Same here. Me and my son. No mRNA and no issues.
Likewise, I had the J&J in the early days. No adverse reactions (no reaction at all), but I got the “I’ve been vaxxed” certification which turned out handy in many subsequent situations. I avoided the mRNA shots like the plague.
Personally I think the J&J was probably deprecated because The Powers That Be, corrupt and greedy, wanted all the revenue for themselves. The J&J shot was less experimental, much less expensive, etc. and didn’t provide as much grease to the palms of our evil overlords.
Sic transit.
