Estimates of immunization coverage in developing countries are typically made on a heard plus history basis. combining information obtained from vaccination cards with information from mothers'reports, for children for whom such cards are not available.
A recent survey in rural lower Egypt was able to test the accuracy of mothers'reports for a subset of children whose cards were not seen at round 1 of the survey but were seen a year later at round 3. Comparisons of the unsubstantiated reports at round I with information recorded from cards seen at round 3 indicate that mothers'reports are of very high quality ; mothers'reports at round 1 were confirmed by card data at round 3 for between 83 and 93%, depending on vaccine. of children aged 12-23 months. and for 88 to 98% of children aged 24-35 months.
Mothers of children who had not been vaccinated were more likely to give consistent responses than were mothers of vaccinated children.
Thus, these « card plus history »estimates slightly understate true coverage levels.
Most of the inconsistencies between round 1 and round 1 data apparently arose from interviewer or data processing error rather than from misreporting by mothers.
