- Kills 1 out of every 5 people who get it
What is diphtheria?

- Can lead to breathing problems, paralysis, heart failure, and death
- Kills 1 out of every 10 people who get it
What is pertussis (whooping cough)?

What if a needle is missed?
- You should 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, diphtheria and/or pertussis. These vaccines are required by law (Immunization of School Pupils Act, 2014) for school attendance. Students who are not vaccinated may be suspended from school.
Is Tdap 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.
