Vaccination saves more lives than any other health intervention.
But immunization can’t take place in a vacuum. By itself, it isn’t sufficient to transform the health of people in the poorest countries. A 2004 GAVI Alliance study found four principal barriers to increasing immunization coverage:
- Unpredictable funding in remote areas
- Lack of transportation
- A shortage of human resources
- A need for training and motivation.
To overcome these barriers, 49 of 72 GAVI-eligible countries have applied for funds to strengthen their health systems. Countries address a variety of bottlenecks with health systems strengthening funds.
