Monitoring Anthrax Vaccine Adverse Events Defense Medical Surveillance System (DMSS) Michael McNeil, MD, MPH National Immunization Program NVAC, February 4th, 2004
Background • CDC was charged by Congress to undertake collaborative studies regarding the safety and efficacy of the anthrax vaccine adsorbed (AVA) • NIP is working collaboratively with the DoD and FDA to investigate potential adverse events associated with AVA using the DoD’s Defense Medical Surveillance System (DMSS)database
Purpose • To perform hypothesis testing and hypothesis generation with the DMSS • Examine the possibility that long term adverse effects are associated with AVA
Overview of the DMSS Project • How were the Topics Selected? • Potential Topics • Criteria for Prioritizing Topics • Suggested Priority Topics • Timeline • Next Steps
Sources for Topic Selection: • Institute of Medicine (IOM) • Anthrax Vaccine Expert Committee (AVEC) • Vaccine Adverse Event Reporting System (VAERS) • Medical and Public Health Literature • Vaccination Healthcare Center (VHC) • CDC, FDA, DoD • Public Opinion
Possible Topics for Investigation Endocrine SystemIntegument System Diabetes mellitus Rash with mucosal involvement Nervous SystemMusculoskeletal System Peripheral neuropathy Joint disorders Guillain-Barre Syndrome Myositis Demyelinating conditions
Possible Topics for Investigation Other Topics Syndromic illness Loss of duty Death Medical encounters Unintentional injury Cardiovascular System Atrial fibrillation Vasculitis Psychiatric Disorders Mood disorder
Criteria for Prioritizing Topics • Frequency of Occurrence • Feasibility • Severity of Effect • Likelihood of Association • Programmatic Interventions • Public Health Concern
Additional Considerations • Strengths and limitations of database • Effect of weighting (e.g., injuries) • Effect of deployment (e.g., atrial fibrillation) • Other topics (e.g., systemic lupus erythematosus, multiple immunizations)
Proposed High Ranking Topics for Full Protocols • Arthritis • Erythema multiforme • Optic neuritis • Systemic lupus erythematosus • Multiple immunizations
Timeline for the NVAC Vaccine Analytic Unit Workgroup • NVAC Meeting • Select members • Topic papers • Prioritize topics • Protocol Review (June 2004) June 2004 February 2004 June 2003 July 2003
Next Steps • Continue DMSS data validation • Award contract for chart abstraction • Draft full protocols for selected topics for IRB approval/clearance • Continue NVAC workgroup review
