摘要：

We studied coverage and timeliness of vaccination and risk factors for low and delayed vaccine uptake in children aged 2 years in rural Tanzania. We used data from a cluster survey conducted in 2004, which included 1403 children. Risk factors were analysed by log-binomial regression adjusted for the clustering. The analysis was restricted to BCG, first and third dose of DiphtheriaTetanusPertussis vaccines (DTP-1 and DTP-3) and first dose of measles-containing vaccine (MCV-1). Coverage for BCG, DTP-1, DTP-3 and MCV-1 was 94, 96, 90 and 86, respectively. Delayed vaccination (1 month after the recommended age) occurred in 398/1205 (33) children for BCG, 404/1189 (34) for DTP-1, 683/990 (69) for DTP-3 and 296/643 (46) for MCV-1. Coverage was lower for all vaccines except DTP-1 in children living 5km from a healthcare facility. Delayed uptake was associated with poverty. Low and delayed MCV-1 vaccination was associated with low maternal education. Delayed BCG vaccination was associated with ethnicity and rainy season. Despite reasonably high vaccination coverage, we observed substantial vaccination delays, particularly for DTP-3 and MCV-1. We found specific factors associated with low and/or delayed vaccine uptake. These findings can help to improve strategies to reach children who remain inadequately protected.
