ABSTRACT
This contribution is a wide-ranging comment on the three preceding chapters. Written in early January 2010, it proposes some reflections generated by these three papers concerning the ethical stakes in pandemics in general, and on influenza in particular. Whether they consider events dating to almost a century ago (the problems of quarantine during the pandemic of 1918) or more recently (the subject of avian influenza), the three chapters concern questions that remain entirely debatable today.
