TY - JOUR AU - Binyaruka, Peter AU - Borghi, Josephine PY - 2018 DA - 2018/06/13 TI - Validity of parental recalls to estimate vaccination coverage: evidence from Tanzania JO - BMC Health Services Research SP - 440 VL - 18 IS - 1 AB - The estimates of vaccination coverage are measured from administrative data and from population based survey. While both card-based and recall data are collected through population survey, and the recall is when the card is missing, the preferred estimates remain of the card-based due to limited validity of parental recalls. As there is a concern of missing cards in poor settings, the evidence on validity of parental recalls is limited and varied across vaccine types, and therefore timely and needed. We validated the recalls against card-based data based on population survey in Tanzania.
