Division of Viral ProductsMission and Functions • Regulate viral vaccines and related biological products, ensuring their safety and efficacy for human use • Facilitate the development, evaluation, and licensure of new viral vaccines that positively impact the public health
Division of Viral ProductsMajor Responsibilities • Investigational New Drug (IND) and Biologics License Application (BLA) review, and other pre-marketing activities (e.g., pre-IND) • BLA supplement review, lot release review, and other post-marketing activities (e.g., Biological product deviations) • Manufacturer inspections (pre- and post-licensure) • Consultation with other public health agencies (e.g., WHO, CDC, NIBSC) • Conduct research related to the development, manufacturing, evaluation, and testing of viral vaccines
The Role of Research in the Division of Viral Products • Research and laboratory activities complement the regulatory mission • Address issues related to regulated viral vaccines • Anticipate and address issues related to the development and evaluation of new viral vaccine products • General issues applicable to many products or product classes (e.g., cell substrate issues, improved test methods, etc.) • Specific product issues (correlates of protection necessary for efficacy evaluation, animal models necessary for animal rule implementation, etc.)
Division of Viral ProductsStaff & Budget Overview • Division Staff – FY13 • 75 FTEs • ~ 40-50 contractors (ORISE) • Postdoctoral fellows • Postbac students • Supported by targeted funds/external grants & contracts • Division Budget – FY13 • Standard operating budget ~ $2,800,000 • Targeted CBER support ~ $2,200,000 • Pandemic Influenza, Modernizing Science & Critical Path • Medical Countermeasures ~ $3,000,000 • External DVP funds ~ $3,700,000

Ph.D., Team Leader • Antigenic Structure and Function Team • Judy Beeler, M.D., Team Leader • Influenza B Viruses and Vaccine Seeds • Jerry Weir, Ph.D., Acting Team Leader
Regulatory Review Responsibilities • Product review for viral vaccines • Influenza virus vaccines • Respiratory syncytial virus • Parainfluenza virus types 1, 2 & 3 • Human metapneumoviruses • Measles, mumps, rubella, and varicella • Clinical review for viral vaccines • Vaccine lot release (protocol review) • Manufacturers inspections (pre- & post-licensure) • Participate and make presentations to the Vaccines Advisory Committee on influenza product issues and vaccine strain selection
Regulatory Review Workload • 13 scientists in LRVD have regulatory review responsibilities
Other Regulatory and Public Health Responsibilities of the Laboratory • Antigenic testing of manufacturers influenza virus seeds • Preparation of reagents for seed testing • Maintenance of influenza virus strain repository • Seasonal strains for seed testing • Candidate pandemic influenza vaccine strains • Preparation of potency reagents for testing candidate pandemic influenza vaccines • Selection and recommendation of strains for seasonal influenza vaccines • 1 of 4 WHO Essential Regulatory Laboratories • Serological analysis of vaccine responses for NH and SH vaccine selection
Other Public Health Responsibilities (Continued) • Participation in working groups and consultations with other public health agencies and vaccine stakeholders (selected examples) • WHO – Influenza guidance for pandemic preparedness; Production and control of influenza vaccine manufacturing; Improving influenza vaccine strain selection; Influenza vaccines for broad immunity • CDC ACIP – Febrile seizures & MMRV vaccination • Vaccine manufacturers associations (PhRMA, IFPMA) – Annual Influenza Vaccine Workshops
Laboratory of Respiratory Viral Diseases Research Program • Research complements and supports the regulatory mission of ensuring the safety and efficacy of respiratory viral vaccines and facilitating the development of new viral vaccines • Examples of issues addressed by the Laboratory’s research program • Development of new assays to improve vaccine evaluation • RSV neutralization • Measles neutralization • Influenza neuraminidase inhibition
Laboratory of Respiratory Viral Diseases Research Program (Continued) • Methods to improve vaccine manufacturing • Development & evaluation of vaccine candidates to improve yields of influenza A and influenza B vaccines • Evaluation of cell lines (MDCK) to improve influenza virus propagation • Influenza vaccine potency • Preparation of reagents to standardize vaccine testing • RSV serology • Influenza vaccine potency • Elucidating the correlates of protection to facilitate vaccine efficacy evaluation • RSV and influenza
Research Program Support • Each research team has received substantial support for its research program from internal (FDA) and external (non-FDA) sources • External support emphasizes the public health significance of the Laboratory’s research program • NIH Division of Microbiology and Infectious Diseases • RSV reagent preparation and serological assay development • CDC • Serological assays to evaluate immune responses to measles vaccine • Biomedical Advanced Research and Development Authority (BARDA) • Methods to expedite influenza vaccine reagent calibration • Methods to improve influenza vaccine potency measurement • Development of improved influenza vaccine strains
