About the Vaccine Resource Library

PATH’s Vaccine Resource Library (VRL) seeks to gather the world’s top immunization resources in a single portal. The VRL offers a wide variety of high-quality, scientifically accurate documents and links to resources on specific diseases and topics in immunization addressed by PATH’s work. It is geared toward health professionals in the developing and industrialized worlds, as well as journalists, policymakers, community leaders, parents, and anyone else interested in vaccine-related resources.


The resources found on the VRL are collected from a variety of sources, such as scientific journals, websites, news media, and public health
practitioners, as well as suggestions from VRL users. In addition to resources developed by PATH, the VRL contains materials published by international leaders in public health, including the US Centers for Disease Control and Prevention, the World Health Organization (WHO), Gavi, the Vaccine Alliance, and many others.

The VRL aims to provide useful information on numerous diseases, vaccines, and immunization topic areas. The VRL is not meant to be a comprehensive resource for information on all diseases, vaccines, and immunization topics; instead, it reflects those being addressed and advanced by PATH projects. There are many great general resources in the VRL that can provide you with guidance on subject areas that are not specifically covered. Please check back regularly as we continue to expand our resources to include additional diseases, vaccines, and immunization topics as PATH’s work evolves.

Maintenance and support

The VRL is maintained by a team of PATH staff members working on different vaccine- and immunization-related projects at PATH. Although PATH’s Center for Vaccine Innovation and Access leads the overall management of the VRL, it is truly a cross-programmatic effort, drawing input and assistance from across the organization.
PATH’s work on the VRL is indirectly supported by the vaccine- and immunization-related projects at PATH through the staff time spent making updates to the website. These projects receive funding from a variety of sources, including private foundations, governments, and individuals. The VRL does not receive direct financial support from the pharmaceutical industry, the US government, or any other funder. Learn more about PATH’s sources of funding.


The content of the VRL is reviewed regularly by PATH staff members working in the various areas represented within the site, including a formal annual review by relevant scientific and technical staff. As noted above, the VRL is a cross-programmatic effort at PATH, and we rely on the expertise of many colleagues across the organization to provide valuable input on new resources to add, updates to existing resources, outdated resources to remove, and changes to VRL web pages.

In addition, the VRL was assessed by the WHO and passed their "credibility and content good information practices criteria." It is included in the WHO’s list of vaccine safety websites.


Originally, the VRL served as the website for PATH’s Children’s Vaccine Program (CVP). Established in 1998, CVP worked to promote equal access to new and lifesaving vaccines worldwide. In partnership with the world’s leading immunization experts and national bodies, CVP aimed to repair crumbling immunization programs, build human and financial capacity within countries, and introduce new vaccines and immunization technologies. Although CVP is no longer active, the program’s groundbreaking work in vaccines and immunization continues in other programs at PATH. This report provides an overview of CVP achievements worldwide, with a special focus on China, India, and Indonesia.
