Meet the team

PVA is an alliance powered by its members. With a membership of over 100 organisations and hundreds of influential individuals, our work is driven by the collaboration, dedication and time given to the project by alliance members’ staff. In addition to these members and the alliance’s co-chairs, we also have a team who are employed to work directly for the alliance. You can learn more about them and their work below, and contact us on [email protected] where we can help direct your request.

You can also skip to learn more about: PVA’s structure, PVA’s administrative team, and the donors who make our work possible.

Chalita Auesiritrakul

Regional Campaign Coordinator for Asia

Chalita updates the steering committee about social media engagements and broadens PVA’s voice through online platforms. She leads on online presence, enhancing the organization’s visibility and outreach on various social media channels. She also develops organizational materials and tools for events.

As part of the alliance’s commitment to tackling the Northern bias that exists in global health, upon receipt of its grants to fund work from 2021-2023, the People’s Vaccine Alliance Steering Committee agreed to allocate funding and staff with a direct focus on Global South regions that have traditionally been underfunded and underrepresented. The Regional Leads and their teams particularly focus on setting strategic direction for, and supporting, collaborating with and providing funds for their region. Each of the regions have their own network of organisations (some also part of the global network) and work independently driven by their own regional agendas rooted in the PVA global manifesto. You can follow them on Twitter at @PVA_Asia, @Vacunas_LAC and @PVA_Africa.

Fiscal Management and Legal Administration

The People’s Vaccine Alliance is additionally supported by Global Justice Now, the alliance member that currently serves as the fiscal and legal host for the alliance. The PVA would like to acknowledge and thank Global Justice Now’s support.

Structure of the alliance

The People’s Vaccine Alliance is led by a Steering Committee which is made up of the Alliance Co-chairs Winnie and Max, the Regional Leads and the Co-Chairs of the Alliance’s working groups. The Committee is responsible for approving the Alliance’s priorities, memberships and sign off structures among other responsibilities.

The working groups are a set of groups open to all alliance members. These cover key areas of the alliance such as Policy and Advocacy, and Campaigns and Media. The groups meet regularly, and are where the majority of the ongoing work and collaborations of the alliance takes place. Groups are led by two Co-chairs, one from the Global North and one from the Global South. There is also a fortnightly all-alliance call, open to all members, to collaborate and update across the whole alliance.

The groups sometimes form smaller sub-groups which focus on a particular area. These are narrower in focus, usually do not require a chair, and are often time bound, and disband after achieving their goal.

Funding for the alliance

The People’s Vaccine Alliance is grateful for the members that generously provided staff time and secured funding during its first year and to donors who make its growth and work still possible. The Alliance has received $3.7M from the following donors: Ford Foundation, Rockefeller Brothers Fund, Archewell Foundation, Open Society Foundations and Wellspring Philanthropic Fund.

A portion of these funds enable the work of the global alliance, another portion is managed directly by the regional teams and a further portion is dedicated to the PVA’s Agility Fund.

The Agility Fund is designed to provide rapid, small-to-medium sized grants of up to $15,000 to support work that helps to ensure equitable access to Covid-19 vaccines, tests and treatments. You can learn more about the Agility Fund here. To date, the PVA has run two rounds of the Agility Fund, in May 2022 and September 2022. It has successfully awarded over 30 grants to local organisations, enabling these to advocate and campaign for vaccine equity on local and national levels.
