This is vaccine that works in way that is taught in our SDA education systems high school biology class. Thinking that the vaccine destroys or modifies DNA is the equivalent of saying kissing and holding hands can make you pregnant.
You are talking about changing DNA which is in the core of a cell. The vaccine only works in the cytoplasm of the cell and is not capable of reaching the DNA. Physically impossible. How do we know, well science, we have learned about the rules that God created and biology follows without fail.
I would advise you refresh your knowledge of basic biology.
