Vaccines are a vital part of society’s arsenal for preventing the spread of infectious diseases. Since they are challenging to produce, vaccine manufacturing is largely concentrated in select locations in the developed world. This situation presents steep obstacles to transporting them to people in the developing world who need them the most. Moreover, transportation and […]

Diphtheria is still a disease causing significant morbidity and mortality in people worldwide that did not received vaccination or suffer from incomplete immunization. The disease is due to a powerful toxin produced by the pathogenic bacterium Corynebacterium diphtheria. A good vaccine already exists but its production is rather complex and involves several steps: cultivation of […]

Vaccines are one of the most important medical breakthroughs, proactively saving millions of lifes and reducing human morbidity. Yet there remains a need to make current vaccine formulations more effective and affordable, which requires testing and optimizing new formulations. In addition, there remains diseases for which there are no efficient vaccine. To develop and test […]

As an analytical platform, the Sanofi Pasteur Analytical Sciences (Toronto) Molecular Biology Centre (MBC) is applying and optimizing the use of high-throughput sequencing (HTS). The detection of adventitious viruses in biological products relies on a set of methods defined by the regulatory agencies called the compendial methods. High-throughput sequencing has the potential to improve the […]

Sanofi-Pasteur is developing new vaccine formulations that need to be evaluated on their efficacy and potency. Traditionally, the use of animal models to predict human immunity has been accepted as the best way to select vaccine formulations. However, animal models can be costly and time-prohibitive, and the assays employed to assess vaccine efficacy and potency […]

Monitoring the immuno-modulatory effects of vaccine formulations is critical for novel vaccine development. While animal models have been effective, increasing evidence suggests differences when translating to humans. We have designed a platform which uses fresh human whole blood coupled with a high-throughput single cell analysis, mass cytometry (CyTof Helios), to characterize and model the immune […]

Pertussis, caused by the strict human pathogen B. pertussis or Bordetella parapertussis, is a highly contagious, potentially life-threatening respiratory tract illness when it occurs in unprotected infants. Despite the introduction of acellular pertussis (aP) vaccines and great initial success of the immunization program, pertussis outbreaks were reported in adolescents and adults in Canada since 1993. […]

The therapeutic effect of a vaccine depends on its chemical composition, and in particular the integrity of its protein components. Conditions under which a vaccine is manufactured and stored can damage the proteins it contains; however, since proteins are structurally complex and reactive, their degradation during routine handling is unpredictable. In the project described here, […]

Manufacturing of consistently high quality products is the commitment of the pharmaceutical industry. To achieve this, new products must be thoroughly tested and the results meet government-approved product specifications. Improving existing and adopting improved analytical technologies for product testing ensure the production of safe and effective products. This is particularly critical for the manufacturing of […]

Vaccination remains the most effective preventative measure for influenza infection. Seasonal influenza epidemics and the emergence of pandemic strains have increased the global demand for influenza vaccines, putting significant pressure on vaccine manufacturers. However, current vaccine manufacturing strategies rely primarily upon production in eggs, an age-old method that needs to be significantly improved. Recently, research […]

The way a vaccine performs after injection is not completely understood and not all vaccines behave in the same way. To make a vaccine we must understand what is important or critical to make it work. For example a vaccine may have specific features such as its size or shape that are critical to the […]
