Abstract
The COVID-19 pandemic placed the field of vaccinology squarely at the center of global consciousness, emphasizing the vital role of vaccines as transformative public health tools. The impact of vaccines was recently acknowledged by the award of the 2023 Nobel Prize in Physiology or Medicine to Katalin Kariko and Drew Weissman for their seminal contributions to the development of mRNA vaccines. Here, we provide a historic perspective on the key innovations that led to the development of some 27 licensed vaccines over the past two centuries and recent advances that promise to transform vaccines in the future. Technological revolutions such as reverse vaccinology, synthetic biology, and structure-based design transformed decades of vaccine failures into successful vaccines against meningococcus B and respiratory syncytial virus (RSV). Likewise, the speed and flexibility of mRNA vaccines profoundly altered vaccine development, and the advancement of novel adjuvants promises to revolutionize our ability to tune immunity. Here, we highlight exciting new advances in the field of systems immunology that are transforming our mechanistic understanding of the human immune response to vaccines and how to predict and manipulate them. Additionally, we discuss major immunological challenges such as learning how to stimulate durable protective immune response in humans.

Abstract
Cross-presentation (XPT) is an adaptation of the cellular process in which dendritic cells (DCs) present exogenous antigens on major histocompatibility complex (MHC) class I molecules for recognition of the cytotoxic T lymphocytes (CTL) and natural killer (NK) cells, resulting in immunity or tolerance. Recent advances in DCs have broadened our understanding of the underlying mechanisms of XPT and strengthened their application in tumor immunotherapy. In this review, we summarized the known mechanisms of XPT, including the receptor-mediated internalization of exogenous antigens, endosome escape, engagement of the other XPT-related proteins, and adjuvants, which significantly enhance the XPT capacity of DCs. Consequently, various strategies to enhance XPT can be adopted and optimized to improve outcomes of DC-based therapy.

Abstract
Meningococcal disease by serogroup B has been a public health problem in Brazil in the last decades. The Brazilian Oswaldo Cruz Foundation has been working to develop a vaccine with detergent-treated outer membrane vesicles (OMV) and detoxified endotoxin (dLOS) from Neisseria meningitidis serogroup B prevalent strains. A phase I study, enrolling 26 adults (18–44 years of age) was performed using experimental vaccines combining B components and aluminum hydroxide as adjuvant. It was a dose escalation study testing vaccines made of 25, 50, and 100 µg OMV protein/mL (sum of both strains) and dLOS in half amount of total protein concentration, with three doses given two months apart. Adverse events were mild/moderate with frequency increasing with the amount of antigens. Pain in the site of injection was the most frequent reaction in all doses, reported in more than the 85% across vaccine groups. Considering all injections, cephalea was the most common systemic adverse event, detected in 11.1%, 17.2% and 32.1%, respectively with doses of 12.5 μg, 25 μg and 50 μg. High titers of total IgG (ELISA) were observed for the vaccine components before vaccination. Protective levels of bactericidal antibodies (titer ≥1:4) for both vaccine strains were also present. Considering a 4-fold increase of IgG titers compared to pre-immune values (seroconversion), 50%-70% of those who received intermediate and highest doses of antigens presented satisfactory response for OMV of N44/89 strain. The lowest dose vaccine induced no seroconversion for strain N44/89, and 11% for strain N603/95. For the three vaccines doses, 25% of seroconversion, in total IgG against LOS, was observed. Increased antibody bactericidal activity was observed for both strains in higher antigen concentrations. For IgG against LOS, all vaccine formulations showed 25% of seroconversion. In conclusion, MenB-Bio experimental vaccines were well tolerated and immunogenic, thus allowing phase II studies.

Abstract
Advances in material science have set the stage for nanoparticle-based research with potent applications for the diagnosis, bioimaging, and precise treatment of diseases. Despite the wide range of biomaterials developed, the rational design of biomaterials with predictable bioactivity and safety remains a critical challenge. In recent years, the field of cell-membrane-based therapeutics has emerged as a promising platform for addressing unmet medical needs. The utilization of natural cell membranes endows biomaterials with a remarkable ability to serve as biointerfaces that interact with the host environment. To improve the function and efficacy of cell-membrane-based therapeutics, a series of novel strategies is developed as cell-membrane-display nanotechnology, which utilizes various methods to selectively display therapeutic molecules of cell membranes on nanoparticles. Although cell-membrane-display nanotechnology remains in the early phases, considerable work is currently being conducted in the field. This review discusses details of innovative strategies for displaying cell-membrane molecules, including the following: 1) displaying molecules of cell membranes on biomaterials, 2) pretreating cell membranes to induce increased expression of inherent molecules of cell membranes and enhance their function, and 3) inserting additional functional molecules on cell membranes. For each area, the theoretical basis, application scenarios, and potential development are highlighted.

Abstract
BACKGROUND Neisseria meningitidis serogroup B (MenB) is the most frequent cause of invasive meningococcal disease (IMD) in Spain. The multicomponent vaccine against MenB (4CMenB) was approved in Spain in January 2014. METHODS We present 4 cases of children who developed MenB-associated IMD despite previous vaccination with 4CMenB. Extensive immunologic diagnostic work-up was performed in order to rule out any immunodeficiency. Also, molecular characterization of the MenB strain was conducted to determine whether bacterial antigens matched vaccine antigens. RESULTS Among the 4 patients (2 girls), 2 had previous risk factors for IMD (recurrent bacterial meningitis of unknown origin and treatment with eculizumab). All patients developed meningitis, but only 2 developed septic shock; they were all cured without sequelae. No other primary or secondary immunodeficiencies were detected. MenB sequence type 213 was identified in 3 cases. With the exception of neisserial heparin-binding antigen peptide 465 present in 1 isolate, the rest of the isolated strains harbored vaccine antigen variants that did not match antigen variants included in the vaccine. CONCLUSIONS We present 4 children who developed MenB-associated IMD despite previous vaccination with 4CMenB. In 2 cases, the antibodies induced by 4CMenB likely were not effective against the isolated strains. A high level of suspicion for IMD seems advisable regardless of the patient's vaccination history.

Abstract
Background The 4-component capsular group B meningococcal vaccine (4CMenB) was licensed as a 4-dose infant schedule but introduced into the United Kingdom as 3 doses at 2, 4, and 12 months of age. We describe the immunogenicity and reactogenicity of the 2 + 1 schedule in infants. Methods Infants were randomized to receive 4CMenB with routine immunizations (test group) at 2, 4, and 12 months or 4CMenB alone at 6, 8, and 13 months of age (control group). Serum bactericidal antibody (SBA) assay against a serogroup B meningococcal reference strain (44/76-SL), memory B-cell responses to factor H binding protein, Neisseria adhesion protein A, Neisseria heparin binding antigen, Porin A (PorA), and reactogenicity was measured. Results One hundred eighty-seven infants were randomized (test group: 94; control group: 93). In the test group, 4CMenB induced SBA titers above the putative protective threshold (1:4) after primary and booster doses in 97% of participants. Postbooster, the SBA GMT (72.1; 95% confidence interval [CI], 51.7-100.4) was numerically higher than the serum bactericidal antibody geometric mean titre (SBA GMT) determined post-primary vaccination (48.6; 95% CI, 37.2-63.4). After primary immunizations, memory B-cell responses did not change when compared with baseline controls, but frequencies significantly increased after booster. Higher frequency of local and systemic adverse reactions was associated with 4CMenB. Conclusions A reduced schedule of 4CMenB was immunogenic and established immunological memory after booster.

Outer membrane vesicles engineered to express membrane-bound antigen program dendritic cells for cross-presentation to CD8 + T cells. Acta Biomater 2019; 91:248-257.

Abstract
Outer membrane vesicles (OMVs) are vesicular nano-particles produced by Gram-negative bacteria that are recently being explored as vaccine vector. The fact that OMVs can be efficiently produced by a hypervesiculating Salmonella typhimurium strain, are packed with naturally-occurring adjuvants like lipopolysaccharides (LPS), and can be engineered to express any antigen of choice, makes them ideal candidates for vaccinology. However, it is unclear whether OMVs induce dendritic cell (DC)-mediated antigen-specific T cell responses and how immune activation is coordinated. Here, we show that OMVs induce maturation of human monocyte-derived DCs, murine bone marrow-derived DCs and CD11c+ splenic DCs. OMV-induced DC maturation was dependent on the presence of LPS and the myeloid differentiation primary response 88 (MyD88) adapter protein downstream of toll-like receptor signaling. Importantly, OMVs did not induce pyroptosis/cell death, but instead provided a significant survival benefit in DCs over non-stimulated DCs. OMVs displaying a sizeable ovalbumin fragment at the vesicle surface induce potent cross-presentation in BMDCs and splenic CD11c+ DCs to OTI CD8+ T cells, dependent on MyD88. Interestingly, the OMV-induced preference to cross-presentation was only partly dependent on the BATF3-dependent CD8a+ professional cross-presenting DC subset. Hence, an OMV-specific programming of DCs that induces maturation and provides a survival benefit for antigen presentation to T cells is identified. Additionally, for the first time, antigen-specific and potent cross-presentation of antigen-loaded OMVs to CD8+ T cells is demonstrated. These data provide mechanistical insight into the processes needed for the DC-mediated cross-presentation of OMV-derived antigens to CD8+ T cells with implications for therapeutic strategies. STATEMENT OF SIGNIFICANCE: Bacteria are primarily known to cause disease. However, recent research has focused on using engineered bacteria and its byproducts as vaccine agents. In particular, outer membrane vesicles (OMVs) have shown promise in eliciting potent immunity against a variety of pathogens. While most vaccines rely on the generation of antibodies, the control of viral replication and tumor growth is driven by cytotoxic CD8+ T cells induced by dendritic cells (DCs). As such, there is a dire need for vaccines that use DCs to elicit CD8+ T cell responses. Studying OMVs as engineered biomaterial and its interaction with DCs allows tailored induction of immunity. This study includes important findings on OMV-dendritic cell interactions and for the first time supports OMVs as vehicles for the induction of antigen-specific CD8+ T cell responses. Additionally, important mechanistical insight into the molecular pathways needed for the cross-presentation of OMV-derived antigens to CD8+ T cells is provided.

Abstract
BACKGROUND In February 2015, two unlinked culture-confirmed cases of Neisseria meningitidis serogroup B (MenB) disease occurred at a local college in Rhode Island ("college X") within 3 days. This represented a 489-fold increase in the incidence of MenB disease, and an outbreak was declared. For the first time, bivalent rLP2086 (Trumenba) was selected as a mandatory intervention response. A mass vaccination clinic was coordinated, which provided a unique opportunity to collect safety data in a real-world population of college-age participants. Though the Advisory Committee on Immunization Practices recommends MenB vaccination for college-age individuals (16-23 year olds), there is limited quantifiable safety data available for this population. METHODS The Dillman total design survey method was used. Adverse events of bivalent rLP2086 were solicited and quantified retrospectively 2-4 months following each dose of vaccine. Safety data from six clinical trials were used as comparison tools. RESULTS The most commonly reported adverse event following vaccination was injection site pain. Reported rates of injection site pain, fatigue, myalgia, fever, and chills were similar than those reported in clinical trials. Reported rates of headache were lower than in clinical trials. CONCLUSIONS This study is the first to examine adverse events of bivalent rLP2086 in a real-world setting where more than 90% of a college-age population was vaccinated.

Abstract
The majority of invasive meningococcal disease (IMD) in the developed world is caused by capsular group B Neisseria meningitidis, however success with vaccination against organisms bearing this capsule has previously been restricted to control of geographically limited clonal outbreaks. As we enter a new era, with the first routine program underway to control endemic group B meningococcal disease for infants in the UK, it is timely to review the key landmarks in group B vaccine development, and discuss the issues determining whether control of endemic group B disease will be achieved. Evidence of a reduction in carriage acquisition of invasive group B meningococcal strains, after vaccination among adolescents, is imperative if routine immunization is to drive population control of disease beyond those who are vaccinated (i.e. through herd immunity). The need for multiple doses to generate a sufficiently protective response and reactogenicity remain significant problems with the new generation of vaccines. Despite these limitations, early data from the UK indicate that new group B meningococcal vaccines have the potential to have a major impact on meningococcal disease, and to provide new insight into how we might do better in the future.

Abstract
While vaccines have decreased the burden of disease, many adolescents still remain under-immunized, particularly for human papillomavirus (HPV) and influenza. We review the most current data regarding adolescent immunizations in the United States and discuss proven strategies that work for increasing vaccination rates. Strategies that have been shown to improve rates include provider feedback, immunization information systems (or registries), and enhanced access outside of provider offices, such as school-based immunization programs. Overall, practices may want to consider multimodal quality improvement approaches to enhance practice vaccination rates. The public health and cost benefits of immunizing adolescents are well known, yet recent measles outbreaks in the United States have highlighted issues with state immunization laws and vaccine refusals. Providers should be clear in their advice regarding vaccines and use effective reminder strategies as parents commonly cite not having enough information or knowledge that a vaccine was needed for their adolescent. Additional research is needed regarding adolescent consent for vaccines, as well as adolescent and parental refusal, in order to design systems that will help inform families and allow for widespread vaccine availability.

Abstract
Neisseria meningitidis causes severe invasive meningococcal diseases (IMDs) in humans including meningitis and septicemia, responsible for serious clinical conditions and leading to life-long disabilities and death. Serogroup B dominates IMDs burden in Italy, accounting for over 60% of total cases. On January 2013 the European Medicine Agency (EMA) licensed the first serogroup B meningococcal (MenB) vaccine in Europe. A number of European countries and Regions have introduced the new MenB vaccine in their immunization schedule, including Italy. In this paper we present the state of art, related critical issues and future perspectives of MenB vaccine introduction in Italy, in the context of the most recent available epidemiological data. In particular, we systematically assess the ongoing processes in the 8 Italian regions and one autonomous province that have already introduced MenB vaccine. With the new 2014-2018 National Vaccine Prevention Plan including active MenB vaccine offer about to be adopted, it is of fundamental importance to gather further evidence on MenB vaccine clinical effectiveness, duration of protection and cost-effectiveness. Italian regions are called to organize and manage MenB immunization programs. Careful consideration will need to be devoted on timing, doses, and co-administration with other vaccines but also to economic assessments and strengthened communication to the general public. Our data will help to plan, implement and evaluate MenB immunization programmes in other Italian and international settings.
