Notice F1: Implementation of the WHO digital documentation of COVID-19 certificates: vaccination status (DDCC:VS) technical specifications

Under Notice F1, Digital Square is accepting applications from existing digital health software tools (with a strong, but not exclusive, focus on point of care tools) that meet the definition of global goods and / or are existing approved Digital Square global goods to implement and align to the World Health Organization (WHO) published Digital documentation of COVID-19 certificates: vaccination status (DDCC:VS): technical specifications and implementation guidance. The key output is to showcase the tools as reference implementations of the technical guidance.

Applications are expected to align and strengthen the shelf-readiness aspects of the technologies and are encouraged to focus on strengthening capacities of new implementers/innovator groups in working and advancing global goods.

The guidance document is aimed to support and provide direction for countries and implementing partners on the technical requirements for developing digital information systems for issuing standards-based interoperable digital certificates for COVID-19 vaccination status, and considerations for implementation of such systems, for the purposes of continuity of care, and proof of vaccination.

The guidance document covers a range of topics and outlines scenarios such as "continuity of care" and "proof of vaccine", as well as frames the core data set and a national trust architecture for the DDCC:VS.

In addition to the published guideline, the WHO and community have created a HL7 FHIR implementation guide that is to be considered and adhered to in the application. More information can be found here:

Technologies and software being proposed in the applications must meet the following three minimum requirements to be seen as a global good.

  1. Be an existing software that has been deployed in three or more low-resource contexts.
  2. Be a global public good. Software tools will be considered a global public good if either:
    1. The source code is made available under an Open Source Initiative–approved software license; or
    2. The software is freely accessible and adheres to the Open Definition for access to data; or
    3. Software has been applied to a health domain to manage, analyze, or transmit health-related data.
  3. Content may be considered a global good if it is a resource, toolkit, or data standard that is available under an open license and that is used to improve or analyze health data management processes.

Applications must clearly identify how they plan to incorporate the guidance into their tool/solution as well have clearly outlined data exchange / interoperability solutions as well as metrics and means of testing these.

Applications must align to the principles of shelf-readiness and where appropriate ensure that the proposed technical development is aligned to the principles of shelf-readiness as a whole and with particular consideration to quality, documentation and installation

Applications must align their solutions to be part of the Instant OpenHIE project (as appropriate for deployment) and build into the testing approaches and infrastructure to ensure data exchange, the ability to showcase the exchange, and provide interoperability profiles required for the WHO DDCC:VS technical guidance.

Applicants are required to segment the applications into work packages. Work packages must be modelled  around core areas of the proposal and any aspects of shelf readiness that are being proposed. Care must be given to clearly indicate the gaps, activities and expected outputs/deliverables that the requested funding will go towards.

Applicants must ensure that the work packages are self-contained and not overly reliant on another. If there is a reliance this must be clearly called out and justified.

Examples of investments that will be made available through this call for applications include (but are not limited to):

  • Aligning a solution to incorporate key data standards and align to workflows.
  • Ensuring that applications can fulfill the data exchange needs of the WHO DDCC:VS technical guidance
  • Showcasing the technical guidance scenarios in their tool
  • Generating and or querying for data from trusted architecture
  • Aligning technologies to the DevOps guidelines and containerization deployment that is illustrated through use within the Instant OpenHIE project; and
  • Aligning of technologies to be better framed within the OpenHIE architecture and supporting the required workflows as per the OpenHIE architectural specification (as well as the associated test cases).

The following will be considered out-of-scope, and therefore make the concept note ineligible for funding:

  • Investments that are not applicable outside of a single health program area.
  • Investments in new functionality that are not justified in making the tool a shelf-ready solution.
  • Investments that are aimed to fund the implementation of the solution within a project (i.e. the funding is intended for technical development and not implementation work / activities).

Applications must include a motivation as to the focus of the selected technology and why the inclusion of WHO DDCC:VS technical guidance within is the tool to a valued/important investment tied to health outcomes and opportunities. Connecting the motivation to existing field implementations requests and potential use is encouraged.

Local capacity development

Digital Square is committed to enhancing and expanding the capacities of local enterprises and new team to support the development, enhancement and deployment of global goods. As such applications are encouraged to seek out opportunities to build local capacity in local teams and new innovators and expand the global good communities through this opportunity. 

Open source and global Access

Work proposed in the applications must align to global access principles and be made available under an appropriate open-source license. Applications must clearly outline the licensing of proposed work items in the application.
