The new data 'show the potential for a pre-pandemic vaccine to offer broad protection by inducing antibodies that neutralize H5N1 from more recent circulating viruses,' the group said in a statement today.
'Vaccinated volunteers developed serum antibodies that were able to neutralize diverse H5N1 viruses... (that) have caused human infections in several European countries in 2005 and 2006, and continue to cause infections in parts of South East Asia,' the group said.
'These new data reinforce conclusions of the Sanofi Pasteur phase I study published in May 2006,' it added.
