Dr Xavier Saelens
Group Leader of the Molecular Virology Unit at Ghent University
Walter Fiers was born in Ieper, Belgium in 1931. After obtaining
a degree of Engineer for Chemistry and Agricultural Industries at
the University of Ghent (1954), he started his research career as
an enzymologist in the laboratory of Laurent Vandendriessche in
Ghent. He then worked in Copenhagen before obtaining a fellowship
from the Rockefeller Foundation and joining molecular biologist
Bob Sinsheimer's group at the California Institute of Technology
(CalTech) as a post-doc in 1960.
Dr. Xavier Saelens, born in 1965, obtained a Bachelor's degree
in Biology from Ghent University in 1985, where he later obtained
a Master's degree in Biotechnology and a PhD in Biotechnology. He
is currently a Lecturer in Virology and Group Leader of the Molecular
Virology Unit at Ghent University. His current work surrounds the
development and characterisation of novel influenza A and B vaccines.
A major part of the research is focused on the characterisation
and optimisation of an M2e-based vaccine. In particular the mechanism
of action and the performance of M2e-based vaccines in animal models
other than the mouse are unresolved questions that remain to be
This two-year cooperative research project, called Universal Vaccine,
began in October 2005 and has received ‚1.2 million in funding
under the Sixth Framework Programme of the European Commission.
The unique combination of the three SMEs for the rational design
of a mucosal influenza vaccine is unprecedented in European vaccine
research. If the universal vaccine proves successful in clinical
trials, it will not only help to diminish the social and economic
costs of influenza, but also secure the growth and development of
the European vaccine industry in the global market.
Dr. Saelens considers the Universal Vaccine program a key element
in the battle against human/avian flu for one simple reason. Whereas
other vaccines work by stimulating the body's immunity against the
haemagglutinin (H) and neuraminidase (N) proteins on the virus'
surface, the Universal Vaccine focuses on the M2 protein in the
virus' outer coat. And while the H and N proteins are prone to mutation,
with few exceptions, no change in the amino acid sequence of the
M2 protein has been reported since influenza virus was first isolated
in 1933. If this protein could stimulate an adequate immune response
it might be possible to develop a broad-spectrum vaccine against
all influenza A subtypes. Dr. Saelens is also excited at the prospect
of helping to produce a vaccine that can be administered nasally.
By stimulating the immune system at the site of influenza virus
entry into the host, nasal vaccination may help to induce more effective
and long lasting immunity in recipients. Furthermore, needle-free
nasal sprays are safer and easier to administer, reduce the risk
of contamination ‚ and are far less likely to deter people
from participating in vaccination programmes.
