got the J&J single shot in May 2021. mainly as a work requirement. i had mild sick/flu symptoms and a sore arm for a day. funny that my job made it a requirement since I've been WFH since March 2020. they were planning to go back in the office but every time they started getting ready to, another variant/wave came through lol.
but I went to Hawaii in August and they required the shot for entry. my wife got the shot (also J&J single shot) 14 days before the trip and pretty much only for the trip, she didnt have any reaction. Looks like they've dropped the requirements as of March 26th now for US residents.
We don't have plans to get a booster. neither of us have work requirements for it and we live in a low-risk area and COVID has been on a strong downward/cooling/waning trend. I'd pretty much only get it if my work required it, but I doubt they will since no one seems to care about COVID anymore lol.
I haven't exactly been attending super-spreader events, but I also haven't been hiding in my basement in fear. just living my life and wearing a mask where required

but even those mask rules are largely lifted in my area.
my whole family has been vaxxed (moderna or pfizer), and many of them even got a booster. they've all got COVID at least once. and my super woke double masking double vaxxing sister-in-law got it twice lol. Me and my wife have yet to get it and we've even hung out with them when they had
that lol
