VoICE Immunization Evidence: Return on investment
The interruption of disease outbreaks through vaccination can yield a significant return on investment.
Key Evidence: Considering both the direct and indirect costs, researchers in the Netherlands estimated that the preventative immunization of Dutch healthcare workers (HCW) against pertussis (to reduce exposure and transmission contributing to outbreaks) results in a return on investment of 4 Euros to every 1 euro invested. This projection assumes an outbreak of pertussis once every 10 years.

Key Evidence: In a study of a 2003 outbreak of pertussis in the U.S., including 17 cases among healthcare workers, researchers estimated that vaccinating healthcare workers would result in a 2.4-fold return on investment for hospitals.
