Introduction of new procedures and new products realized through Genetic Engineering will have a profound effect on public health, agriculture and food industries. Treatment will genetically engineered enzymes that lower cholesterol or saturated fatti acids, can have a great impact on cardio-vascular diseases. Genetic Engineering in itself is not a discipline but a powerful tool. Biocompatible pesticides and herbicides can be made through Genetic Engineering to keep the environment clean. Genetic screening becomes obligatory for employment, life insurance acceptance would have questionable social implications. The development of human and animal proteins will open new vistas for diagnosis and therapy. Vaccines remain one of the best approaches to control infections diseases. Bacterial, viral, fungal, amoebal and trypanosomes are the major causative agents. A successful experiment has been established by the eradication of small pox globally in 1977.
The recombinant live vaccines are particularly promising in their wide applicability and possibility of combining multiple antigenes. The use of manipulated somatic cells in the therapy of genetic diseases is imminent. Beneficial modifications of the germline of domestic animals is a distinct possibility.
