Vaccination is among the most cost-effective health interventions and has attracted ever greater levels of investment from public and private funders. However, some countries, mainly populous lower-middle-income countries, are lagging behind in vaccination financing and performance.
In this paper, Amanda Glassman, Juan Ignacio Zoloa, and Denizhan Duran discuss the rationale for investing in vaccination and construct a metric to measure countries’ commitment to vaccination that would promote accountability and better tracking of performance.
