Childhood immunization in the State of Qatar: Implications for improving coverage

In Qatar, there is evidence of underuse of the immunization services despite easy access to health care. We therefore undertook a prospective study to determine the vaccination status and, more importantly, the reasons for inadequate immunization of a group of 255 preschool children attending the outpatient care facilities in Doha. A questionnaire was used to obtain relevant information, including parent's educational background. Sixty-six percent of the children were fully immunized for their age group, 12% were partially immunized, and 12% were not immunized. Eighty-eight percent had received their first dose of DPT/OPV, but only 57% had received their first booster by 18 months of age; 76% had received three doses of DPT/OPV. The main reasons for nonimmunized status were misinformation and lack of awareness in parents about vaccination. Parental oversight, misinformation, and medical deferral were the main reasons for partial immunization. Parents of unimmunized children were often illiterate. In Qatar, establishment of an aggressive ongoing public education campaign, as well as strict implementation of the World Health Organization's Expanded Programme on Immunization's policy of screenign all children at every health care contact for the need for vaccination, should substantially increase immunization coverage. Implementation of a recall system for defaulters should also lead to improved immunization rates.
