Influence of Parental Knowledge and Opinions on 12-Month Diphtheria, Tetanus, and Pertussis Vaccination Rates

“…23-26 Studies using Social Cognition Models16 27-31 have provided useful insight, particularly the fear of vaccine harm as a barrier to immunisation. Yet the influence of variables incorporated in such models account for a relatively small proportion of the variance, when compared with simultaneously measured demographic variables 24…”

Immunization Status and Reasons for Immunization Delay Among Children Using Public Health Immunization Clinics

Causes Of Low Preschool Immunization Coverage In The United States

“…Despite potential methodological problems, studies have given consistent results. Most children begin the immunization series; coverage of first dose DTP was over 90% in many studies (9,16,29,39,44). The major problem is failure to complete the immunization schedule on time.…”

“…Record audits at emergency rooms (40), public clinics (24), and pediatric inpatient facilities (69) showed that up to 75.5% of children who attended did not receive all the vaccines for which they were eligible. A Utah study (39) indicated that illness of the child was a major reason for failure to immunize. In 1973, health department audits in Tennessee indicated that 10--24% of children had a missed immunization opportunity, most often because of delay Simplifying clinic procedures to reduce missed opportunities has dramati cally increased adult immunization rates.…”
