Combined diphtheria, tetanus, pertussis (whooping cough), and polio vaccine (DTaP-IPV) – Under 4 years of age


Vaccination is the best protection against these diseases and their complications:

The DTap-IPV vaccine is given to babies and children under 4 years of age who need protection against these 4 diseases.

For children over 4 years of age and adults, another combined diphtheria, tetanus, pertussis and polio vaccine is available. To find out more about this other vaccine, go to the page Combined diphtheria, tetanus, pertussis (whooping cough) and polio vaccine (Tdap-IPV) – 4 years of age and older.


Some symptoms may be caused by the vaccine, e.g. redness at the injection site. Other problems may occur by chance and are not related to the vaccine, e.g. cold, gastro, headache.
