Charter
ACIP was established under section 222 of the Public Health Service Act (42 U.S.C. §2l7a) and is governed by its charter.
Policies and procedures
The ACIP policies and procedures document serves as a reference for ACIP members and interested members of the public about ACIP’s structure and functions.
The Advisory Committee on Immunization Practices (ACIP) is a federal advisory committee, composed of medical and public health experts, that provides advice and guidance to the Director of the Centers for Disease Control and Prevention (CDC) on the most effective means to prevent vaccine-preventable diseases in the United States.
ACIP’s guidance includes the use of vaccines, and may also include recommendations for administration of immune globulin preparations and/or antimicrobial therapy shown to be effective in controlling a disease for which a vaccine is available. In addition, ACIP has a statutory authority for the Vaccines for Children (VFC) program; ACIP has sole responsibility and authority to determine the vaccines, number of doses, schedule and contraindications for the VFC program. ACIP develops written recommendations—subject to the approval of the CDC Director—for the routine administration of vaccines to both pediatric and adult populations. To inform its advice to the CDC Director, ACIP considers disease epidemiology and burden of disease, vaccine efficacy and effectiveness, vaccine safety, the quality of evidence reviewed, economic analyses, and implementation issues. The overall goals of ACIP are to provide advice that will assist CDC and HHS in reducing the incidence of vaccine preventable diseases and to increase the safe usage of vaccines and related biological products, including active and passive immunoprophylaxis. The target populations for ACIP recommendations are public and private health care providers who administer vaccines, public and private officials who make vaccine policy, and the general public.
We will not cover these policies and procedures in any detail, but consult Reference 3 if you are interested.[3]

Authority
The ACIP was established under Section 222 of the Public Health Service Act (42 U.S.C. §2l7a), as amended. The Committee is governed by the provisions of the Federal Advisory Committee Act, Public Law 92-463 (5 U.S.C. § 1001 et seq.), as amended. The ACIP has been given statutory roles under subsections 1928(c)(2)(B)(i) and 1928(e) of the Social Security Act (42 U.S.C. § 1396s(c)(2)(B)(i) and 1396s(e)) and subsection 2713(a)(2) of the Public Health Service Act (42 U.S.C. § 300gg-13(a)(2)). Objective and Scope of Activities. The Secretary, Department of Health and Human Services (HHS), and by delegation the Director, Centers for Disease Control and Prevention (CDC), are authorized under Section 311 and Section 317 of the Public Health Service Act, [42 U.S.C. §243 and 42 U.S.C. §247b], as amended, to assist states and their political subdivisions in the prevention and control of communicable diseases; to advise the states on matters relating to the preservation and improvement of the public’s health; and to make grants to states and, in consultation with the state health authorities, to agencies and political subdivisions of states to assist in meeting the costs of communicable disease control programs.
The ACIP shall provide advice and guidance to the Director of the CDC regarding use of vaccines and related agents for effective control of vaccine-preventable diseases in the civilian population of the United States.
Recommendations made by the ACIP are reviewed by the CDC Director, and if adopted, are published as official CDC/HHS recommendations in the Morbidity and Mortality Weekly Report (MMWR).
The CDC Director informs the Secretary, HHS, and the Assistant Secretary for Health, of immunization recommendations. Upon the licensure of any vaccine or any new indication for a vaccine, the Committee shall, as appropriate, consider the use of the vaccine at its next regularly scheduled meeting. If the Committee does not make a recommendation at the Committee’s first regularly scheduled meeting, the Committee shall provide an update on the status of such for the Committee’s review.
Description of Duties
The Committee shall provide advice for the control of diseases for which a vaccine is licensed in the U.S. The guidance will address use of vaccines and may include recommendations for administration of immune globulin preparations and/or antimicrobial therapy shown to be effective in controlling a disease for which a vaccine is available.
Guidance for use of unlicensed vaccines may be developed if circumstances warrant.
For each vaccine, the Committee advises on population groups and/or circumstances in which a vaccine or related agent is recommended. The Committee also provides recommendations on contraindications and precautions for use of the vaccine and related agents and provides information on recognized adverse events. The Committee also may provide recommendations that address the general use of vaccines and immune globulin preparations as a class of biologic agents, use of specific antibody products for prevention of infectious diseases, and special situations or populations that may warrant modification of the routine recommendations.
Committee deliberations on use of vaccines to control disease in the U.S. shall include consideration of disease epidemiology and burden of disease, vaccine safety, vaccine efficacy and effectiveness, the quality of evidence reviewed, economic analyses, and implementation issues.
The Committee may revise or withdraw their recommendation(s) regarding a particular vaccine as new information on disease epidemiology, vaccine effectiveness or safety, economic considerations, or other data become available.
In accordance with Section 1928 of the Social Security Act, the ACIP also shall establish and periodically review and, as appropriate, revise the list of vaccines for administration to children and adolescents eligible to receive vaccines through the Vaccines for Children Program, along with schedules regarding the appropriate dose and dosing interval, and contraindications to administration of the pediatric vaccines.
The Secretary, and as delegated the CDC Director, shall use the list established by the ACIP for the purpose of the purchase, delivery, and administration of pediatric vaccines in the Vaccines for Children Program. Further, under provisions of the Affordable Care Act (Section 2713 of the Public Health Service Act, as amended), immunization recommendations of the Committee that have been adopted by the Director of the Centers for Disease Control and Prevention must be covered by applicable health plans.
