Do tetanus vaccines have side effects?

The tetanus vaccine may, of course, show side effects, but most of them do not show up and the side effects are generally mild. Related side effects are mainly redness, pain or itching at the injection site. Systemic symptoms may show mild fever, which is likely to be accompanied by tiredness, fatigue, headache and other uncomfortable manifestations. In fact, the systemic symptoms are similar to a small cold. The symptoms of a cold are relatively mild, so the adverse reactions caused by tetanus vaccine generally disappear quickly, and the symptoms are generally not too obvious. Therefore, tetanus vaccine has side effects, but the side effects are relatively mild. Of course, it may also show more serious side effects, but serious side effects are even more rare, such as obvious bleeding allergies or even anaphylactic shock. Therefore, patients should be observed for 30 minutes after tetanus vaccination.
