> they are a more traditional "standard" vaccination (adenovirus vector)

Are viral vectored vaccines “more traditional” and “standard”? They’re relatively new too aren’t they?

It’s a genetically engineered virus that injects its DNA into the cell nucleus which instructs the cell DNA to produce mRNA that instructs the cell to produce virus spike proteins.

By comparison, mRNA vaccines at least skip the cell nucleus step and inject mRNA directly into the outer cytoplasm, no need to interact with the DNA in the nucleus.

It seems the only really traditional and standard vaccines are the inactivated virus ones like Sino that inject dead viral material. Those are the type we’ve been using for decades.
