In 1900, for every 1,000 babies born in the United States, 100 would die before their first birthday, often due to infectious diseases. Today, vaccines exist for many viral and bacterial diseases. The National Childhood Vaccine Injury Act, passed in 1986, was intended to bolster vaccine research and development through the federal coordination of vaccine initiatives and to provide relief to vaccine manufacturers facing financial burdens. The legislation also intended to address concerns about the safety of vaccines by instituting a compensation program, setting up a passive surveillance system for vaccine adverse events, and by providing information to consumers. A key component of the legislation required the U.S. Department of Health and Human Services to collaborate with the Institute of Medicine to assess concerns about the safety of vaccines and potential adverse events, especially in children. Adverse Effects of Vaccines reviews the epidemiological, clinical, and biological evidence regarding adverse health events associated with specific vaccines covered by the National Vaccine Injury Compensation Program (VICP), including the varicella zoster vaccine, influenza vaccines, the hepatitis B vaccine, and the human papillomavirus vaccine, among others. For each possible adverse event, the report reviews peer-reviewed primary studies, summarizes their findings, and evaluates the epidemiological, clinical, and biological evidence. It finds that while no vaccine is 100 percent safe, very few adverse events are shown to be caused by vaccines. In addition, the evidence shows that vaccines do not cause several conditions. For example, the MMR vaccine is not associated with autism or childhood diabetes. Also, the DTaP vaccine is not associated with diabetes and the influenza vaccine given as a shot does not exacerbate asthma. Adverse Effects of Vaccines will be of special interest to the National Vaccine Program Office, the VICP, the Centers for Disease Control and Prevention, vaccine safety researchers and manufacturers, parents, caregivers, and health professionals in the private and public sectors.

Many potential applications of synthetic and systems biology are relevant to the challenges associated with the detection, surveillance, and responses to emerging and re-emerging infectious diseases. On March 14 and 15, 2011, the Institute of Medicine's (IOM's) Forum on Microbial Threats convened a public workshop in Washington, DC, to explore the current state of the science of synthetic biology, including its dependency on systems biology; discussed the different approaches that scientists are taking to engineer, or reengineer, biological systems; and discussed how the tools and approaches of synthetic and systems biology were being applied to mitigate the risks associated with emerging infectious diseases. The Science and Applications of Synthetic and Systems Biology is organized into sections as a topic-by-topic distillation of the presentations and discussions that took place at the workshop. Its purpose is to present information from relevant experience, to delineate a range of pivotal issues and their respective challenges, and to offer differing perspectives on the topic as discussed and described by the workshop participants. This report also includes a collection of individually authored papers and commentary.

The intricate ways in which they act, often with the exhibition of pleiotropic or synergistic effects, make the study of cytokine biology complicated, and the results potentially ambiguous using conventional systems. As a consequence, many investigators are now utilizing the powerful tools of transgenic technology to address some of these questions.

This casebook collects 64 case studies each of which raises an important and difficult ethical issue connected with planning, reviewing or conducting health-related research. The book's purpose is to contribute to thoughtful analysis of these issues by researchers and members of research ethics committees (REC's known in some places as ethical review committees or institutional review boards) particularly those involved with studies that are conducted or sponsored internationally. . This collection is envisioned principally as a tool to aid educational programs from short workshops on research.

Immunopotentiators in Modern Vaccines provides an in-depth insight and overview of a number of most promising immunopotentiators in modern vaccines. In contrast to existing books on the subject it provides recent data on the critical mechanisms governing the activity of vaccine adjuvants and delivery systems. Knowledge of immunological pathways and scenarios of the cells and molecules involved is described and depicted in comprehensive illustrations. Contributions from leading international authorities in the field Well-illustrated, informative figures present the interactions between immunopotentiators and the host immune system Each chapter lists advantages and potential hurdles for achieving a practical application for the specific immunopentiator

In chronic parasitic infections, the interplay between the host and the parasite suggests immuno-suppressive mechanisms developed by the parasite. Echinococcus granulosus, a tiny tapeworm that among other helminthes, favors the induction of T helper type 2 responses which are less severe and less destructive than T helper type 1 responses. This study aimed at exploring the immune response generated in BALB/c mice using genetic immunization technology. Immuno-modulation by the co-delivery of different cytokine genes (IFN-γ, IL-12, IL-4) was also investigated. Immunization by antigen B or its second subunit (EgAgB8/2) revealed dominated T helper type 2 cytokine response, IgG3 humoral response, low splenocyte cell proliferation, and low CD8+ cell count. However, restored CD8+ cell count, high splenocyte cell proliferation, and high expression of IFN-γ cytokine in IFN-γ gene co-immunized mice indicates the efficiency of cytokine gene immuno-modulation in skewing the response toward T helper type 1.

DNA-based vaccines represent a novel method of immunization that has been demonstrated to induce immune responses in animals against a variety of plasmid encoded antigens and following a number of different methods of vaccine delivery. We characterized the immune response to DNA-based vaccines encoding intracellular, membrane anchored (cell associated) and extracellular (secreted) forms of glycoprotein D (gD), an antigen from the viral envelope of the bovine herpesvirus-1 (BHV-1). Intramuscular injection of mice with plasmids encoding secreted or cell associated forms of this antigen led to seroconversion and a predominance of splenic IFN ã. Mice receiving plasmids encoding cell associated or secreted antigens displayed a predominance of IgG2a and IgG 1, respectively. The predominant serum isotype correlated with the cytokine and antibody isotype profiles within the draining lymph node. We demonstrated modulation of immune responses in mice following co-delivery of plasmids encoding a secreted form of gD and each of eight different murine cytokines (IL-1á, IL-12, IL-4, IL-6, IL-10, GM-CSF, IFN ã, TNF á). Plasmids encoding GM-CSF, TNF á, IL-4 and IL-6 demonstrated the capacity to enhance serum IgG titers and seroconversion efficiency. Plasmids encoding IFN ã and TNF á increased levels of serum IgG2a in mice. Varying the dose of plasmids encoding GM-CSF enhanced (10 [mu]g) or suppressed (50 [mu]g) serum antibody levels and induced significant increases in IL-4 levels in the spleen and draining lymph nodes. High doses of GM-CSF (50 [mu]g) increased the levels of serum IgG2a after boosting. Co-administration of plasmids encoding IFN ã either reduced (10 [mu]g) or enhanced (50 [mu]g) serum antibody levels and elevated mean serum IgG 2a levels. Finally, we investigated the potential for plasmids encoding the secreted form of gD to elicit immune responses in passively immune mice. We demonstrated that a single intramuscular immunization of passively immune C3H. HeN or C57BL.
