If you have all the answers, why aren't you telling someone who can do something about it instead of playing keyboard warrior insulting other members on this site whose views you disagree with?
Otherwise, you're nothing more than a shill.

"Viral vectors are promising tools for gene therapy and vaccines"
gene therapies use viral vectors
J&J vaccine use viral vectors
The use the viral vector is used the same way in both cases. To deliver DNA into the nuclei of cells.
That is the whole point of a viral vector.
In the case of J&J vaccine the DNA delivered to the nuclei lacks other pathogen genes required for replication. (see link below)
"Gene therapy
Main article: Gene therapy
Gene therapy is a technique for correcting defective genes responsible for disease development. In the future, gene therapy may provide a way to cure genetic disorders, such as severe combined immunodeficiency, cystic fibrosis or even haemophilia A. Because these diseases result from mutations in the DNA sequence for specific genes, gene therapy trials have used viruses to deliver unmutated copies of these genes to the cells of the patient's body. There have been a huge number of laboratory successes with gene therapy. However, several problems of viral gene therapy must be overcome before it gains widespread use. Immune response to viruses not only impedes the delivery of genes to target cells but can cause severe complications for the patient. In one of the early gene therapy trials in 1999 this led to the death of Jesse Gelsinger, who was treated using an adenoviral vector.[2]
Some viral vectors, for instance gamma-retroviruses, insert their genomes at a seemingly random location on one of the host chromosomes, which can disturb the function of cellular genes and lead to cancer. In a severe combined immunodeficiency retroviral gene therapy trial conducted in 2002, four of the patients developed leukemia as a consequence of the treatment;[3] three of the patients recovered after chemotherapy.[4] Adeno-associated virus-based vectors are much safer in this respect as they always integrate at the same site in the human genome, with applications in various disorders, such as Alzheimer's disease. [5]
Vaccines
Main article: Viral vector vaccine
A live vector vaccine is a vaccine that uses an organism (typically virus or bacterium) that does not cause disease to transport the pathogen genes into the body in order to stimulate an immune response.[6] Viruses expressing pathogen proteins are currently being developed as vaccines against these pathogens, based on the same rationale as DNA vaccines. The genes used in such vaccines are usually antigen coding surface proteins from the pathogenic organism. They are then inserted into the genome of a non-pathogenic organism, where they are expressed on the organism's surface and can elicit an immune response.[clarification needed]
Unlike attenuated vaccines, viral vector vaccines lack other pathogen genes required for replication, so infection by the pathogen is impossible. Adenoviruses are being actively developed as vaccine vectors. "

" Adenoviruses
Adenoviruses are DNA viruses with broad cell tropism that can transiently transduce nearly any mammalian cell type. The adenovirus enters target cells by binding to the Coxsackie/Adenovirus receptor (CAR) (Bergelson et al.,1997). After binding to the CAR, the adenovirus is internalized via integrin-mediated endocytosis followed by active transport to the nucleus, where its DNA is expressed episomally (Hirata and Russell, 2000). Although adenoviral vectors work well for transient delivery in many cell types, for some difficult cell lines such as non-dividing cells and for stable expression, lentiviral vectors are preferred. The packaging capacity of adenoviruses is 7–8 kb."

"An adenovirus vaccine is a virus that has been altered so that it can't make you sick, it can't replicate, it cannot integrate into your DNA, so they take out some really important parts of that virus genome."

I don't know how I can spell it out more clearly for you. You are wrong.
