| 1. | The intention to receive COVID-19 vaccination | The proportion of community members aged 15 years and above, who have not received COVID-19 vaccination, who intend (or plan) to receive COVID-19 vaccination that is available for them to receive. The component outcomes are those who will surely go and receive and those who think they will go and receive the vaccination. This outcome is in contrast to those who do not intend (or plan) to receive COVID-19 vaccination that is available for them to receive—consisting of those who are not sure, those who think they will not go and receive, and those who will surely not go and receive the vaccination. |
| 2. | Timeliness of the intention to receive COVID-19 vaccination | The time (in days) that community members aged 15 years and above, who intend (or plan) to receive COVID-19 vaccination, intend (or plan) to take before they go and receive the vaccination. The component outcomes are the intended time to vaccination among those who will surely go and receive and those who think they will go and receive the vaccination. |
| 3. | The uptake of COVID-19 vaccination | The proportion of community members aged 18 years and above who have received COVID-19 vaccination |
| 4. | The hesitancy to COVID-19 vaccination (delay or refusal to receive) | The proportion of community members aged 18 years and above who have not received COVID-19 vaccination due to reasons that include only non-acceptance factor rather than only real/perceived non-availability/non-access factor or both non-acceptance and real/perceived non-availability/non-access factors. Non-acceptance factor is defined as consisting of one or more of: perceptions that the vaccination is not important, vaccine is not safe, vaccine is not effective, vaccine is new and/or waiting for others to take it first, and hearing of many bad stories about the vaccine. Real/perceived non-availability/non-access factor is defined as consisting of one or more of: ignorance of vaccination availability, ignorance of place and/or time of vaccination, long distance to vaccination site, being too busy, being ill and did not go for vaccination, being ill and went for vaccination but was not given, long waiting time, vaccine stock-out, absence of vaccinator, closure of health facility. The non-acceptance and real/perceived non-availability/non-access factors will be measured as the reasons given by respondents regarding why they have not received COVID-19 vaccination. Delay in receiving COVID-19 vaccination is the intention to receive the vaccination among those that are hesitant. Refusal to receive COVID-19 vaccination is the intention not to receive the vaccination among those that are hesitant. |
| 5. | The intention for the children to receive COVID-19 vaccination | The proportion of community members aged 15 years and above who intend (or plan) for their children to receive COVID-19 vaccination if it is available for them to receive.
