1 | Formation of the Promoters of Optimal Routine Childhood Immunisation Coverage (PORCHIC) group: | By investigators: By PHC workers: By CORPs: |
| Primary members: Investigators, parents of newborn babies who were registered when their babies were aged 0–2 months, and primary healthcare (PHC) workers. Other members: Key community members (the cluster heads, community resource persons (CORPs), religious leaders and traditional birth attendants (TBAs) as locally relevant.
|
2 | Physical PORCHIC group discussion: | |
| Regarding non-receipt and untimely receipt of routine childhood vaccinations. To identify the determinants/proximal barriers and possible feasible solutions/strategies to addressing these barriers. To enlighten the PORCHIC group members and by extension other community members. To foster regular communications and working relationships between PORCHIC members.
| First PORCHIC discussion/meeting (first episode): Part 1 (Focus Group Discussion (FGD) on determinants):Discuss determinants of non-receipt and untimely receipt of routine childhood vaccinations, possible solutions and feasibility of executing these solutions during the study. Subdivide the FGD into two: Female PORCHIC FGD to consist of the investigators, female parents, PHC workers, CORPs, TBAs, etc as necessary. Male PORCHIC FGD to consist of the investigators, male parents, PHC workers CORPs, village heads, etc as necessary.
Part 2 (enlightenment group discussion):Introduce the research problem and purpose of the study. Let participants express their knowledge and perceptions regarding vaccines/vaccinations and routine childhood immunisation schedule. Explain key facts about vaccines/vaccinations, routine childhood immunisation schedule and optimal/timely receipt of vaccinations. Highlight key life-saving actions to practice and promote. Discuss comments, questions and answers.
|
| Second, third and fourth PORCHIC discussions or meetings:To get the views of the new PORCHIC members (registered after the previous discussion(s)) on the determinants of non-receipt and untimely receipt of routine childhood immunisations and possible solutions. To enlighten the new members and by extension other community members. To reinforce the knowledge and perceptions of the old PORCHIC members. To implement other solutions/strategies informed by the findings from the previous discussion(s) and engagements.
| Second to fourth PORCHIC discussions/meetings (second to fourth episodes): Part 1 (group discussion on determinants): Part 2 (enlightenment group discussion):Introduce the research problem and purpose of the study to the new participants. Let the old participants express their knowledge and perceptions regarding vaccines/vaccinations and routine childhood immunisation schedule. Let the new participants express their knowledge and perceptions regarding vaccines/vaccinations and routine childhood immunisation schedule. Explain key facts about vaccines/vaccinations, routine childhood immunisation schedule and optimal/timely receipt of vaccinations. Let the old participants highlight key life-saving actions to practice and promote. Highlight key life-saving actions to practice and promote. Discuss comments, questions and answers.

3 | Subsequent registration of parents of newborn babies as new members of the PORCHIC group: | By PHC workers:Continue to register parents of children aged 0–2 months as PORCHIC members. Briefly have enlightenment discussion with each mother or parent about optimal/timely receipt of routine childhood vaccinations.
