A genetically modified virus is a virus that has been altered or generated using biotechnology methods, and remains capable of infection.Genetic modification involves the directed insertion, deletion, artificial synthesis or change of nucleotide bases in viral genomes.
A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques.The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or natural recombination".

The most commonly used gammaretroviral vector is a modified Moloney murine leukemia virus (MMLV), able to transduce various mammalian cell types. MMLV vectors have been associated with some cases of carcinogenesis. [26] Gammaretroviral vectors have been successfully applied to ex vivo hematopoietic stem cell to treat multiple genetic diseases.

Viral immunotherapy is the use of virus to stimulate the body's immune system. Unlike traditional vaccines, in which attenuated or killed virus/bacteria is used to generate an immune response, viral immunotherapy uses genetically engineered viruses to present a specific antigen to the immune system. That antigen could be from any species of ...
Live recombinant vaccines are biological preparations that stimulate immune responses to a pathogen through the use of genetically modified live bacteria or viruses.These live pathogens are biologically engineered to express exogenous antigens in the cytoplasm of target cells, thereby triggering immune responses. [1]
Genetically modified organisms refers to any plant, animal or microorganism that has been genetically altered, due to modern biotechnology like genetic engineering. Often, GMOs are labeled “GE ...
Genetically modified viruses can be used as viral vectors to transfer target genes to another organism in gene therapy. [44] First the virulent genes are removed from the virus and the target genes are inserted instead. The sequences that allow the virus to insert the genes into the host organism must be left intact.
A company called Oxitec is planning on expanding its genetically-engineered mosquito project to try and rid areas in Brazil of the virus. Scientists are trying to use genetically engineered ...
