The J&J vaccine is basically the same as a flu vaccine.

Not exactly. It's a viral vector - older than mRNA but not really proven either. What I liked about it is they used viral vector for things other than COVID (like Ebola vaccines). They have studied viral vector vaccines for other applications. (Of course, they're studying mRNA for a cancer vaccine, but the tech is much newer.)

Your seasonal flu shot is most commonly an inactivated virus vaccine, although if you've had the nasal spray flu vaccine, that's live attenuated.
