A recently released report of the Exploring Accreditation Project affirmatively answered the questions regarding the desirability and feasibility of establishing a national voluntary public health accreditation program. The report's recommendations were made after 10 months of inquiry from public health experts, elected officials, the general public health workforce, academicians, and other interested parties, more than 650 public health professionals in all. Recommendations regarding how such a program might be implemented insofar as its governance, principles for standards development, financing and incentives, and evaluation were included. The report provides a blueprint for establishing a national voluntary public health accreditation program. This article describes key aspects of the Steering Committee recommendations, with limited linkage to implementation strategies where relevant, in the four areas in which the project was designed. Details are provided in the final reports of the Steering Committee (www.exploringaccreditation.org) and in other articles in this issue.

Five years after primary infant immunization with trivalent oral poliovirus vaccine, employing either a three-dose primary series as recommended by the U.S. Public Health Service Advisory Committee on Immunization Practices (ACIP) or a four-dose series as recommended by the Committee on Infectious Diseases of the American Academy of Pediatrics, 115 children were serologically tested for persistence of neutralizing antibodies by the microneutralization test. Of the 57 individuals immunized according to the ACIP recommendation, antibody persistence was demonstrated in 92% for type 1 poliovirus, 98% for type 2, and 84% for type 3. Of those 58 individuals originally receiving a four-dose primary infant immunization series, the persistence of antibody was 98% to type 1, 98% to type 2, and 87% to type 3. Twenty-one of 24 negative sera showed neutralizing ability when tested by a more sensitive plaque reduction test. Thus, individuals completing either immunization schedule demonstrated satisfactory persistence of neutralizing antibody to all three poliovirus types over a five-year period.
