TDVAX (Td)

Diphtheria and tetanus are serious diseases caused by bacteria.

Diphtheria can lead to breathing problems, paralysis, heart failure, or death.

Tetanus (lockjaw) causes painful muscle tightening, which can result in the jaw "locking" so the person cannot open their mouth, swallow, or breathe. Tetanus can lead to death.

Diphtheria spreads from person to person. Tetanus enters the body through a cut or wound.

The tetanus and diphtheria vaccine (also called Td) is used to help prevent these diseases. This vaccine helps your body build immunity to the disease but will not treat an active infection you already have.

Td vaccine is for adults and children who are at least 7 years old.

Like any vaccine, the Td vaccine may not protect every person from disease.

Becoming infected with tetanus or diphtheria is much more harmful to your health than getting this vaccine.

You should not get this vaccine if you have ever had a severe allergic reaction to a diphtheria or tetanus vaccine or any ingredient in the vaccine.

Tell your vaccination provider if you have or have ever had:

• an allergy to latex;
• an allergic reaction;
• severe pain or swelling after receiving a vaccine that contains tetanus;
• Guillain-Barré syndrome (within 6 weeks after receiving the vaccine); or
• a weak immune system (caused by disease, certain medicine, chemotherapy, or radiation).

If you are pregnant or breastfeeding, your doctor or vaccination provider should decide if you need a Td vaccine.

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

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

Keep track of all side effects you have. If you need a booster dose, you must inform the vaccination provider if the previous shot caused any side effects.

Becoming infected with tetanus or diphtheria 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 low.

TDVAX may cause serious side effects. Call your doctor immediately if you have:

• severe pain, swelling, or redness where the shot was given;
• severe dizziness or fainting; or
• nervous system problems—numbness, pain, tingling, weakness, burning or prickly feeling, vision or hearing problems, trouble breathing.

Common side effects include:

• redness, pain, or swelling where the shot was given;
• joint pain, muscle weakness; or
• headache, feeling unwell.

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.

This vaccine is given as an injection (shot) into a muscle.

This vaccine is usually given as a series of 3 shots. The timing of the shots depends on which Td vaccine you receive. Follow your vaccination provider's schedule.

A booster shot is also recommended in children who are 11 or 12 years old, and again every 10 years throughout adulthood.

If it has been longer than 5 years since your last booster, you may need an emergency booster shot if you have been exposed to tetanus through a skin wound.

Be sure to receive all recommended doses of this vaccine or you may not be fully protected against disease. Follow your doctor's instructions or the schedule recommended by your local health department.

Contact your vaccination provider if you miss a booster dose or if you fall behind schedule. The next dose should be given as soon as possible. There is no need to start over.

An overdose of this vaccine is unlikely to happen.

Follow your doctor's instructions regarding any limits on food, drinks, or activities.

Before you get this vaccine, tell your vaccination provider about any other vaccines you have had recently.

Also, inform the vaccination provider if you have recently taken any drugs or treatments that can weaken your immune system, such as:

• steroids;
• medicines for psoriasis, rheumatoid arthritis, or other autoimmune disorders; or
• medicines for cancer or to prevent organ transplant rejection.

If you are taking any of these medications, you might not be able to receive the vaccine, or you may need to wait until you finish the other treatments.

This list is not complete. Other drugs may affect TDVAX, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here.
