IVAC Projects

IVAC has five teams that work together to support our mission: Epidemiology, Economics & Finance, Policy, Advocacy & Communications, Operations Research, and Operations.



Epidemiology

Baseline Assessment for Streptococcus Pneumoniae of India Serotypes (BASIS)

The objective of the BASIS project is to establish a surveillance platform to characterize the serotype distribution of Streptococcus pneumoniae causing invasive disease among children younger than five years of age in India. Funded by the Bill & Melinda Gates Foundation, the BASIS project builds on the recently completed ASIP study to continue surveillance for invasive pneumococcal disease to provide the evidence-base in India for selection of an appropriate pneumococcal conjugate vaccine and baseline information to evaluate the impact of vaccine introduction on serotype distribution.

Pneumonia Etiology Research for Child Health (PERCH)

Pneumonia Etiology Research for Child Health

Existing knowledge on the etiologies of childhood pneumonia is largely based on studies from the 1980s and 1990s. With expanded use of pneumococcal conjugate vaccine and Hib vaccine and changes in host and environmental factors, a new evidence base that harnesses novel technologies for diagnosis is needed. The Pneumonia Etiology Research for Child Health (PERCH) study, funded by the Bill and Melinda Gates Foundation, is a case-control study to determine the etiology of and risk factors for severe and very severe pneumonia in children aged 1-59 months.  PERCH has enrolled approximately 4,000 hospitalized cases and 5,000 community controls from 7 African and Asian countries selected to be representative of areas where most of the severe pneumonia cases in children are expected to occur in 2015.

Economics & Finance

The Decade of Vaccine Economics (DOVE), Phase IV

The DOVE project estimates the global economic benefits, costs, financing, funding gap, and return on investment in national immunization programs. We have developed a suite of updatable models that look across 94 low- and middle-income countries and 10-18 antigens, during Decade of Vaccines (2011-2020). Funded by the Bill and Melinda Gates Foundation (BMGF), the models enable funding partners and international bodies such as BMGF, Gavi Secretariat, UNICEF, and the World Health Organization to make informed decisions on global vaccine investments and strategies. Phase IV of the DOVE project will involve assessing the economic impact of vaccination by gathering primary data on the averted cost of illness due to vaccine preventable diseases in select countries, as well as updating and extending existing DOVE vaccine economic models.

Partners include:

  • Bill & Melinda Gates Foundation
  • Gavi Alliance
  • UNICEF
  • World Health Organization
  • Rutgers University
  • University of Pittsburgh School of Engineering
  • Carnegie Mellon University

Dengue Vaccine Initiative (DVI)

Dengue Vaccine InitiativeThe DVI is a collaboration between the International Vaccine Institute, the Sabin Vaccine Institute, the World Health Organization, and IVAC that aims to support the effective and prompt introduction of dengue vaccines in dengue-endemic countries by conducting evidence-based research to inform policy. Current work is focused on quantifying the regional and country-level demand for dengue vaccines in dengue-endemic, engaging with GAVI and contributing to preparation of investment cases. Our work also involves developing innovative financing alternatives for dengue vaccines and helping countries with budget impact analyses and other types of impact studies.

Partners:

  • International Vaccine Institute (IVI)
  • The Sabin Vaccine Institute
  • World Health Organization

Policy, Advocacy & Communications

Building an Enabling Environment for Vaccines in India - Phase II (EEVI2)

Funded by the Bill and Melinda Gates Foundation, IVAC provides ongoing technical support and expertise to inform decision making and encourage advocacy for Hib, pneumococcal conjugate and rotavirus vaccines  at a center, state, and local level. The project aims to create an environment that enables timely, evidence-based policies and decisions for nationwide introduction and delivery of pentavalent, rotavirus, and pneumococcal vaccines into India’s Universal Immunization Programme, while simultaneously raising the volume of political and public discussion around the value of vaccines and a high quality routine immunization system as a necessary part of cost-effective, integrated public health. With partners, the project engages local stakeholders (government, experts, civil society, financial stakeholders, parliamentarians, state and local leaders and others) to not only understand and use the data, but to take ownership and drive the process based on their vision for their own country that recognizes the broad value of vaccines. EEVI works closely with government, partners and civil society to help justify  increased investments in new vaccines and the system to support improved coverage and equity in the context of a comprehensive approach to disease prevention.

Rotavirus Organization of Technical Allies (ROTA) Council

IVAC chairs the ROTA Council, comprising 19 international expert members and three core partners, and its support team in the Council’s mission to provide the scientific and technical evidence policy makers and other key stakeholders need to accelerate the introduction of rotavirus vaccine in high-burden countries. The Council provides a credible source of information and guidance for decision-makers by building scientific and technical consensus around rotavirus vaccines and works to identify key strategies to resolve potential barriers to vaccine introduction in countries. The Council continues to provide critical scientific and technical evidence, strengthen partnerships across the diarrheal disease community, and engage with in-country champions to raise awareness about rotavirus disease burden and the potential impact of vaccines in order to build support for introduction decisions.

Operations Research

HERMES-logoHighly Extensible Resource for Modeling Event-Driven Supply Chains (HERMES)

The Highly Extensible Resource for Modeling Event-Driven Supply Chains (HERMES) Logistics Modeling Team focuses on developing computational models and tools to improve the delivery of healthcare goods, such as vaccines, throughout the world and consists of professionals from IVAC at the Johns Hopkins Bloomberg School of Public Health, the University of Pittsburgh Department of Industrial Engineering, and the Pittsburgh Supercomputing Center (PSC).  An example of a tool that the team developed is HERMES, a computational tool for designing, planning, and improving healthcare supply chains. Distributing vaccines (and other healthcare products) can be a complex process, integrating many steps, locations, personnel, and equipment. HERMES will be a free and accessible supply chain modeling tool that’s designed to help various stakeholders make informed decisions about health policy, particularly vaccine introductions and modifications. Countries where HERMES has been applied to support decision making regarding vaccine use and delivery systems are Niger, Senegal, Benin, Vietnam, Thailand, Kenya, Chad, Mozambique, and India. The project is supported by the Bill & Melinda Gates Foundation and UNICEF.

Other IVAC Projects

The IVAC team is also involved in a range of other, smaller projects aimed at improving vaccine access including studies of the vaccine decision-making process in Peru; the use of oral fluid assays to monitor vaccine coverage in Bangladesh; exploring the relationship between distance from a health center or hospital, vaccination coverage, and overall mortality; how to leverage the experience and skills of consumer goods companies to improve delivery of vaccines in remote areas; and policy and ethical issues related to the introduction of new vaccines in middle-income countries.
