How do I use the VoICE tool?
The VoICE tool is a compendium of the many direct and downstream impacts of vaccine-preventable disease and immunization. The database contains summary explanations of the link between immunization and each impact, as well as sources of evidence for each link.
To use the VoICE tool, you can:
- Families, communities and individuals feel the effects of vaccine-preventable diseases and immunization in many different ways, including financially, physically and socially. To see how, navigate through the issues covered in the VoICE tool by choosing one of the 5 overarching vaccine-related topics, including: economics, education, equity, health, and health systems.
- First, choose a vaccine-related topic. The topics organize the impacts of vaccines and vaccine-preventable disease into broad categories. Hover over each topic icon to see how many ‘subtopics’, ‘key ideas’, and sources are available on that topic.
- ‘Subtopics’ are more specific areas related to the broader topic. For example, cost-effectiveness is a subtopic of economics. ‘Key ideas’ can be thought of as a description of the one specific link between immunization and the subtopic under which it falls.
- Click on a topic icon to expose the related subtopics. You can click on the topic icon itself to see a full list of results and sources, or
- Choose a subtopic to explore by clicking on the sub-topic.
- This page shows the key ideas related to the chosen subtopic. Other subtopics will remain on the left-hand side of the screen for easy navigation. Navigate to other subtopics at any time.‘Key results’ are summary statements of the applicable findings from supporting data sources. The source can be found under the key result, and can be expanded or hidden using the plus and minus sign.
- The blue tabs across the top allow users to manage ‘sources’. The number of related sources is always present in the upper right corner. Click on ‘export results’ the export results into an Excel file. Click ‘expand all’ to show all available sources or ‘collapse all’ to hide all available sources. All sources are hyperlinked. Click on the source link to view the source details, along with related information and similar sources.
Searching by keyword is useful when you are interested in a specific combination of factors such as a single vaccine in a specific world region. The option to search by keyword is always available by clicking on ‘search’ in the upper right corner of the page. This will query the entire VoICE database.
- Set up your search terms by selecting which topics, disease/vaccine, location, and year you are interested in. Select any factors in which you are interested by using the drop-down menus. If you don’t find what you were looking for, try different iterations of the keyword or try removing selections. For example, if you are interested in catastrophic health expenditures, try searching different terms such as poverty, non-discretionary expenditures, out of pocket expenses, etc.
- ‘Key results’ are the most important findings from relevant data sources. The source can be found under the key result and can be expanded or hidden using the plus and minus sign. An icon appears in the upper left corner of each key idea box. This icon indicates which broad topic area the information is related to – economics, education, equity, health, or health systems. The blue tabs across the top allow users to manage ‘sources’. The number of related sources is always present on the right side. Click on ‘export results’ the export results into an Excel file. Click ‘expand all’ to show all available sources or ‘collapse all’ to hide all available sources. All sources are hyperlinked. Click on the source link to view the source details, along with related sources. Clear all selections and start your search over by clicking on the ‘clear’ tab.
The content of the compendium is organized with increasing specificity as follows:
- Topic – overarching categories of vaccine and vaccine-preventable disease impacts. Each topic contains multiple subtopics.
- Subtopic – specific issues or categories of impact under one of the 5 topics. Each subtopic contains one or more Key Ideas
- Key idea – a statement illustrating one aspect of the relationship between vaccines/vaccine-preventable diseases and the subtopic under which the Key Idea falls.
- Key results – a summary of the specific conclusion or finding from a given source that supports the above Key Idea
- Source – the reference from which the corresponding Key results statement is taken
