VIEW-hub – Vaccine Information and Epidemiology Window

IVAC serves as a home to VIEW-hub, a new online, interactive vaccine information tool. VIEW-hub is a publicly accessible, interactive platform that enables users to visualize real-time information on vaccine use, product type, coverage levels, and impact assessments.

Through VIEW-hub, users can instantly visualize data about vaccine introductions, product usage, dosing schedules, access, coverage, and more for a number of vaccines. Custom queries and maps, exportable data and graphics, and a map gallery are just some of the interactive features users can access. VIEW-hub extends the functionality and content of the former Vaccine Information Management System (VIMS), allowing users to track progress and strategize ways to accelerate and optimize vaccine implementation.

About VIEW-hub

What does VIEW-hub do?

  • Monitor vaccine implementation and impact evaluation, both globally and at the country level
  • Monitor where impact studies have been conducted and what they are assessing
  • Enable assessments that identify gaps in vaccine use and evaluation

How does VIEW-hub do this?

VIEW-hub compiles data from a variety of official and unofficial vetted partner sources in a central platform where data visualization and summaries can be easily generated and customized. Data are gathered systematically across official sources as needed to ensure validity.

Vaccine introduction data are updated in real-time where possible. Other data, such as vaccine coverage, are updated annually. PCV impact study data are updated systematically, on a weekly or quarterly basis.

What is the scope of VIEW-hub?

VIEW-hub includes the following vaccines:

  • Haemophilus influenzae type b (Hib) vaccine
  • Pneumococcal conjugate vaccine (PCV)
  • Rotavirus vaccine
  • Inactivated polio vaccine (IPV)

VIEW-hub provides information on theses data topics:

  • Vaccine introductions and use
    • Program type
    • Product
    • Dosing schedule
  • Vaccine impact assessments (PCV and rotavirus vaccine)
    • Location
    • Outcomes evaluated*
    • Study population*
    • Availability of results and links to publications*
  • Vaccine coverage
  • Vaccine-preventable disease burden
  • Immunization equity*

*Coming soon

What sources does VIEW-hub use?

Vaccine introduction and use information is sourced from the Immunization Data Repository and other official WHO sources, UNICEF, Gavi, government ministry of health websites, and vetted media sources. PCV impact study information is sourced from Gavi, the Bill & Melinda Gates Foundation, CDC, recurring literature searches, and communication with partners.

VIMS Report on Global Vaccine Introduction (2012-2015)

VIMS (Vaccine Information Management System) was a web-based tool launched in 2007 to provide the international community with data on the state of vaccine access in 194 countries. VIMS has transitioned to VIEW-hub, a new data visualization platform focused on vaccine introduction and impact. Previous VIMS reports for 2012-2015 are available here.
