Follow-up Question

Thank you!!

a. What specific type of VECTOR will you use to perform your gene therapy? Please select from the following list of potential vectors: disabled retrovirus, adenovirus, adeno-associated virus (AAV), or herpes simplex virus (HSV), then give two reasons why this specific vector is the most appropriate for your gene therapy. Please explain why you were able to rule out the other potential vectors. NOTE: you MUST select a vector that is appropriate for this specific disorder and gene.   

b. What are two specific drawbacks, disadvantages, or risks associated with using this type of vector.
