Virologist Frederick Hayden of the University of Virginia in Charlottesville says that although he does not know the particulars of this case, he thinks in general that the flu immunizations could do some good. Although the shots are not effective at treating the illness, they could protect the seven tribespeople from future exposure to flu. Moreover, Hayden notes that early treatment with influenza antiviral medications, such as Tamiflu or Relenza, could “shorten the duration of illness and reduce risk of lower respiratory tract infections.”
