Tetanus, Diphtheria, Pertussis (Tdap)

The Tdap vaccine protects against three diseases in one needle: tetanus, diphtheria and pertussis.
• Routinely given to teenagers at 14-16 years of age as a booster to the immunizations they received as a child.
• All adults should receive one dose of Tdap if they have not had one in adulthood. This should replace one of their Td boosters of which are due for every 10 years.
• All pregnant women in every pregnancy, ideally from 27 – 32 weeks gestation, but can be given anytime from 13 weeks up until delivery. Getting the vaccine while pregnant provides protection for the newborn during the first 2 months of life (when they are at highest risk).

When given on the recommended schedule:

• 99% of those fully vaccinated are protected against tetanus.
• 97-100% of those fully vaccinated are protected against diphtheria.
• 85-90% of those fully vaccinated are protected against pertussis.

• At this time there are no other ways to prevent these diseases.
• Hand washing and covering the mouth and nose while coughing/sneezing can help reduce the spread of disease.
• The risk of a serious reaction or side effect from this vaccine is much less than the risk of tetanus, diphtheria or pertussis.
• If you experience any side effect worse than what is listed below, please seek medical advice and notify the health unit.
