The Québec Immunization Program provides for the administration of a DTaP-HB-IPV-Hib vaccine at 2 months of age and at 4 months of age, followed by a DTaP-IPV-Hib vaccine at 1 year of age. To be fully protected against these diseases, a child must receive all the doses provided for in the regular immunization schedule.
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.
DTaP-HB-IPV-Hib vaccine and DTaP-IPV-Hib vaccine are safe. Most reactions are harmless and do not last long.
