Summary

Child immunization is not a one-time behavior; rather, it is a repeated behavior within a specific timeframe. Not only the low immunization, but also the dropout of immunization and the delayed immunization from the recommended immunization schedule are prevalent and high in Africa. The most common reason for the incomplete vaccination is that caregivers thought the children had already been fully immunized (44.8%), according to Nigeria Multiple Indicator Cluster Survey (MICS) conducted in 2016/2017.

Caregivers' misconception of the complete immunization can be attributed to the complicated immunization schedule. In Nigeria, infants are supposed to receive 9 different types of vaccines at 5 different times within the first year since the births. To make things more complicated, the vaccine schedule changes over time; for example in Nigeria, the new vaccine, inactivated polio vaccine (IPV) was introduced in 2015 to be received at 14 weeks after births, and rotavirus vaccine and meningococcal A vaccine are scheduled for the introduction in 2019.

In this complicated and rapidly-changing environment regarding vaccination schedule, the goal of the study is to improve the understanding of vaccination completion and children's vaccination status among caregivers, which can then lead to the improved rate of full vaccination among children.

Objectives The main objectives of this study are to understand the impact of providing the general and tailored information on the vaccination schedule and vaccination status of women's children on the vaccine take-up. In this study, the investigators focus on women who has a child who is 12 months old or younger.

Hypothesis

The main hypothesis of this proposed study are as follows:

1. Information on vaccination among caregivers: the general and tailored information on vaccination schedule and child's vaccination status, improves the knowledge on benefit and understanding of vaccination completion, vaccination schedule and the vaccination status of the children among caregivers
2. Full immunization rate: through the improved knowledge level on the concept of vaccination completion and their children's vaccination status, the proposed study increases the full immunization rate among children
