The Situation We Are Facing Is Not Necessarily The Situation We Planned For • Illness not as severe as 1918 scenario • Epidemiology of disease a bit different • Disease began in the North America • ? Larger amounts of vaccine available than in planning scenarios • ? Confluence of seasonal and pandemic vaccination in Fall 2009
H5N1 or “severe pandemic” Seasonal Influenza A 2009 H1N1 Vaccine Program Will Not Be The Same As A Program For…
Preparedness for 2009 H1N1 Vaccination Program • Implementation planning has started • Data to support future decisions • Southern Hemisphere epidemiologic and virologic data • Clinical trial results on immune responses and reactogenicity • Ongoing analyses of novel H1N1 epidemiology and virology in US
Planning Scenarios • Base Assumptions • Severity of illness remains the same • Risk groups remain the same • Unadjuvanted vaccine is immunogenic and safe • No major antigenic changes in novel H1N1
Planning Scenarios From Current Epidemiology and Base Assumptions • Children and staff in childcare centers and schools (K-12) • Pregnant women, young children, household contact of children <6 months of age • Persons with underlying medical conditions • Health care workers • When enough vaccine available: everyone
CDC H1N1 Vaccine Task Force • Implementation and Distribution • Uptake and Coverage • Safety Monitoring • Effectiveness • Communications
