My doctor tells me that the shots are good for 10 years. I only get one every 10 years so you should be fine unless your doc gives some generic shot. You'll be okay, don't panic.Well crud, I called the doctor and they said my last tetanus shot was in 2017. I feel like I called a few years ago and asked because I had gotten cut and they had told me it was more recent than that, but I must have misremembered.
So now I'm in the urgent care waiting to get a booster, ugh. I'll be paranoid about tetanus now.
