Challenges to building capacity for evidence-based new vaccine policy in developing countries.

There are many challenges to ensuring that people in developing countries have equitable access to new vaccines. Two of the most important are having the capacity to make evidence-based new vaccine policy decisions in developing countries, and then when appropriate actually distributing those new vaccines to those who will most benefit from them. Based on our review of the Pan American Health Organization's ProVac Initiative in the Americas, we found that when national governments in developing countries develop the expertise to make the best technical decisions about immunization programs; take responsibility for helping to pay for and distribute vaccines; and are supported by strong partnerships with international organizations, they succeed in saving more lives more quickly.
