This report of the Austin workshop summarizes the findings of the previous IOM report and reviews continuing challenges in immunization finance for the nation and for individual states, with a particular focus on Texas. The report also highlights strategies proposed by individual workshop participants that can be used to address those challenges. Several presenters and discussants emphasized that adequate funding is necessary for immunization programs but that financial resources alone are not sufficient to guarantee success. Similarly, they indicated that no single agency or group in the public or the private sector should expect, or should be expected, to solve immunization problems. Speakers from both public and private health agencies observed that collaboration, consultation, and partnership efforts across levels of government and between the public and private sectors are essential.
