Director, BARDA

Deputy Assistant Secretary, ASPR

November 14, 2012


U s pandemic influenza plans laid the pathway for pandemic vaccines

U.S. Pandemic Influenza Plans Laid the Pathway for Pandemic Vaccines


Vaccine strategic goals were specific on expectations

Vaccine Strategic Goals Were Specific on Expectations

  • Goal #1: Establish & maintain dynamic pre-pandemic influenza vaccine stockpiles available for 20 M persons (2 doses/person): H5N1 stockpiles

  • Goal #2: Provide pandemic vaccine to all U.S. citizens within 6 months of a pandemic declaration: pandemic vaccine (600 M doses)

    National Strategy for Pandemic Influenza (Nov 2005) and HHS Pandemic Influenza Plan (Nov 2005)

Vaccine Development, Planning, & Infrastructure Must Address Both

Seasonal and Pandemic Influenza

Preparedness

for other

hazards

Pandemic Influenza

Preparedness

Seasonal Influenza

Preparedness

Unifying Principle


Pandemic influenza vaccine implementation goals

Pandemic Influenza Vaccine Implementation Goals

Fortify existing influenza vaccine capabilities

Support development of better influenza vaccines that afford greater surge manufacturing capacity

Cell-based Vaccines

Recombinant and Molecular Vaccines

Adjuvants for Dose- and Antigen-sparing

Universal Influenza Vaccines

Establish pre-pandemic influenza vaccine stockpile

Expand domestic manufacturing capacity

Retrofit existing facilities

Establish new facilities


National pandemic influenza vaccine development strategy is multi step integrated approach

National Pandemic Influenza Vaccine Development Strategy Is Multi-Step & Integrated Approach

Universal Vaccines

Antigen-Sparing Vaccine Technology

Recombinant-based Vaccines

Cell-based Vaccines

Egg-based Vaccines

“More and better vaccines sooner”

Hhs has supported development of multiple antigen sparing flu vaccine adjuvant technologies

HHS Has Supported Development of Multiple Antigen-sparing Flu Vaccine Adjuvant Technologies

Supported multiple projects in 2007-09 (H5N1) & in 2009 (H1N1) for advanced development of pandemic influenza vaccines with adjuvants towards US-licensure

Vaccine candidates are at various stages of development with Q-Pan representing one mature vaccine candidate

Multiple study results (academia, USG, & vax mfg.) have shown that different oil-in-water emulsion adjuvants confer additional properties onto flu vaccines

antigen- & dose-sparing effects

cross-strain protection

prolonged prime-boost immunity

Mix-N-Match studies showed that H1 and H5 vaccine antigens from one manufacturer combined with adjuvants from other manufacturers are immunogenic


Hhs has established h5n1 vaccine stockpile available for deployment

HHS Has Established H5N1 Vaccine Stockpile Available for Deployment

HHS/BARDA established & manages H5N1 vaccine antigen (4 strains) and adjuvant (2) stockpiles stored and routinely tested at domestic vaccine manufacturing sites

U.S. pan flu preparedness stockpiling goal met in 2008

Stockpile needs evaluated annually using CDC’S Influenza Risk Assessment Tool (e.g., H3N2v – 2012)

Potency of bulk vaccine antigen lots remains >75% after 5-8 years & bulk adjuvant lots near 100% after 4-5 years

Pre-EUA packages submitted by BARDA in 2012 to FDA for stockpiled vaccines with adjuvants

Vaccine distribution through central distribution system managed by CDC


Licensure of h5n1 vaccine with adjuvant caps development initiates further partnering

Licensure of H5N1 Vaccine with Adjuvant Caps Development & Initiates Further Partnering

Milestone achievement for U.S. pandemic preparedness realized with licensure of H5N1 vaccine with adjuvant

USG (CDC, FDA, BARDA, DoD, & others) and flu vaccine manufacturers will continue partnering on post-licensure activities for seasonal and H5N1 flu vaccines.

seasonal flu vaccine safety & performance tracking

planning future U.S. tracking systems for influenza vaccine safety and effectiveness

executing these tracking systems during inter-pandemic periods and influenza pandemics
