical development, including meningococcal and gonococcal OMV vaccines, a lipooligosaccharide epitope and purified protein subunit vaccines. The Global STI Vaccine Roadmap provides action steps to build on this technical momentum and advance gonococcal vaccine development. Better quantifying the magnitude of gonorrhoea-associated disease burden, for outcomes like infertility, and modelling the predicted role of gonococcal vaccines in addressing AMR will be essential for building a full public health value proposition, which can justify investment and help with decision making about future vaccine policy and programs. Efforts are underway to gain consensus on gonorrhoea vaccine target populations, implementation strategies and other preferred product characteristics that would make these vaccines suitable for use in low- and middle-income, as well as high-income, contexts. Addressing these epidemiological, programmatic and policy considerations in parallel to advancing research and development, including direct assessment of the ability of meningococcal B OMV vaccines to prevent gonorrhoea, can help bring about the development of viable gonococcal vaccines.

Abstract:
La leishmaniose est une maladie tropicale négligée à transmission vectorielle qui est endémique dans 98 pays dont les plus pauvres. Vingt espèces de Leishmania sont capables d’établir une infection intracellulaire au sein des macrophages humains, provoquant différentes manifestations cliniques. Le développement d'un vaccin contre les leishmanioses est étayé par des preuves d'immunité naturelle contre l'infection, induite par une réponse à médiation cellulaire de type Th1 dominante associée à la production d'IFN-γ, d'IL-2 et de TNF-α par des cellules T polyfonctionnelles TCD4+ et TCD8+, conduisant à l'activation classique des macrophages entrainant la destruction des parasites. Induire une protection robuste et durable et déterminer les épitopes immunodominants responsables de la protection naturelle représente un véritable défi.Les protéines sécrétées sont des facteurs de virulence jouant un rôle important dans le cycle de vie des leishmanies et sont capables d’induire une protection durable chez le chien, un bon modèle pour l’infection humaine. Notre objectif est de développer, à partir du sécrétome de Leishmania, un vaccin de seconde génération reproductible et facile à produire à bas prix dans les zones d’endémie, avec des rendements de production rendant possible son utilisation à grande échelle.Les sécrétomes des six espèces les plus pathogènes de leishmanie (plus L. tarentolae) ont été analysés et comparées par spectrométrie de masse. Les antigènes candidats ont été recherchés dans l'ensemble des données disponibles (analyses protéomiques, littérature…). 52 antigènes candidats vaccin ont ainsi été sélectionnés, dont 28 avaient déjà été décrits et 24 sont nouveaux et découverts grâce à une approche de vaccinologie réverse.Une analyse de la prédiction de liaison des épitopes in silico HLA-I et –II a été réalisée sur tous les antigènes candidats vaccin, prenant ainsi en compte le polymorphisme HLA de la population mondiale. Pour sélectionner les meilleurs épitopes parmi des milliers d’épitopes potentiels, un script R automatisé a été développé en interne, selon des critères rationnels stricts. Ainsi, 50 épitopes de classe I et 24 épitopes de classe II ont été sélectionnés et synthétisés sous forme de peptides individuels. Des essais de toxicité in vitro ont montré l’absence de toxicité cellulaire de ces peptides.Les individus guéris par chimiothérapie généralement développent des réponses immunitaires protectrices à Leishmania. Des tests de stimulation des PBMC ont donc été réalisés avec des échantillons biologiques provenant de donneurs guéris de Tunisie et la production d'IFN-γ a été évaluée par ELISpot. De plus, il était important d'inclure dans l'étape de validation expérimentale des peptides des échantillons provenant d’individus naïfs, population cible à vacciner avec un vaccin prophylactique. Les résultats montrent que des peptides spécifiques de Leishmania induisent avec succès la production d'IFN-γ par les PBMC totaux provenant de donneurs guéris et par les lymphocytes T spécifiques amplifiés à partir du répertoire naïf.Globalement, la validation expérimentale des peptides réalisée exclusivement sur des échantillons humains nous fournira une base préclinique très solide pour développer un vaccin efficace capable de protéger les populations touchées par ces maladies. Elle constituera un moyen sûr et rentable de mieux sélectionner les candidats retenus pour le vaccin et d'éliminer ceux qui présentent un risque d'échec élevé au tout début du processus de développement du vaccin.Grâce à la combinaison de l'analyse protéomique et d'outils in silico, des candidats peptidiques prometteurs ont été rapidement identifiés pour le développement d'un vaccin. Le « pipeline » de développement préclinique du vaccin proposé fournit une sélection rapide de peptides immunogènes, offrant une approche puissante pour accélérer le déploiement d'un vaccin pan-spécifique efficace contre les leishmanioses
Leishmaniasis is a vector-borne neglected tropical disease endemic to 98 countries worldwide. Twenty Leishmania species are capable of establishing intracellular infection within human macrophages, causing different clinical presentations. Vaccine development against leishmaniases is supported by evidence of natural immunity against infection, mediated by a dominant cellular Th1 response and production of IFN-γ, IL-2 and TNF-α by polyfunctional TCD4+ and TCD8+ cells, ultimately leading to macrophage activation and parasite killing.Excreted-secreted proteins are important virulence factors present throughout Leishmania life stages and are able to induce durable protection in dogs, a good model for human infection. We aim to develop a second generation vaccine from the Leishmania secretome, with the potential for large scale dissemination in a cost-effective, reproducible approach.The secretome of six main pathogenic species (plus L. tarentolae) was analysed by Mass-Spectrometry and conserved candidate antigens were searched in the complete dataset. A total of 52 vaccine antigen candidates were selected, including 28 previously described vaccine candidates, and an additional 24 new candidates discovered through a reverse vaccinology approach.In silico HLA-I and –II epitope binding prediction analysis was performed on all selected vaccine antigens, with world coverage regarding HLA restriction. To select the best epitopes, an automated R script was developed in-house, according to strict rational criteria. From thousands of potential epitopes, the automated script, in combination with optimal IC50, homology to host and solubility properties, allowed us to select 50 class I and 24 class II epitopes, synthesized as individual peptides. In vitro toxicity assays showed these selected peptides are non-toxic to cells.The peptides’ immunogenicity was evaluated using immunoscreening assays with immune cells from human donors, allowing for the validation of in silico epitope predictions and selection, and the assessment of the peptide’s immunogenicity and prophylactic potential. Healed individuals, which had active infection and received treatment, possess Leishmania-specific memory responses and are resistant to reinfection, being considered the gold standard of protective immunity. On the other hand, the naive population is extremely important to include in the experimental validation step since it is the target population to vaccinate with a prophylactic vaccine. Importantly, a minimum specific T-cell precursor frequency is needed to induce long-lasting memory protective responses. Furthermore, there is also a positive correlation between immunodominant epitopes and a high frequency of specific T-cell precursors. Peptides able to induce Th1 and/or cytotoxic immune responses in both background are promising candidates for a vaccine formulation. Altogether,experimental validation exclusively in human samples will provide us a very strong base for a vaccine formulation and allow to accelerate translation to the field.Results show Leishmania-specific peptides successfully induce IFN-γ production by total PBMC from healed donors, and by specific T cells amplified from the naïve repertoire. Preliminary evidence exists for peptides which are immunogenic in both immune backgrounds (eight HLA-class I 9-mer peptides and five class II 15-mer peptides) which are, for now, the most promising candidates to advance for the multi-epitope peptide design.Through the combination of proteomic analysis and in silico tools, promising peptide candidates were swiftly identified and the secretome was further established as an optimal starting point for vaccine development. The proposed vaccine preclinical development pipeline delivered a rapid selection of immunogenic peptides, providing a powerful approach to fast-track the deployment of an effective pan-specific vaccine against Leishmaniases

Abstract:
This thesis describes work undertaken by the author at the University of Oxford. It begins by providing an introduction to malaria infection and pathophysiology, and a review of the latest attempts to produce an effective malaria vaccine. It goes on to describe the rationale behind the vaccines developed by the University of Oxford and others. A brief introduction to the process of planning and carrying out clinical trials of vaccines is then provided, and is followed by chapters describing two clinical trials, designed to test the safety, immunogenicity and then efficacy of candidate malaria vaccines. These trials were performed in Oxford, to examine two different vaccination approaches. The first intended to broaden the specificity of the vaccine induced immune response, by providing multiple antigens in one vaccine, aiming thereby to improve protection from malaria infection. The second regimen used a combination vaccine intending to induce both humoral and cellular immunity simultaneously, thereby providing enhanced efficacy against malaria infection. Neither approach was sufficient to provide protection from infection in the challenge studies described; however, some impact on the disease was detected in the second study. This is examined in detail. The laboratory work described studies background immune responses (both cellular and humoral) to vaccine antigens in a malaria exposed population, intended to support the inclusion of these antigens in the multi-antigen vaccine. The remaining chapters describe work in parasite life cycle modelling, undertaken to aid interpretation of results of these clinical trials, and finally an examination of the clinical course of malaria in the control volunteers who have taken part in the many challenge studies conducted in Oxford.

Abstract:
Vaccines have saved more lives than any other medical intervention. Recombinant vaccines provide unmatched safety profiles, but at the expense of reduced immunogenicity. Virus-like particles (VLPs) resemble viruses in size, shape and repetitive arrangement but are devoid of pathogenic genetic material and therefore safe. Poor immunogens can be rendered immunogenic by display on VLPs. Successfully decorating VLPs is still a major challenge. Genetic fusion or chemical modification is often time-consuming and can lead to misassembly or misfolding, which obstructs generation of the desired immune response. SpyCatcher is a genetically encodable protein, previously engineered to form a covalent isopeptide bond to its peptide-partner SpyTag. Presented in this thesis are SpyCatcher-VLPs, based on the fusion of SpyCatcher to the bacteriophage VLP AP205. SpyCatcher- VLPs can be conveniently conjugated with SpyTag fused antigens, simply by mixing. I demonstrate the modularity of this approach by covalently linking several complex, cysteine-rich malarial antigens to SpyCatcher-VLPs, such as the transmission-blocking antigen Pfs25 and the blood-stage antigen CIDR. A single administration of Pfs25-SpyTag conjugated to SpyCatcher-VLPs induced potent antibody generation against Pfs25, even in the absence of adjuvant. Anti-Pfs25 antibodies induced by this platform conveyed potent transmission-blocking activity in the mosquito vector. The thesis further demonstrates the feasibility of more complex Catcher-nanoparticle architectures. The previously engineered SnoopCatcher covalently reacts with SnoopTag peptide and is orthogonal to the SpyCatcher / SpyTag pair. IMX313 is an engineered chimera of the multimerization domain of chicken complement inhibitor C4-binding protein. This work describes fusion of SnoopCatcher and SpyCatcher to IMX313, which yields independently addressable Catcher-moieties on a single IMX313 nanoparticle. Display of two antigens on one particle may enable single-particle, multi-disease vaccines as well as multi-stage vaccines to tackle immune evasion of parasites. The platforms presented should accelerate and enhance vaccine development and may create opportunities for imaging and metabolic engineering.

Abstract:
Aeromonas hydrophila is an opportunistic pathogen that causes a wide range of symptoms and diseases in fish. Development of a commercial vaccine has been problematic due to the heterogenicity between isolates of A. hydrophila. A new approach using immunoproteomics was used in this study to try to develop a vaccine that would protect against a wide range of A. hydrophila strains. The virulence of 14 isolates of A. hydrophila from different geographical regions was determined in common carp (Cyprinus carpio) indicating that 6 isolates were virulent, while 8 isolates were avirulent. Expression of cellular and extracellular products (ECP) of six of these isolates (4 virulent and 2 avirulent isolates) were examined following culture of the bacterium in vitro, in tryptic soy broth, and in vivo, in dialysis tubing placed within the peritoneal cavity of carp. Two types of molecular weight cut off tubes (25 and 100 kDa) were used for the implants. Whole cell (WC), outer membrane protein (OMP) and ECPs of the bacteria grown in vitro and in vivo were analysed by 1 dimensional sodium dodecyl sulphate-polyacrylamide gel electrophoresis (1D SDS-PAGE). Additionally, 2D SDS-PAGE was used to analyse WC preparations of A. hydrophila grown in vitro and in vivo. The production of unique proteins and up and down-regulation of protein expression were observed in all the preparations of bacteria grown in vitro and in vivo. Unique bands were seen in the 1D SDS-PAGE at 58 and 55 kDa for WC and OMP preparations, respectively, for all the isolates cultured in vivo. Bands of increased intensity were observed at 70, 55, 50 and 25 kDa with WC preparations for the virulent isolates cultured in vivo. Analysis of WC preparations by 2D SDS-PAGE indicated differences in the expression of spots between bacteria cultured in vitro and in vivo. A number of unique spots, mostly between 30 and 80 kDa with pI values ranging from 5.0-6.0 were observed in the bacteria grown in vivo. The protein profiles of different preparations (WC, OMP, ECP) of bacteria cultured in vitro and in vivo were screened by 1D Western blot using antibodies from carp artificially infected with different isolates of A. hydrophila to identify potential vaccine candidates. The WC preparations of A. hydrophila (T4 isolate) grown in vitro were also analysed by 2D Western blot. A 50 kDa protein of A. hydrophila was found to be the most immunogenic molecule in both WC and OMP of bacteria grown both in vitro and in vivo. The protection efficacy of this protein was determined in goldfish by vaccinating fish with electro-eluted 50 kDa protein then challenging the fish with A. hydrophila. Fish were also passively immunised with fish sera raised to the 50 kDa protein and then challenged. The relative percentage survival (RPS) was 67 % in the vaccination trial, while the results were inconclusive for the passive immunisation trial. The 50 kDa protein was confirmed to be the S-layer protein of A. hydrophila following identification using matrix-assisted laser desorption ionisation time-of-flight mass spectrometry (MALDI-TOF MS). Recombinant S-layer protein was then produced and the cross-protection efficacy of this protein against six virulent isolates of A. hydrophila was confirmed in a large scale vaccination trial using carp. The RPS value for the 6 isolates of A. hydrophila ranged from between 56 and 87 %. The results of this project suggest that the immunogenic S-layer protein of A. hydrophila could be used as a common antigen to protect fish against infection by different isolates of this pathogenic bacterium.

Abstract:
Cervical cancer is the second most cancer in women worldwide with over 500000 new cases and 275000 deaths being registered every year. With nearly 73000 women dying every year, India now tops the world in cervical cancer deaths. India represents 26.4% of all women dying of cervical cancer globally. Cervical cancer estimated to be responsible for about 5% of human cancers worldwide. Currently available vaccines may not provide complete protection against all HPV types as the protection is primarily type specific. Furthermore, the available vaccines are delivered via intramuscular route and require three doses and require cold chain supply which increases the cost of vaccine. Therefore a single dose vaccine delivered via non-invasive route (nasal) that protects against multiple HPV types would be a cost effective and better alternative to the currently available HPV vaccines. The main objective of this study was to prepare HPV antigen loaded poly (lactic-co-glycolic acid) (PLGA) and Tri Methyl Chitosan (TMC) coated PLGA microparticles and compare their efficacy as nasal vaccine. The developed formulations were characterized for size, zeta potential, entrapment efficiency, mucin adsorption ability, in vitro and in vivo studies. PLGA microparticles demonstrated negative zeta potential whereas PLGA-TMC microparticles showed higher positive zeta potential. The protein loading efficiency was found as above 80%. Results indicated that PLGA-TMC microparticles demonstrated substantially higher mucin adsorption when compared to PLGA microparticles. HPV antigen encapsulated in PLGA-TMC particles elicited a significantly higher secretory (IgA) immune response compared to that encapsulated in PLGA particles. Present study demonstrates that PLGA-TMC microparticles with specific size range can be a better carrier adjuvant for nasal subunit vaccines. Surface modified PLGA microparticles proved great potential as a nasal delivery system for HPV infections where systemic and mucosal responses are necessary particularly in conditions after viral pathogens invade the host through the mucosal surface.

Abstract:
Abstract Biopharmaceutical community is devising modern techniques to boost the development, production, and distribution of COVID-19 vaccines in large scale with tremendous speed. This has shifted the focus towards smart manufacturing of vaccines through vaccine platforms. Vaccine platforms have great potential to rapidly generate new vaccines and can overcome the challenges of the traditional vaccine manufacturing approach without compromising on safety and efficacy. This preliminary study compares the traditional and modern vaccine manufacturing techniques, reviews COVID-19 vaccine manufacturing scenarios, and presents a framework to critique on the smartness of the novel platform-based COVID-19 vaccine development and manufacturing.

Abstract:
Vaccination is becoming one of the most important epidemic control measures in the post-pandemic era, and the pandemic has accelerated the development of various forms of COVID-19 vaccines. The inhaled vaccine has entered clinical trials as a more convenient form of vaccination. However, the nebulization equipment used in the experiments was not specifically designed for the public health care scenario of inhaled vaccine nebulization. It could not reflect the advantages and characteristics of the inhaled vaccine. This study is based on the scenario-based design theory to design practical application solutions for inhaled vaccine nebulization equipment. Methods: Using a scenario simulation experiment and semi-structured interviews we identified the behavioral requirements of medical staff in the inhaled vaccination scenario and invited expert participants to validate. Results: Based on interview analysis, 20 behavioral requirements and an inhaled vaccine medical staff persona were identified. Five optimized scenarios were designed according to scenario-based design theory. Scenarios were evaluated by expert participants, and the prototype was developed based on feedback. The prototype design concept focused on "optimizing human-machine interaction", "improving disposable inhaler design", and "optimizing vaccine reagent dosing process". Conclusion: The prototype was evaluated by experts to be effective and reasonable for practical application scenarios of the inhaled vaccine. Scenario-based design can be a useful tool for innovative product design in public medical service scenarios.

Abstract:
Vaccinomics, as one of the areas of personalized medicine, can increase the effectiveness of vaccines, including in epidemics. Nevertheless, it is accompanied by a cluster of bioethical issues. The article explores possible bioethical difficulties associated with the development of personalized vaccines: the matching of the research subject and the person receiving the vaccine; the problem of confidential genetic data; equitable distribution of medical resources.
