Tetanus diphtheria (Td) Vaccine

PDF/Printer Friendly Version

Getting vaccinated is the best way to protect against some very serious infections. The Canadian Paediatric Society and the National Advisory Committee on Immunization strongly recommends routine immunization. Tetanus, diphtheria (Td) vaccine is a two-in-one needle. It protects against diphtheria and tetanus. It is recommended for use in persons seven years of age and older.

What is Tetanus? Diphtheria?

Tetanus or lockjaw is a serious disease that can happen if dirt with the tetanus germ gets into a cut in the skin. Tetanus germs are found in everything, usually in soil, dust, and manure. It does not spread from person to person. Tetanus causes cramping of the muscles in the neck, arms, legs and stomach, and painful convulsions which can be severe enough to break bones. Even with early treatment, tetanus kills two out of every 10 people who get it.

Diphtheria is a serious disease of the nose, throat and skin. It causes sore throat, fever and chills. It can be complicated by breathing problems, heart failure and nerve damage. Diphtheria kills one out of every 10 people who get the disease. It is passed to others through coughing and sneezing.

How well does the vaccine protect my child?

When the vaccine is given in the recommended number of shots, it protects over 95% of recipients against tetanus, over 85% against diphtheria. Vaccination also makes these diseases milder for those who may catch them.

When should Td vaccine be given?

Most people get vaccinated against tetanus and diphtheria in early childhood with a booster given every 10 years thereafter.

Is the vaccine safe?

Yes. Mild pain, swelling and redness for a few days are common at the spot where the needle was given. A few people may get a mild fever, lose their appetite or feel tired for a day or two after the needle. The benefits of this vaccine are much greater than the risks associated with getting the diseases. There is no risk of a pregnant women or anyone else catching any disease from a person who has been vaccinated recently.

Who should not get the vaccine?

Td vaccine should not be given under the following conditions:

  • High fever or serious infection worse than a cold
  • Serious allergic reaction (anaphylaxis) to previous doses of this vaccine
  • Severe allergy to any component of the vaccine
  • Pregnancy- consult with primary health care provider
  • Diagnosis of Guillain-Barre syndrome occurring within 8 weeks of receiving vaccine containing tetanus toxoid
  • Blood clotting problems after receiving diphtheria and/or tetanus vaccine

What should I do if serious side effects do occur?

Depending on urgency, you should go to your doctor/health care provider or nearest emergency department if any of the following symptoms develop within three days of getting the needle:

  • Hives
  • Swelling of the mouth and throat
  • Trouble breathing, hoarseness or wheezing
  • High fever (over 39ºC or 103ºF)
  • Convulsions or seizures
  • Other serious reactions to the vaccine
