1 VPD: Policy, Practice, Preparedness Conference An inside View of ACIP Vaccine Recommendations Larry K, Pickering, MD, FAAP, FIDSA July 23, 2012 National Center for Immunization & Respiratory Diseases Office of the Director FINANCIAL DISCLOSURE: Larry K. Pickering, M.D., F.A.A.P. In the past 12 months, I have not had a financial interest or other relationship with manufacturer(s) of product(s) or provider(s) of service(s) that will be discussed in this presentation. 2 Objectives To discuss responsibilities, structure, and function of the ACIP To review the process of immunization policy development in the U.S. To summarize interactions with professional organization and societies To highlight the GRADE process now used by ACIP To summarize key issues facing the ACIP 3 1

2 Diseases Prevented by Vaccination* 1986 (8) 2012 (17) Diphtheria Diphtheria Hepatitis A Tetanus Tetanus Hepatitis B Pertussis Pertussis Human papillomavirus Polio (OPV) Polio (IPV) Influenza Measles Measles Meningococcal disease Mumps Mumps Pneumococcal disease Rubella Rubella Rotavirus Hib disease Hib disease Varicella Zoster * Vaccines in routine immunization schedule in the U.S. 4 Advisory Committee on Immunization Practices Background - Origins and Role ACIP was established in 1964 by the Surgeon General of US Public Health Service ACIP designated by the FACA as a Federal Advisory Committee in 1972 Role: provide advice and guidance to the CDC Director, and the Secretary of HHS on most effective means to prevent vaccine-preventable diseases in the civilian population in the U.S. - Vaccines and related agents* - FDA-licensed vaccines (and unlicensed vaccines if warranted) * antisera, IG, antiviral agents 5 Advisory Committee on Immunization Practices VFC Program Vaccines for Children (VFC) Program established in August 1993, operational since October Unique statutory authority gives ACIP authority to determine vaccines provided in the VFC Program 6 2

5 CDC Approval Process Following an ACIP Vaccine Recommendation Brief Recommendation Full Recommendation ( ACIP Statement ) Published in MMWR Weekly as a Policy Note within 2 months of an ACIP vote Provisional recommendations are posted on ACIP website within 3 weeks of an ACIP vote *All ACIP recommendations are not final until approved by the CDC director and published in MMWR. Final recommendations are published in MMWR Recommendations & Reports within 6-8 months of an ACIP vote MMWR 2012: 61(25); Mmwr article 14 Expertise of ACIP Members Infectious diseases Immunology Virology and bacteriology Pediatrics including adolescent medicine Internal medicine Family medicine Nursing Public health, preventive medicine Vaccine research and policy Consumer concerns Economics, cost-effectiveness GRADE Process 15 5

6 Liaison Organizations* Members attend and participate in every ACIP meeting Members serve on ACIP work groups Five organizations assist with development and publication of immunization schedules All 30 liaison organizations support ACIP recommendations *non-voting 16 Immunization Policy Recommending Bodies Advisory Committee on Immunization Practices American Academy of Pediatrics Committee on Infectious Diseases American Academy of Family Physicians American College of Physicians American College of Obstetricians and Gynecologists 18 ACIP Work Groups Gather, analyze and prepare information for presentation to ACIP Develop draft policies/options for review/vote by full ACIP Work by teleconference throughout the year, and before/during ACIP meetings 19 6

7 ACIP Work Groups WG is chaired by an ACIP member and must include at least 1 other ACIP member Other members: lead CDC staff, other CDC staff including Immunization Safety Office, ex officio members, liaison representatives, invited consultants Task oriented WGs are disbanded when work complete; new WGs formed as required 20 ACIP Work Groups (WG) July 2012 PERMANENT WG TASK ORIENTED WG Adult Immunization General Recommendations Harmonized Schedule Influenza Hepatitis Vaccines Human Papillomavirus Vaccines Meningococcal Vaccines Pertussis-containing Vaccines Pneumococcal Vaccines Herpes Zoster (Shingles) Vaccine Japanese Encephalitis Vaccine MMR Vaccine

8 23 Advisory Committee on Immunization Practices Process 3 meetings annually February, June, and October. Each meeting is two days Agenda items - Topics solicited from ACIP members, liaisons, CDC staff and others using standard format - Finalized by ACIP Steering Committee Follow FACA* rules and procedures including meetings that are open to the public with time for public comment Meeting slides, live webcast archive, minutes posted on ACIP website Recommendations become final once approved by CDC Director and published in MMWR * Federal Advisory Committee 24 Act Standardization of ACIP Process Guidance for pregnant and breastfeeding women Economic analysis guidance - Vaccine acronyms and abbreviations Provisional recommendations Evidence based recommendations

9 Evidence Based Recommendations In October 2010 ACIP voted unanimously to adopt a methodology to assist in development of clear and uniform evidence assessment and reporting for future ACIP recommendations System used: Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework GRADE was implemented for new recommendations beginning in October HPV vaccine in males - Hepatitis B vaccine in people with diabetes mellitus 26 Institute of Medicine Eight standards for developing rigorous, trustworthy clinical practice guidelines Establishing transparency Management of conflict of interest Guideline development group composition Evidence based on systematic reviews Method for rating strength of recommendations Articulation of recommendations in a standardized form External review Updating Ref: IOM. Clinical Practice Guidelines We Can Trust. March 23, The ACIP Process: Evidence Considered in Immunization Policy Development FDA licensed indications and schedule Disease burden overall and in high risk groups Vaccine efficacy and effectiveness Data on safety in general and specific groups Feasibility in the context of existing recommendations Equity in access to vaccine and good use of public funds (cost effectiveness) Recommendations of other groups (AAP, AAFP, ACP, ACOG) 28 9

10 ACIP Recommendation Categories Category A recommendations are made for all persons in an age- or risk-factorbased group. Category B recommendations are made for individual clinical decision making. Evidence tables are used to summarize benefits and harms and strengths and limitations of the body of evidence. 29 Body of Evidence is Categorized into Four Types (1) Randomized controlled trials (RCTs), or overwhelming evidence from observational studies. (2) RCTs with important limitations, or exceptionally strong evidence from observational studies (OS). (3) RCTs with notable limitations or OS. (4) RCTs with several major limitations, OS with important limitations or clinical experience and observations.
