"Summary:Studies of vaccines derived from carbohydrate antigens have seen great progress. Synthetic carbohydrate-based vaccines, including polysaccharides, neoglycoproteins, and neoglycolipids, have been explored or used to prevent and treat bacterial and viral infections, cancer, and other diseases."

"This textbook provides an easy-to-understand introduction to the complex topic of vaccine research and development. It gives a comprehensive though clearly arranged insight to the most important aspects of molecular vaccinology, leading from the basics in immunology, to design of vaccines and mode of action of vaccines to the actual formulation, manufacturing and registration of vaccines. The volume is therefore a valuable text about modern vaccinology for graduate students and a basic introduction for newcomers in vaccine design and development."

"Development of vaccines : from discovery to clinical testing outlines the critical steps, and analytical tools and techniques, needed to take a vaccine from discovery through a successful clinical trial. Contributions from leading experts in the critical areas of vaccine expression, purification, formulation, pre-clinical testing and regulatory submissions make this book an authoritative collection of issues, challenges and solutions for progressing a biologic drug formulation from its early stage of discovery into its final clinical testing. A section with details and real-life experiences of toxicology testing and regulatory filing for vaccines is also included."

"Dalam upaya menginduksi kekebalan berspektrum luas yang responsif terhadap subtipe-subtipe HIV-1 yang berbeda, telah diteliti imunisasi vaksin DNA menggunakan vektor plasmid DNA dan virus fowlpox rekombinan dengan memanfaatkan gen-gen HIV-1 yang dirancang dari runutan konsensus turunan subtipe-subtipe HIV-1 di dunia yang mengekspresikan semua protein dari genom HIV-1 dengan peptida berukuran 30 asam amino yang overlapping dan tersusun secara acak (scrambled antigen vaccines, atau SAVINE).Tiga grup hewan coba yang terdiri dari masing-masing tujuh beruk (Macaca nemestrina) diimunisasi dengan regimen vaksin DNA standar dengan veklor plasmid DNA pHIS-64 dan vektor virus fowlpox rekombinan (rFPV) berbasis gen gag dan pol dan HIV-1 subtipe B, regimen vaksin DNA SAVINE dengan vektor pHIS-64 dan vektor rFPV berbasis genom HIV-1 yang diacak, serta vektor plasmid pHIS-64 dan FPV yang tidak mengandung gen sebagai grup kontrol. Respon kebal selular diamati dengan teknik ELiSpot dan pewamaan silokin intraselular, sedangkan respon kebal humoral diamati dengan teknik ELISA. Pada ketujuh hewan coba yang diimunisasi dengan vaksin DNA HIV-1 standar, secara umum hasil penelitian menunjukkan terinduksinya respon kebal selular terhadap protein Gag HIV-1 serta respon kebal humoral yang ditunjukkan dengan terdeteksinya antibodi terhadap protein p24 HIV-1. Respon kebal selular silang terhadap protein Gag HIV-1 dari subtipe yang berbeda juga ditunjukkan pada grup yang sama. Namun upaya melakukan imunisasi boosting ke-dua dengan vektor rFPV tidak menunjukkan perbaikan induksi respon kebal. Berbeda dari grup hewan coba yang menerima regimen vaksin DNA HIV-1 standar, pada grup yang menerima regimen vaksin DNA HIV-1 SAVINE secara umum tidak menunjukkan adanya induksi respon kebal, kecuali pada satu ekor hewan yang menunjukkan respon kebal selular yang lebih luas terhadap protein Pol dan protein-protein lain HIV-1 meski pada tingkat induksi yang amat rendah. Pengembangan teknologi vaksin SAVINE terus diperbaiki dan disempumakan dengan kemungkinan melibatkan vektor virus aktif yang lain sehingga induksi respon kebal yang diharapkan bisa tercapai.

T cell immunity plays a critical role in controlling HIV-1 viremia, and encoding a limited set of HIV-1 genes within DNA and poxvirus vectors can, when used sequentially, induce high levels of T cell immunity in primates. However, a limited breadth of T cell immunity exposes the host to potential infection with either genetically diverse HIV-1 strains or T cell escape variants of HIV-1. In an attempt to induce maximally broad immunity, we examined DNA (prime) and recombinant Fowlpox virus (rFPV, boost) vaccines encoding all HIV-1 genes derived from a global HIV-1 consensus sequence, but expressed as multiple overlapping scrambled 30 amino acid segments (scrambled antigen vaccines, or SAVINEs).Three groups of 7 pigtail macaques (Macaca nemestrina) were immunized with sets of DNA and rFPV expressing Gag/Pol antigens only, the whole genome SAVINE antigens, or no HIV-1 antigens. T cell immunity was monitored by ELISpot and intracellular cytokine staining, while the humoral immune response was monitored by p24 antibody capture ELISA. High levels of cross-subtype HIV-specific T cell immunity to Gag were consistently induced in the 7 macaques primed with DNA and rFPV vaccines expressing Gag/Poi as intact proteins. The humoral immunity was also induced in the animals from the same group. It was however, difficult to repeatedly boost immunity with further rFPV immunizations, presumably reflecting high levels of anti-FPV immunity. Unfortunately, this vaccine study did not consistently achieve a broadened level of T cell immunity to multiple HIV genes utilizing the novel whole-virus SAVINE approach, with only one of 7 immunized animals generating broad T cell immunity to multiple HIV-1 proteins. Further refinements are planned with alternate vector strategies to evaluate the potential of the SAVINE technology."

"The aim of this book is to provide an overview of some of the technology platforms that have been realized or are currently under development to try to address unsolved and new issues in the field of vaccine development."
