A bill to amend the Public Health Service Act to ensure an adequate supply of vaccines.

Amends the Public Health Service Act to require the Secretary of Health and Human Services, acting through the Director of the Centers for Disease Control and Prevention, to develop a plan for the purchase, storage, and rotation of vaccines and submit it to Congress. Declares that the supply of vaccines should be sufficient to provide for adults and children, for a six-month period, all vaccinations routinely recommended by the Advisory Committee on Immunization Practices. Directs the Secretary to require a manufacturer of a vaccine included in such supply to provide a one-year notice to the Secretary of a discontinuance of the manufacture of the vaccine or of other factors that may impede the supply of the vaccine. Permits a reduction of the period of notice for good cause. Authorizes appropriations through FY 2009.
