Vaccination is the best protection against serious Hib infections and their complications.

Hib vaccine is given before the age of 5. It is usually combined with the diphtheria, whooping cough, tetanus, hepatitis B, and poliomyelitis vaccines. This vaccine is also given to persons, irrespective of their age, who have a medical condition that increases their risk of serious Hib infection.


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.

Hib vaccine is safe. Most reactions are harmless and do not last long.
