Available in PDF, EPUB and Kindle. Book excerpt: Why do we not have a vaccine for HIV? What are we doing wrong? Every HIV vaccine has failed so far, and public opinion is turning pessimistic against the scientific community. HIV vaccine efforts need a major shift in strategy. They require a better understanding of the immunological mechanisms that prevent African primates from getting AIDS. None of the 40 species of African primates, including chimpanzees and gorillas, get AIDS, even though all of them carry HIV-like viruses in their bodies. Why are they naturally vaccinated, while all of the man-made vaccines against HIV have failed miserably? This book offers intriguing new possibilities for the nature of human immunity, and the development of an effective AIDS vaccine. It is also a provocative treatise on the origin, evolution, and etiology of several forms of immune systems that is supported by a wealth of peer-reviewed scientific references. The compelling ideas presented in this study should have an important bearing on HIV vaccine development. It is a must read for anyone interested in the development of a safe AIDS vaccine, and for individuals interested in human immunity generally.

Download or read book Reassessing Twenty Years of Vaccine Development Against Tuberculosis written by Ulrich E. Schaible and published by Frontiers Media SA. This book was released on 2018-03-23 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tuberculosis (TB) remains the prime bacterial infection worldwide with 10.4 million infections and a death toll of 1.7 million people in 2016 according to WHO statistics. Tuberculosis is caused by members of the Mycobacterium tuberculosis complex, facultative intracellular bacteria able to thrive within otherwise potent innate defense cells, the macrophages. In a world of increasing numbers of infections with drug resistant M. tuberculosis strains, the daunting race between developing new therapeutics and emerging resistant strains will hardly produce a winner. This cycle can only be broken by enhancing population wide immune control through a better vaccine as the only one currently in use, M. bovis Bacillus Calmette Guerin (BCG). The protective efficacy of BCG against pulmonary tuberculosis in all age groups is dissatisfying and geographically highly diverse with the tropical areas showing the lowest efficacy rates. Despite worldwide vaccination coverage, the impact of BCG on the steep decrease of tuberculosis incidence rates in the developed world seems therefore questionable and can rather be attributed to improved social, housing and nutritional conditions, better health care, surveillance and treatment systems. The last 15 years saw tremendous efforts to improve vaccination strategies against tuberculosis. Different paths of vaccine approaches were followed including genetically improved BCG strains, attenuated M. tuberculosis variants, recombinant viral vectors and subunit vaccine candidates combined with novel more potent adjuvants. With the first novel vaccine candidates being evaluated in clinical phases II and III and initial results chastening the expectations, a critical reassessment of all candidates is inevitable. Here, we assembled experts to review and assess the current status of novel anti-tuberculosis vaccine candidates, their efficacy and prospects for implementation as well as the pitfalls and possible measures for improvement.

Download or read book Autism and Environmental Factors written by Omar Bagasra and published by John Wiley & Sons. This book was released on 2018-05-01 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explores environmental factors during fetal development that may contribute to autism It is well documented that in the majority of the cases, an autistic child's brain has acquired the genetic and organismal abnormalities that were initiated during the first trimester of their gestational period. Yet, scientists still don’t know what is causing these abnormalities; this book explains how the human brain develops and what the critical stages are in which a fetal brain may acquire genetic and developmental abnormalities. It presents scientific data supporting previous anecdotal observations to attempt to understand the complex puzzle that is autism. From chemical fragrances to herbicides, synthetic chemicals are abundant in everyday life and this book examines the evidence surrounding these chemicals and their effects, including on the developing human brain and how that might explain certain characteristics observed in autism. Discussing various aspects of potential ASD causing factors, Autism and Environmental Factors brings together as many pieces of the autism puzzle as possible in one place to begin to clarify the picture and spark discussion to ensure a safe environment for everyone, especially our developing children. Discusses the genetic and environmental factors that may contribute to autism Covers how the human brain develops and the critical stages in which a fetal brain may acquire genetic and developmental abnormalities Describes the rapid proliferation of synthetic chemicals in our modern world and the effects on the developing human brain—endocrine-disturbing chemicals that alter DNA, epigenetics, and hormones Written in a clear and accessible style Autism and Environmental Factors is an important book for researchers and students in neuroscience, neuroanatomy, developmental neurobiology and anyone focusing on autism research.
Download or read book Vaccine Design written by Michael F. Powell and published by Springer. This book was released on 2012-12-06 with total page 977 pages. Available in PDF, EPUB and Kindle. Book excerpt: When my interest was first drawn to the phenomenon of vaccination for virus diseases in the late 1930s, the state of the art and the science of vaccine design was not far advanced beyond the time of Jenner at the end of the 18th century and of Pasteur a century later. In the 1930s it was still believed that for the induction of immunity to a virus-caused disease the experience of infection was required, but not for a toxin-caused disease such as diphtheria or tetanus, for which a chemically detoxified antigen was effective for immu nization. This prompted the question as to whether it might be possible to produce a similar effect for virus diseases using nonreplicating antigens. When in the 1930s and 1940s it was found possible to propagate influenza viruses in the chick embryo, protective effects could be induced without the need to experience infection by the use of a sufficient dose of a noninfectious influenza virus preparation. Later in the 1940s, it became possible to propagate polio and other viruses in cultures of human and monkey tissue and to immunize against other virus diseases in the same way. Later, with the advent of the era of molecular biology and genetic engineering, antigens and vaccines could be produced in new and creative ways, using either replicating or nonreplicating forms of the appropriate antigens for inducing a dose-related protective state.
Download or read book The Childhood Immunization Schedule and Safety written by Institute of Medicine and published by National Academies Press. This book was released on 2013-04-27 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Immunization Safety Review written by Institute of Medicine and published by National Academies Press. This book was released on 2002-07-02 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: By two years of age, healthy infants in the United States can receive up to 20 vaccinations to protect against 11 diseases. Although most people know that vaccines effectively protect against serious infectious diseases, approximately one-quarter of parents in a recent survey believe that infants get more vaccines than are good for them, and that too many immunizations could overwhelm an infant's immune system. The Immunization Safety Review Committee reviewed the evidence regarding the hypothesis that multiple immunizations increase the risk for immune dysfunction. Specifically, the committee looked at evidence of potential biological mechanisms and at epidemiological evidence for or against causality related to risk for infections, the autoimmune disease type 1 diabetes, and allergic disorders.
Download or read book Small Clinical Trials written by Institute of Medicine and published by National Academies Press. This book was released on 2001-01-01 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
