Hib vaccine coverage in children attending day care/nursery school in East York.

This survey assessed Haemophilus influenzae b vaccine coverage and factors affecting compliance in children at increased risk. A telephone survey was conducted of a random sample of 75 children, aged 24-60 months, attending licensed day care/nursery schools in East York. 96% of the sample was surveyed; only 51% were vaccinated. Older children were less likely to be immunized and there were more single-parent families among the non-vaccinated. The age, educational level and country of birth of the parents and the number of siblings were not associated with vaccination status. In 20% of the non-vaccinated group, concern about side effects was the main reason for non-compliance. For 91%, a factor of "moderate/very much concern" was the perceived unimportance of preventing Haemophilus influenzae b illness. Education for parents and physicians, special programs aimed at risk groups, and consideration of mandatory immunization against Haemophilus influenzae b in children attending day care/nursery schools are needed.
