Abstract

We analyzed eight invasive Haemophilus influenzae strains isolated from individual children vaccinated appropriately for their ages. Five of the strains were type b and three were nontypeable strains. Children infected with nontypeable strains had a protective level of anti-H. influenzae type b antibodies, while only one of the children whose cases represented true vaccine failure did.
