Earl Zablackis, Director And Principal Scientist, Sanofi Pasteur

Dr. Zablackis is a classically trained Botanist and Marine Biologist having earned two bachelor degrees from the University of California, Berkeley (1979) and a Masters degree from the University of Hawai’i (1985). He completed his PhD in Cell Biology at the University of California, Santa Barbara (1991).

He has spent 30+ years studying polysaccharides in academia an industry, first completing post-doctoral work focused on plant cell wall polysaccharide isolation, purification and structural characterization using a broad range of analytical techniques (HPAEC-PAD, GC, GC-MS, multiple MS platforms and NMR) at the CNRS in France and Complex Carbohydrate Research Center at the University of Georgia (1997); and secondly in the pharmaceutical industry where he joined Bayer Biologics in 1997 as a senior scientist managing the carbohydrate chemistry lab developing and validating analytical methods for recombinant glycoproteins and monoclonal antibodies. He joined Aventis Pasteur in 2000 as an expert in analytical carbohydrate chemistry and method validation. He is currently a Director-Principal Scientist in Global Analytical Sciences at Sanofi Pasteur (the vaccines unit of Sanofi).

Dr. Zablackis serves as a member of the PDA Biopharmaceutical Advisory Board and is the liaison to the PDA Vaccine Interest Group. Additionally, Dr. Zablackis is a member of the USP Expert Committee for Biological Analysis (GCBA) serving as chair of the vaccine subcommittee.


Pre-congress Workshops, April 6 @ 10:00


Analytical methods that ensure identity, purity, and potency of vaccines have continued to improve but are primarily used for characterization rather than release testing. USP Biologics will gather stakeholders to learn about novel methods and to discuss opportunities to advance these methods in both pharmaceutical QClabs as well as global control laboratories. The workshop will include talks as well as an expert panel to debate these topics and address questions from the audience.Workshop leader opening remarks: Dr Maura C. Kibbey, Senior Scientific Fellow, Education & Training, Global Biologics, USPPresenations topics include:
  • Use of NMR assays for characterization of polysaccharide-based vaccines
  • Opportunities and challenges of in vitro potency development for FSME Immun release and stability testing
  • A regulatory perspective on NGS for adventitious virus detection in biologics
  • Strategies and Examples for vaccine development and lifecycle management

Pre-congress Workshops, April 6 @ 2:00


  • Molecular size, from distribution coefficient to multiple measured characteristics using light scattering-not as easy as you would think
  • Use of NMR assays for characterization of polysaccharide-based vaccines
  • A regulatory perspective on NGS for adventitious virus detection in biologics
  • Panel with all speakers
