What are some of the safety issues associated with gene therapy? it usually has to be delivered using a carrier, called a vector. The most common gene therapy vectors are viruses because they can recognize certain cells and carry genetic material into the cells’ genes. Researchers remove the original disease-causing genes from the viruses, replacing them with the genes needed to stop disease. Unwanted immune system reaction, Targeting the wrong cells, Infection caused by the virus, Possibility of causing a tumo Do you believe that gene therapy is ethical? Why or why not? Its hard to say.
