I think the standard recommendation for adults is every ten years, and then if you get a questionable puncture they'll have you get another if your last was >5 years (even if it was <10) but they're also safe to get more often, like they recommend pregnant women get it during every pregnancy (bc if you get it at the right time, you pass some of the pertussis immunity to the fetus)
Wisconsin has a state db, too, and it's set up in a way that's pretty easy for people to look up their own records; some other states that have databases make you jump through a lot of hoops to get your own info and others have databases with no public access. I assume some states may not have a statewide db at all but I can't tell you one off the top of my head since I mostly deal with WI immunizations.
I've had to submit a bunch of stuff to them lately, if our patients got their COVID vaccine(s) out of state, we're entering it into our EMR as usual but we've also been submitting it to the WIR since that's one they're more likely to need to be able to reference and it's nice to have it all in one spot.
