their vaccine needs. Nationally, discrepancies between estimated and actual vaccine requirements could amount to more than 1 million vaccine doses and tens of millions of dollars. In addition, CDC will give more attention to vaccine distribution and allocation to help ensure that states have equitable access to vaccines in short supply and that vaccines are targeted to recipients with the greatest need. Discussions with the states regarding a formula for allocation of Section 317 program funds are another component of CDC’s efforts to manage immunization resources effectively. CDC is also commissioning a new IOM study on financing vaccine purchase to develop long-term strategies for financing the costs of vaccine purchases.
