Assessment of the immunization status of practice children under five years of age.

Many professional groups are involved in immunization, and four different immunization records may be kept-the general practice record, the community child health record, the health visitor record and a record retained by the parent. The first three of these sources were examined for the immunization status of children under five years of age in a practice. The health visitor record was the most comprehensive. There was a remarkable improvement in pertussis vaccine acceptance over the four years reviewed but there were gaps in the uptake of measles vaccine.
