Abstract (en)
[origin: WO9605294A1] Method for preparing purified influenzal antigens from a liquid containing the influenzal virus, comprising the steps of concentration, purification, fragmentation and optionally inactivation, characterized in that: A. <u>either</u> the purification step comprises a plurality of ultracentifugation steps separated by a filtration step, B. <u>or</u> the fragmentation step is carried out on the living virus in the presence of a non ionic amphiphilic detergent followed by the removal of undesirable substances by filtration retaining all of the viral constituents, <u>or</u> the method is carried out according to these two steps in any order.
