This vaccine side effects

Keep track of any and all side effects you have after receiving this vaccine. If you ever need to receive a booster dose, you will need to tell your doctor if the previous shot caused any side effects.

You should not receive a booster vaccine if you had a life threatening allergic reaction after the first shot.

Becoming infected with diphtheria, pertussis, or tetanus is much more dangerous to your health than receiving this vaccine. However, like any medicine, this vaccine can cause side effects but the risk of serious side effects is extremely low.

Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have any of these side effects within 7 days after receiving Tdap vaccine:

  • numbness, weakness, or tingling in your feet and legs;

  • problems with walking or coordination;

  • sudden pain in your arms or shoulders;

  • a light-headed feeling, like you might pass out;

  • vision problems, ringing in your ears;

  • seizure (black-out or convulsions); or

  • redness, swelling, bleeding, or severe pain where the shot was given.

Common side effects may include:

  • mild pain or tenderness where the shot was given;

  • headache or tiredness;

  • body aches; or

  • mild nausea, diarrhea, or vomiting.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report vaccine side effects to the US Department of Health and Human Services at 1-800-822-7967.
