Td Vaccine

Td Adsorbed®

This two-in-one vaccination protects against tetanus and diphtheria. These diseases are easily prevented with vaccination.

What is tetanus (lockjaw)?

  • Caused by a germ that can be found anywhere, but usually in dirt, dust and feces (poop)
  • Tetanus enters the body through cuts, scratches, or wounds
  • Is not spread person to person
  • Causes painful muscle cramping and muscle spasms
  • Kills 1 out of every 5 people who get it

What is diphtheria?

  • An infection caused by a germ that spreads to other by coughing and sneezing
  • Symptoms include sore throat, fever, difficulty swallowing, and loss of appetite
  • Can lead to breathing problems, paralysis, heart failure, and death
  • Kills 1 out of every 10 people who get it

Who should get Td vaccine?

  • Adults who have already had a tetanus, diphtheria and acellular pertussis (Tdap) vaccine during adulthood and have not had a booster shot in the past 10 years
  • Based on a doctor’s judgment, a Td booster may be needed if the last Td containing vaccine was given more than 5 years ago and a person gets an injury that could lead to tetanus

Talk to your doctor/public health nurse if you:

  • Had a bad reaction to a vaccine or an ingredient in the vaccine, or have any other allergies
  • Are pregnant
  • Take medications or have any diseases that lower the immune system or increase bleeding
  • Feel very sick

What if a needle is missed?

  • Get the next needle as soon as possible
  • If you didn’t follow the routine immunization schedule a “catch-up” schedule will be recommended

What if I decide not to be immunized?

Choosing not to be immunized or delaying immunization puts you/your child at risk of getting sick with tetanus and/or diphtheria.

Is Td vaccine safe?

Yes! You may have no reaction or mild symptoms that include:

  • Redness, swelling,  and pain where the needle went in
  • Low fever
  • Children may become fussy or sleepier than usual;

These normal reactions usually last between 12 and 24 hours.

When should I call my doctor?

Serious reactions after vaccination are very rare.  Get immediate medical help if you/your child have any unusual symptoms such as:

  • trouble breathing, swelling in your face/mouth and/or blotchy skin (hives)
  • fever above 40°C (104°F);
  • crying or fussing for more than 24 hours;
  • worsening swelling, redness, and/or pain where the needle went in;
  • unusual sleepiness (difficult to wake)

You know best.  If you notice anything that is not normal after a vaccination, check with your healthcare provider.

Talk to your healthcare provider if you have any questions.


  • Make sure to update your immunization record
  • Notify the Health Unit each time your child receives a vaccine by phone (519-753-4937 ext. 451) or online
