Development of effective and immunogenic vaccines against highly pathogenic avian influenza H5N1 viruses with the potential to cause a pandemic is a public health priority. The global demand for a vaccine cannot be met in the event of an influenza pandemic because of the limited capacity to manufacture egg‐derived vaccines as well as potential problems with the availability of embryonated eggs. Thus, there is an urgent need to develop alternative, egg‐independent vaccines. We developed an adenoviral vector–based vaccine that contains hemagglutinin protein from clade 1 and clade 2 viruses, as well as conserved nucleoprotein, to broaden the vaccine coverage against H5N1 viruses.
