That's me.
Wife and I got covid about 6 months after the vax. At the time, 6 months was thought to perhaps be the limit of the Moderna and Pfizer versions' effectiveness, though no one really knew. And as my medical wife is always wont to tell me, there's so many factors in play that it's not as simple as "how long does it last?" even if years of data have been piled up. Turns out the body is super complicated. Who knew. (fyi, the vax may have helped you, even if you didn't get the virus until a year later. Or it may not have helped you. There's no solid answer on that and anybody who says otherwise is fooling themselves.)
Anyway, we did more than fine but we'll never know how much was benefit of the vax and how much was just we're sort of young and have no exacerbating risk factors mixed with our immune systems' natural response.
At the time I felt like we had pretty good reasons to get it when it came out, largely having to do with for our patient's sake since we're in close contact with elderly people with conditions so much. We thought we were reducing their chances of getting infected by us, and in a way that was probably true. Never got any boosters, tho, and don't plan on it.
I'll tell you this--I'd be lying if I said it didn't make me nervous at the time. It was offered to medical personnel first, probably for that very reason, and because I'm a pencil pusher who works at a clinic I qualify as medical personnel. So we got it just as it was coming out, before anybody in our area. Me not being the medical brain my boss or my wife is, I was very apprehensive about it and I basically did it because they had kept on top of the developments and felt confident in the safety of the vaccines. If not for their comfortability with it I doubt I'd have ever gotten vax'd.
