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.

Adult Vaccines Policy Research

IVAC’s Adult Immunization project is designed to fill the need for a global platform that promotes awareness, facilitates technical consensus, provides leadership, and collaborates and coordinates with key stakeholders.

Baltimore City Partnership

Evaluation of Baltimore City Health Department Influenza Immunization Initiative Challenge There is concern about an increase in rates of both influenza and COVID-19 illnesses and deaths this coming 2020-2021 flu season and Baltimore City has committed to reaching the ambitious target of vaccinating at least 70% of its residents against influenza. Last season, although reporting […]

Pneumococcal Serotype Replacement and Distribution Estimation (PSERENADE) Project

Pneumococcal Serotype Replacement and Distribution Estimation (PSERENADE) Project The challenge Need better understanding of epidemiology, distribution & regional variability of serotypes causing invasive pneumococcal disease (IPD) Serotype replacement has been observed to vary by setting. Previous global serotype replacement analysis did not include LMICs and reflected PCV7 experience. Global analysis needed to inform development of […]

Social Media Research on Vaccine Hesitancy

Social Media Research on Vaccine Hesitancy Challenge Vaccine-preventable diseases are resurging as immunization coverage has decreased, driven by reductions in vaccine confidence and trust. Now a global phenomenon affecting low-, middle-, and high-income countries alike, the COVID-19 pandemic has further eroded trust in public health and catalyzed anti-vaccine sentiment. Its proliferation has been driven by […]

The International Council of Experts on Adult Vaccines (ICAI): advocating for global technical consensus and policy prioritization

The International Council on Adult Immunizations (ICAI): advocating for global technical consensus and policy prioritization CHALLENGE Older adult immunization has not been prioritized by global technical or policymakers, leading to its under-utilization. This era of COVID-19 only highlights the urgency for the global health community to act. With a small window of opportunity aligned with […]
