The VoICE tool is a compendium of the many direct and downstream impacts of vaccine-preventable disease and immunization. The database contains summary explanations of the link between immunization and each impact, as well as sources of evidence for each link. You can browse the VoICE tool by topic, or use the filters to find results based on topic, disease or vaccine, location and published year.

Key Evidence: The expertise and assets gained through efforts to eradicate polio at least partially explain the improvement between 2013 and 2015 in vaccination coverage of DPT3 in six out of ten “focus” countries of the Polio Eradication Endgame strategic plan. This includes substantial increases in vaccination rates in India, Nigeria, and Ethiopia, which, combined, reduced the number of children not fully vaccinated with DPT by 2 million in 2 years.

Key Evidence: Tens of millions of volunteers, social mobilizers, and health workers have participated in the Global Polio Eradication Initiative. The program contributes to efforts to deliver other health benefits, including health systems strengthening. Polio eradication legacy efforts include documenting and applying the lessons learned from polio eradication and transitioning the capacities, assets, and processes of polio to other key health priorities.

Key Evidence: Efforts to eliminate measles — which has been called a public health “canary in the coalmine” since it’s a sign of weak health systems — can also serve to strengthen immunization programs as well as the broader health systems. These efforts include improving infection prevention and control practices in health care facilities, disease surveillance and outbreak detection systems, and countries’ ability to prepare for and respond to infectious disease outbreaks.

Key Concept

Key Evidence: The detection of H1N1 influenza virus in Mexico in 2009, and subsequently throughout other countries in the Americas, benefited from the laboratory experience with measles and rubella in the region, leading to the rapid detection of and response to what eventually became a novel pandemic virus.

Key Evidence: Mothers infected with rubella virus during the first trimester of pregnancy can give birth to children with permanent disabilities such as intellectual impairment, autism, blindness, deafness, and cardiac defects. The infection is completely preventable if mothers are vaccinated before pregnancy.

Key Concept

Key Evidence: In the Americas, a platform built to secure polio eradication has been expanded to help track, control, prevent, and monitor immunization impact for measles and rubella. In India, highly trained polio health workers have become the basis for a trained workforce working towards the elimination of measles and rubella and helping ensure India’s certification by WHO for having eliminated maternal and neonatal tetanus.

Key Evidence: The Government of Nigeria used the Incident Management System (IMS) to establish a national Emergency Operations Center (EOC) as part of a new national emergency plan for the global polio eradication initiative. The use of IMS through the EOC changed the operational tempo, accountability measures, and programmatic success of the polio program. This existing infrastructure was in place and leveraged to contain the outbreak of Ebola.

Key Concept

Key Evidence: The American Academy of Pediatrics and the International Pediatric Association were included as partners in the measles and rubella elimination initiative, allowing for more direct collaboration around the interactions of primary health and immunization services and concerns.
