Validity of maternal recall for estimating childhood vaccination coverage - Evidence from Nigeria.

Background: Vaccination coverage surveys in low- and middle-income countries typically estimate vaccination coverage using data from vaccination cards, parental recall, or a combination of the two. However, these surveys are often complicated by the pervasive absence of vaccination cards, forcing researchers to rely on parental recall. We assessed the validity of mothers' recall against home-based vaccination cards using data from a community-based household survey in Nigeria.

Factors associated with incomplete immunisation in children aged 12-23 months at subnational level, Nigeria: a cross-sectional study.

Objectives: National immunisation coverage rate masks subnational immunisation coverage gaps at the state and local district levels. The objective of the current study was to determine the sociodemographic factors associated with incomplete immunisation in children at a sub-national level.

Design: Cross-sectional study using the WHO sampling method (2018 Reference Manual).

Perception and attitudinal factors contributing to periodic deworming of preschool children in an urban slum, Nigeria.

Background: Over 20 million preschool-age children (PSAC) in Nigeria require periodic chemotherapy (PC) for soil-transmitted helminth (STH) infections. Persistently low coverage for this age group threatens the World Health Organization (WHO) 2030 target for eliminating STH infections. Current strategies for targeting PSAC have been largely ineffective.
