Development of Novel Strategies to Induce and Monitor Humoral and Cellular
Immunity to Protect Hosts From Infection by Respiratory Viruses
LEIDEN, The Netherlands, September 11 /PRNewswire/ -- A new and promising research project of Top Institute Pharma is being conducted by a multi-member Dutch consortium with expertise in the fields of virology, immunology and vaccine development. The aim of the project is to develop novel strategies to induce and monitor the humoral and cellular immunity that protects the host from respiratory virus infections. This project has a budget of almost 4 million Euros. One of its aims is to reduce the risk of a pandemic outbreak of influenza, that may emerge from the current avian influenza threat to humans. The partners in the project are Solvay Pharmaceuticals B.V., Nobilon International B.V., OctoPlus N.V., ViroClinics B.V., Virosome Biologicals B.V., the Erasmus University Medical Center Rotterdam, Leiden University, the University Medical Center Groningen, Utrecht University and the Netherlands Vaccine Institute.
The project is an initiative of Top Institute Pharma, a public-private partnership that was founded in 2006. TI Pharma forms consortia of industrial and academic research teams who conduct ground-breaking, cross-disciplinary research. Its personnel are trained in improving the efficiency of the entire drug discovery and development process. Each year, the Dutch government provides 30 million Euros in funding for the top institute. The pharmaceutical industry and academia each contribute an additional 15 million Euros annually. TI Pharma is aiming to become an international leader in research, training and education.
Professor Ab Osterhaus, principal investigator: "This is a unique project, because it combines the expertise and knowledge from the fields of virology, immunology and vaccine development of prominent industrial partners, knowledge institutes, medical centers and universities. Therefore, we hope for ground-breaking results."
Respiratory viruses are the cause of a large burden of disease in humans and although effective vaccines exist to protect against seasonal influenza, no vaccines are currently available for other important human respiratory viral diseases such as avian influenza, pandemic influenza and respiratory syncytial virus (RSV) infection. There are a number of reasons for this: an incomplete understanding of the correlates of (vaccine-induced) protection against these infections that stems from research activities whose focus is too limited, inadequate research tools, and because efficient vaccine delivery systems for humans are largely lacking.
Principal investigator Professor Osterhaus: "This project aims to fill these knowledge gaps in the prevention of respiratory virus infections through developing a set of tools to enable us to better understand the roles of both the humoral and the cellular arms of the adaptive immune system, stimulated by virus infection and vaccination. Other aims of the project are to develop novel vaccines based on antigens produced by new manufacturing systems and with innovative delivery systems, that will induce both humoral and cellular immunity. Pandemic influenza will be used as the primary model disease as it is considered a major threat and is part of the World Health Organization's Priority Medicines program. Certain aspects of the work will be extended to the development of intervention strategies for RSV infection."
Most seasonal influenza vaccines are inactivated, subunit, whole- or split-virus vaccines. Vaccines for the highly pathogenic avian influenza (HPAI) strain H5N1, which may well be the basis of the next pandemic in humans, have been modelled on such seasonal vaccines but have been proven to be poorly immunogenic in humans as large doses are required to obtain a modest and highly restricted immune response. This is likely because seasonal vaccination acts to boost existing immunity, while the immune systems of the general population are naive to the H5N1 virus. Professor Osterhaus: "Given these results, and the insufficient manufacturing capacity for influenza vaccines in general, it is imperative to develop a novel generation of vaccines that will enable an increase in manufacturing capacity, enhanced immunoprotection and vaccination requiring less injections, allowing maximum protection worldwide."
