Carbohydrate-Based Vaccines


Book Description

The past three decades have witnessed the development and regulatory approval of glycoconjugate vaccines against several medically important bacterial pathogens, including Haemophilus influenzae type b, Streptococcus pneumoniae, Neisseria meningitides, and Salmonella typhi. Immunologic protection against these and many other bacterial diseases is mediated through opsonophagocytic antibodies directed against the surface carbohydrates that define the bacterial serogroup or serotype and serve as virulence factors. These vaccines are composed of bacterial capsular polysaccharides chemically conjugated to immunogenic carrier proteins. Given that the diseases caused by these bacterial pathogens are most pronounced in infants and young children, the development of the glycoconjugate vaccine technology has had a considerable impact on public health. Many of the chapters in this volume were assembled as a follow-up from a symposium entitled "Carbohydrate-Based Vaccines and Adjuvants" which took place at the 254th American Chemical Society National Meeting held in Washington, DC (August 2017). The symposium was sponsored by Pfizer and the Carbohydrate (CARB) and Biotechnology (BIOT) divisions. This book, therefore, reflects the importance of this field toward design, development, manufacture and licensure of the complex carbohydrate-based (glycoconjugate) vaccines. The book has been organized into thirteen chapters, which cover a comprehensive landscape including the clinical history, design, development, chemistry, manufacturing and control (CMC) aspects, pre-clinical assays, adjuvants and the various approaches used to develop carbohydrate-based vaccines.




Vaccine Design

This volume provides a practical guide providing step-by-step methods and protocols on vaccine development and production. Divided into three volumes, Volume 3: Resources for Vaccine Development guides readers through chapters on vaccine adjuvants, vaccine vectors, production, vaccine delivery systems, vaccine bioinformatics, vaccine regulation, and intellectual property. Written in the format of the highly successful Methods in Molecular Biology series, each chapter includes an introduction to the topic, lists necessary materials and reagents, includes tips on troubleshooting and known pitfalls, and step-by-step, readily reproducible protocols. Authoritative and practical, Vaccine Design: Methods and Protocols, Second Edition, Volume 3: Resources for Vaccine Development aims to be a useful practical guide to researchers to help further their study in this field.

Small Clinical Trials


Book Description

Clinical trials are used to elucidate the most appropriate preventive, diagnostic, or treatment options for individuals with a given medical condition. Perhaps the most essential feature of a clinical trial is that it aims to use results based on a limited sample of research participants to see if the intervention is safe and effective or if it is comparable to a comparison treatment. Sample size is a crucial component of any clinical trial. A trial with a small number of research participants is more prone to variability and carries a considerable risk of failing to demonstrate the effectiveness of a given intervention when one really is present. This may occur in phase I (safety and pharmacologic profiles), II (pilot efficacy evaluation), and III (extensive assessment of safety and efficacy) trials. Although phase I and II studies may have smaller sample sizes, they usually have adequate statistical power, which is the committee's definition of a "large" trial. Sometimes a trial with eight participants may have adequate statistical power, statistical power being the probability of rejecting the null hypothesis when the hypothesis is false. Small Clinical Trials assesses the current methodologies and the appropriate situations for the conduct of clinical trials with small sample sizes. This report assesses the published literature on various strategies such as (1) meta-analysis to combine disparate information from several studies including Bayesian techniques as in the confidence profile method and (2) other alternatives such as assessing therapeutic results in a single treated population (e.g., astronauts) by sequentially measuring whether the intervention is falling above or below a preestablished probability outcome range and meeting predesigned specifications as opposed to incremental improvement.

The Childhood Immunization Schedule and Safety


Book Description

Vaccines are among the most safe and effective public health interventions to prevent serious disease and death. Because of the success of vaccines, most Americans today have no firsthand experience with such devastating illnesses as polio or diphtheria. Health care providers who vaccinate young children follow a schedule prepared by the U.S. Advisory Committee on Immunization Practices. Under the current schedule, children younger than six may receive as many as 24 immunizations by their second birthday. New vaccines undergo rigorous testing prior to receiving FDA approval; however, like all medicines and medical interventions, vaccines carry some risk. Driven largely by concerns about potential side effects, there has been a shift in some parents' attitudes toward the child immunization schedule. The Childhood Immunization Schedule and Safety identifies research approaches, methodologies, and study designs that could address questions about the safety of the current schedule. This report is the most comprehensive examination of the immunization schedule to date. The IOM authoring committee uncovered no evidence of major safety concerns associated with adherence to the childhood immunization schedule. Should signals arise that there may be need for investigation, however, the report offers a framework for conducting safety research using existing or new data collection systems.




Carbohydrate-based Vaccines


Book Description

This book is the first of its kind entirely dedicated to carbohydrate vaccines written by renowned scientists with expertise in carbohydrate chemistry and immunochemistry. It covers the synthesis of carbohydrate antigens related to bacteria and parasites such as: Heamophilus influenza, Streptococcus pnemoniae, Shigella flexneri, Candida albicans, Mycobacterium tuberculosis, and Chlamydia. The first three chapters are of wide interest as they cover fundamental concerns in new vaccine developments. The first one presents the immune system and how carbohydrate antigens are processed before protective antibodies are produced. It also illustrates antigen presentation in the context of major histocompatibility complexes (MHCs). The second chapter describes regulatory issues when carbohydrate vaccines are involved while the third one discuss several techniques used in conjugation chemistry and the implication of certain chemical linkages that may induce unexpected anti-linker antibodies. This section will be particularly appealing for those involved in drug-conjugate design, pro-drug developments, and drug vectorization. The book concludes with one chapter that illustrates the principle through which peptide antigens can functionally mimic carbohydrate epitopes, thus, unraveling the potential for peptide surrogates as replacement for complex carbohydrate structures. This book is unique in that it covers all aspects related to carbohydrate vaccines including the success story with the first semi-synthetic bacterial polysaccharide vaccine against Heamophilus influenza type b responsible for pneumonia and meningitis, liable for more than 600,000 infant deaths worldwide in developing countries. The book also presents regulatory issues and will thus be vital for government agencies approving candidate vaccines. It widely covers synthetic methodologies for the attachment of carbohydrate antigens to peptides and immunogenic protein carriers. Vaccines against bacterial antigens, cancer, and parasites are also discussed by worldwide experts in this field in details. No other book contains such a wide panel of different expertise. It will also be useful to students and researchers involved with the immunology of forreings antigens and how the under appreciated carbohydrate antigens are processed by the immune system.
