No you LITERALLY are.Nope. I disagree and many people much more versed in that scientific discipline feel the same.
1. Adenovirus gets its contents ripped out
2. Replaced with DNA coded to make mRNA
3. Adenovirus vaccine injected
4. Virus injects DNA into cells
5. DNA tells cell to make mRNA coded for the spike protein
6. Spike protein is made and hung on the outside of the cell
So instead of the mRNA getting injected the cell directly, you get injected with DNA that does *the exact same thing*
