You or your child might experience pain, redness or swelling at the injection site. Some people develop a mild fever after getting the shot. Others experience headache, tiredness, nausea or diarrhea. It's not as common, but some people have experienced chills, body aches, sore joints, rash or swollen glands after getting their tetanus shots.
If you have a severe reaction after getting a tetanus shot, such as a severe allergy, coma or seizures, it's not recommended that you get another tetanus shot, unless your reaction wasn't related to the shot.
Also, children with minor illnesses, such as a cold, may be vaccinated, but children who are moderately or severely ill should usually wait until they recover before getting the DTaP vaccine.
What's the follow-up?
Public health officials recommend that you get a tetanus shot every 10 years. If you have an accident, such as stepping on a rusty nail, you should get a tetanus shot, even if you've gotten a shot within the past 10 years. This is recommended because the vaccine's effectiveness can wane over time.
