Diphtheria, Tetanus and Pertussis (dTPa)
Posted on 22nd April, 2021
Diphtheria, Tetanus and Pertussis (whooping cough) are available as a trivalent vaccine with all three vaccines combined.
In WA, Pharmacists can administer the dTPa vaccine to adults and children over the age of 16 years old, with no prescription necessary. Infants receive dTPa as part of the National Immunisation Program, where doses are given at a very young age, through to ages 12 to 13 years old.
Booster doses may be required for the following people:
- Adults that have not had a booster dose in the last 10 years
- Those considered to be at high risk of infection
- Those at risk of spreading infection
- Pregnant women between week 20 and 32 of each pregnancy (* dose available for free via your GP)
Vaccination is recommended every pregnancy, as pertussis antibody levels reduce over time, and the dose can pass on some immunity to the newborn baby before their first dose is given at 2 months of age.
Close contacts (grandparents, fathers) and friends are considered at risk of spreading infection if they have not had a booster vaccine dose of dTPa within the last 10 years. Ideally, the dose should be received at least two weeks prior to close contact with the infant, to ensure full immunity.
Healthcare workers and early childcare workers are also considered to be those at risk of spreading the infection, and they should receive a booster dose of dTPa if they have not within the last 10 years.
