Book excerpt: This comprehensive volume compiles the concepts essential for the understanding of the pharmaceutical science and technology associated with the delivery of subunit vaccines. Twenty-one chapters are divided into four main parts: (I) Background; (2) Delivery Systems for Subunit Vaccines; (3) Delivery Routes, Devices and Dosage Forms; and (4) Pharmaceutical Analysis and Quality Control of Vaccines. Part one provide a basic background with respect to immunology and general vaccine classification. In part two, it presents representative types of vaccine delivery systems individually with focus on the physicochemical properties of the systems and their significance for the immune response they stimulate. These delivery systems include aluminum adjuvants, emulsions, liposomes, bilosomes, cubosomes/hexosomes, ISCOMs, virus-like particles, polymeric nano- and microparticles, gels, implants and cell-based delivery systems. Following these chapters, part three addresses the challenges associated with vaccine delivery via specific routes of administration—in particular subcutaneous, intramuscular, oral, nasal, pulmonary, transdermal and vaginal administration. Furthermore, the specific administration routes are discussed in combination with device technologies relevant for the respective routes as well as dosage forms appropriate for the device technology. Finally, the fourth part concerns pharmaceutical analysis and quality control of subunit vaccines.

Available in PDF, EPUB and Kindle. Book excerpt: Immunization is a powerful approach for the prevention and control of infectious disease, however despite the successes of modem vaccine development, there remain several notable obstacles for the advancement of vaccine-mediated improvements in global healthcare. Many of the current limitations in vaccine availability and administration are the result of obligate needle-based delivery, which in addition to contributing to reduced speed, ease, and compliance in administration, has been shown to contribute to reduced overall safety due to needle re-use and needle-based injuries. Needle-based vaccine delivery to immunologically passive tissues such as muscle may limit efficacy, thus motivating the targeting of more inherently potent immune-competent sites. These inherent limitations of needle-based vaccination on global health have led to a strong impetus to develop needle-free vaccination strategies which have the potential to improve vaccine efficacy and availability, enhance the ease, speed, and safety of vaccine administration, and reduce vaccination associated costs world-wide. Here we present the design and preclinical testing of several parallel materials strategies for the noninvasive delivery of subunit vaccines to the skin. We have utilized laser ablative micro-molding of poly(dimethylsiloxane) to generate bio resorbable poly(lactide-co-glycolide) micro-structured skin patches bearing -100 micron-scale needles arrayed across their surface. Upon topical application, these 'microneedle arrays' are able to safely, and painlessly insert into the immune-competent epidermal skin layers to generate microscopic conduits through which otherwise impermeant vaccines and therapeutics are able to passage into the body. We have leveraged this approach in combination with layer-by-layer (LbL) directed assembly to generate vaccine-loaded conformal coatings on the surface of these microneedle arrays, which are then delivered into the skin through topical patch application. The construction of coatings containing antigen-expressing plasmid DNA (pDNA), together with immune-stimulatory RNA, and degradable cationic polymers provided tunable control over vaccine dosage, rapid and effective vaccine delivery in murine and primate skin models, and potent immunogenicity against a model HIV antigen in mice. In this case, DNA vaccine delivery was able to elicit strong functional CD8' T cell and humoral responses matching or exceeding the potency of in vivo electroporation, currently the most promising approach for clinical DNA delivery in humans. Further efforts have explored the use of LbL for encapsulation and delivery of soluble and particulate protein subunit vaccines, giving enhanced generation of diverse and potent humoral responses in mice. In other work, we have developed an approach enabling rapid delivery of micron-scale degradable polymer matrices or hydrogel depots using dissolvable composite microneedle structures for the delivery of vaccines with programmable kinetics. These efforts have demonstrated the potential of persistent vaccine release on tuning immune potency following non-invasive microneedle delivery, including induction of potent effector and memory CD8* T cell responses and more powerful and diverse antigen-specific humoral responses. Finally, we have developed an approach for simple loading and delivery of clinically advanced recombinant adenoviral vaccine vectors from sugar-glass coatings on bioresorbable microneedles. Formulation in microneedle coatings improved vaccine stability at room temperature and preclinical testing of these vaccine patches in mice and nonhuman primates demonstrated equivalent immunogenicity compared to parenteral injection, eliciting strong systemic and disseminated mucosal CD8' and CD4* T cell responses to a model HIV antigen. These cellular responses were correlated with a similarly potent systemic and mucosal humoral response, together suggesting the utility of this approach for non-invasive adenoviral immunization in a model close to humans. Together these results strongly demonstrate the potential of materials engineering strategies for the effective formulation, delivery, and release of recombinant vaccines by microneedle patches targeting the skin. In addition to the significant practical advantages enabled by microneedle delivery including improved safety, convenience, and storage, we have shown that advanced formulation strategies paired with controlled release are able to initiate humoral and cellular adaptive immunity more potently than possible through parenteral injection. Comprehensive tests in both mice and primates have suggested that these principles may be broadly applied to enhance various recombinant vaccination strategies potentially targeting numerous disease targets. Finally, initial tests performed in nonhuman primates have indicated the promise of engineered microneedle approaches for successful translation to humans. Overall, these findings provide a strong basis for the continued development of similar vaccination strategies for the comprehensive transformation of conventional vaccination enabling significant vaccine-mediated improvements in global health.

Download or read book Mucosal Vaccines written by Pamela A. Kozlowski and published by Springer Science & Business Media. This book was released on 2012-01-13 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is focused on the development of vaccines which generate immune effectors capable of blocking mucosal entry or peripheral pathogen spread. A critical first step in the design of mucosal vaccines is the selection of administration route. Not all mucosal immunization routes are created equally when it comes to eliciting immune responses in multiple body compartments. This subject and situations when a mucosal route may not be required for vaccine delivery are reviewed here with an emphasis on the sublingual immunization route, which may offer a safer alternative to the nasal route for induction of broadly disseminated immune responses. External host defenses that inhibit entry of microorganisms at mucosal surfaces also pose obstacles to the efficient internalization of mucosally-applied vaccines. Transcutaneous immunization with appropriate adjuvants and permeation enhancers can induce mucosal immune responses and may be advantageous for bypassing these luminal barriers. Other chapters describe strategies for enhancing uptake of mucosal vaccines, for instance through targeted delivery to antigen-sampling M cells, construction of virus-like particles which mimic natural pathogens, addition of mucoadhesives or formulation as nanoparticles. Topics include edible vaccines as well as plant-based production of subunit or particulate vaccines that could be administered by any route. Dry powder vaccines that could be insufflated or directly applied to mucosal surfaces may be particularly ideal for mass vaccination in developing countries. The manufacture, stability and efficacy of powder formulations is comprehensively reviewed. We conclude with chapters on two of the greatest challenges facing mucosal vaccine development: human immunodeficiency virus and bioterrorist agents. This monograph highlights progress and information that should prove invaluable for the development of contemporary vaccines that prevent infection by these and other mucosal pathogens.

This book was released on 2011 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The skin is an ideal organ for the safe and convenient delivery of vaccines, small molecules, and other biologics. Members of the Irvine and Hammond groups have developed a polyelectrolyte multilayer thin film-coated microneedle platform that can achieve simultaneous DNA and nanoparticle delivery. This delivery platform has the advantage of direct delivery of DNA or polymer nanoparticles to immune-active cells at the interface between the dermis and epidermis, enhancing uptake of the delivered cargo by resident immune cells. Ideal for the delivery of DNA vaccines, this platform aims to bridge the gap in the lack of efficient delivery platforms hampering the effectiveness of DNA vaccines. The ability to co-deliver polymer nanoparticles can serve as a conduit for delivering immune stimulating adjuvants or other drugs for therapeutic applications. An overview of current vaccine and delivery system research is presented. Market factors for the commercialization of the polyelectrolyte multilayer thin film-coated microneedle delivery platform are considered along with the risk factors in bringing this invention to market. An assessment of the intellectual property surrounding the platform is performed and a preliminary market entry strategy is developed for minimizing the risks commercialization.

Download or read book Intradermal Immunization written by Marcel B.M. Teunissen and published by Springer Science & Business Media. This book was released on 2011-09-15 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of Current Topics in Microbiology and Immunology covers diverse topics related to intradermal immunization. The chapters highlight the effectiveness of intradermal immunization in experimental animal models or in clinical practice, all supporting the view that intradermal immunization is at least as good as other immunization routes. Keeping in mind that current vaccines are not specially designed for intradermal immunization, but show comparable efficiency even at reduced dosages, this underlines the great potential for the skin as a vaccination site. Hopefully, the overview in this volume will encourage vaccine designers to focus on this promising immunization route, and in addition, to inspire them to develop vaccines that are especially optimized for intradermal immunization.
