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

Primary | Number of participants who have the accurate knowledge level of vaccination, as assessed by survey questionnaire | The investigators will collect the information on respondents' knowledge on vaccination through surveys. The knowledge level is calculated from 5 questions: 1) the number of type of vaccines a child needs to receive before 12 months old, 2) the number of times a child needs to receive Pentavalent vaccine, 3) the last month when a child needs to receive Pentavalent vaccine, 4) the timing when a child needs to receive BCG vaccine, and 5) the number of clinic visits (at minimum) a child needs to make for complete vaccination. For each question, the score is 0 if wrong, or 1 if correct. The knowledge level scale ranges from 0 to 5, which is the total number of correct answers. |
