In my experience (working for orgs with TNR since 2018), no one really has a blanket policy to re-trap cats with the intent just to vaccinate for Rabies. I personally do not follow up with Rabies vaccine for outdoor cats, unless they have a caretaker who really wants to and can help trap the cat(s). A cat who has already been trapped is (typically) a LOT harder to get in a trap again.
Luckily, a lot of recent studies on titer testings (blood testing for antibodies from vaccines) seem to show that Rabies vaccines are usually in their blood a lot longer than 1 year, anyways!
