Interpretation

An anti-Haemophilus influenzae type B (HIB) IgG antibody concentration of 0.15 mcg/L is generally accepted as the minimum level for protection at a given time; however, it does not confer long-term protection. A study from Finland suggested that the optimum protective level is 1.0 mcg/L postimmunization.(1) Furthermore, studies have shown that the response to HIB vaccine is age-related.
