Haemophilus influenzae in Ireland
Haemophilus influenzae is a bacterium that can cause serious infection in humans, particularly in children, but also in individuals with weakened immune systems.
There are a number of strains of H. influenzae. Strains are classified as those with capsules (capsular types) and those without capsules (non-encapsulated types). Six capsular types (a-f) are recognized.
A polysaccharide conjugate vaccine against type b (Hib) infections was introduced in Ireland in September 1992. In 2006 a Hib booster dose was introduced into infant schedule in the second year of life.
