18 Slide 18 of 25 Vaccine Effectiveness AFHSC – Retrospective analysis, case/control (1:4) of seasonal influenza vaccine against clinically apparent, laboratory-confirmed 2009 A/H1N1 associated illness Modest VE (22%): Many active duty with multiple prior vaccinations and unique experience with respiratory pathogen exposure Naval Health Research Center (NHRC) – Population-based, flu-confirmed, febrile-respiratory illness surveillance of recruits at 8 training centers (since 2003)**( Russell 2004; Strickler 2007) 03/04--94%; 04/05--86%; 05/06--92%; 06/07--87%; 07/08--81%; 08/09--79%; 09/10--insufficient cases after vaccination instituted USAF School of Aerospace Medicine (USAFSAM) – Population-based of observed as compared to expected influenza cases as determined by vaccination coverage**( Orenstein 1985; Farrington 1993) Estimate of vaccine effectiveness (not clinical VE) No VE demonstrated

19 Slide 19 of 25 Vaccine Effectiveness Unfortunately Unable to examine pandemic 2009 H1N1 vaccine effectiveness due to high seasonal vaccination coverage (~92%) and small case count occurring after pandemic vaccination

20 Slide 20 of 25 H1N1 Vaccine Safety Collaboration between MILVAX and AFHSC, in conjunction with the FDA's CBER and the CDC's Immunization Safety Office AFHSC’s DMSS searched weekly to identify all H1N1 vaccinations Outcomes – Anaphylaxis – Bell’s palsy – Idiopathic thrombocytopenia – Acute disseminated encephalomyelitis – Guillain-Barré Syndrome – Acute transverse myelitis – Optic neuritis Rapid cycle statistical analysis of aggregated data – Comparison to past 3 seasonal influenza vaccine campaigns – Identify in near real-time increased occurrences of outcomes

21 Slide 21 of 25 H1N1 Vaccine Safety Potential cases verified by FDA and DoD neurologists and immunologists Safety surveillance conducted on over 1 Million Service members receiving the Novel A(H1N1) vaccine There continues to be no increase in safety concerns compared to previous seasonal influenza vaccine campaigns

22 Slide 22 of 25 Susceptibility Studies Utilize DoD serum repository Determine existing rates of seroconversion – True incidence of 2009 H1N1 – HAI and Microneutralization – From 01 May—Feb 2010 Associate with – Known 2009 H1N1 infection – Medical care – Complications – Co-morbidities – Prior vaccinations

23 Slide 23 of 25 Summary The DoD maintains a global laboratory-based influenza surveillance program – military and civilian populations – underserved regions of the world Molecular analysis of 2009 A/H1N1 specimens indicate an overall protein identity of 97.9 – 99.4% compared to the vaccine strain Molecular analysis of A/H3 specimens supports a change of vaccine composition for the next season from A/Brisbane to A/Perth like strain We were unable to perform 2009 H1N1 vaccine VE determinations – Seasonal vaccination studies suggest at most mild protection toward 2009 H1N1 No increase in vaccine safety concerns
