Development of a vaccine effective against avian influenza H5N1 infection in humans

摘要

The WHO influenza pandemic preparedness plan, issued in 1999, sets out a series of steps to be taken following confirmation of human infection with a new influenza virus subtype not yet spreading from person to person. One of these steps concerns theinitiation of research needed for vaccine production. As a precautionary measure, WHO is moving forward with the procedures needed to rapidly produce a new influenza vaccine capable of protecting humans against the H5N1 strain of avian influenza recently detected in Viet Nam. These procedures have been initiated following mounting concern over 5 laboratory confirmed human cases of H5N1 avian influenza in Hanoi, Viet Nam in recent weeks. All 5 cases were fatal.
