Development and application of genetically engineered viral vaccines of poultry

Recombinant DNA techniques may completely revolutionize the way vaccines are developed and used. They offer potentially purer, safer, and greater efficacy than many currently used vaccines. This paper describes the various current approaches being used to develop recombinant vaccines. Genes are being cloned into bacteria, yeast, viruses, and eukaryotic cells. Synthetic polypeptides of specific epitopes are also covered. Scientific, practical, economic, and government approval to use recombinant vaccines in the field is also discussed.
