What does your canning reference say? I've always read that you can re-do a jar with a failed seal within 24 hours. But honestly, I can often use my hands to open jars with the single-use, BPA-coated metal lids. I don't worry about the estrogenics because the lids aren't in contact with the food once they're removed from the water bath, and I don't worry about the seal since the vacuum is preserved (the lid is "down"). I wouldn't consider your situation a failed seal at all.
