What We Do

The International Vaccine Access Center accelerates equitable and sustainable access to vaccines in low- and middle-income countries by generating, synthesizing, and using evidence to inform decision making and action.

Our Approach Blends
  • Rigorous science
  • Productive partnership
  • Clear communication
  • Capacity building and training

Our Practice Areas

Country Support

Based on demand from country leaders and health agencies around the world, we provide independent policy advice, support country vaccine decision-making and governance, and connect partners to accelerate progress toward health and development goals.

Coverage & Equity

To improve equitable immunization within and between countries, we help countries better measure vaccine coverage, interpret results for action, and boost demand for vaccination using novel strategies.

Major studies evaluate the feasibility of using blood samples to identify gaps in immunity and implement mobile-based reminder systems, two approaches that could be adopted by governments to strengthen vaccination programs and protect all children.

Disease Epidemiology

To inform and improve prevention and control strategies, we manage large clinical studies and surveillance networks. We also quantify the amount of disease in countries and globally via mathematical models constructed with an understanding of population-level epidemiology, health system, and policy contexts.

Economics & Finance

To support investment and funding decisions, we quantify the cost of illness from diseases and determine the economic return on investment of vaccine use. We also help countries identify and address financing and affordability challenges.

Impact Evaluation

To inform policy & investments, we evaluate how vaccines reduce the spread of disease and create other value post introduction and over time.

Operations Research

To support the introduction of new vaccines and improvements in coverage, we analyze the programmatic and logistical implications of policy choices, such as variations in shipping, packaging, and other operational decisions that affect cost and health impact. Digital tools aid countries in designing, planning, and improving supply chains.

Policy Engagement

As a leading contributor to global immunization policy, we synthesize & present evidence to build consensus, inform strategy and support policy development. Members of IVAC’s leadership serve on the WHO Strategic Advisory Group of Experts (SAGE) and on several WHO working groups.

Technical Advocacy

To advance evidence-based policy, we support technically driven efforts, led by global and in-country partners, to understand the value of vaccines. We develop compendiums of published evidence, formulate messaging, and develop advocacy materials. We also build and manage coalitions and networks of scientists and other health advocates.

Pneumonia Research and Vaccine Impact League (PREVAIL)

This study will establish and maintain a surveillance network to measure the impact of routine infant vaccination with PCV on serotypes causing invasive pneumococcal disease among young children under 5 years of age in India.

Strengthening Immunization Systems through Serosurveillance (SISS)

Strengthening Immunization Systems through Serosurveillance (SISS) The challenge Achieving global and regional goals on vaccination and disease elimination requires identifying and vaccinating unvaccinated and unimmunized children and adults. Serological surveillance for vaccine preventable diseases (VPDs) provides an opportunity to directly monitor population immunity and identify immunity gaps that cannot be sufficiently characterized using conventional vaccination […]

Vaccine Information and Epidemiology Window (VIEW-hub)

VIEW-hub is IVAC’s publicly accessible interactive platform to visualize real-time information on vaccine use, product type, coverage levels, impact assessments, and disease burden estimates. It can be utilized to track progress and strategize ways to accelerate and optimize vaccine implementation.
