    Document: Recent findings provide new evidence that supports the role of alternative reinfection mechanisms in driving multiple-wave influenza outbreaks. Notably, a large serological survey conducted during the first wave of the 2009 H1N1 pandemic highlighted host heterogeneity in the efficient development of humoral immunity [9] . This report challenges the assumption that influenza infection confers life-long protection against reinfection by the same strain [10] . From a theoretical perspective, it is possible to fit mathematical models in which individuals can be reinfected by the same strain to multiple-wave outbreaks [11, 12] . However, these existing models are rather phenomenological and have been endowed with different biological interpretations, ranging from immune escape by antigenic drift to reinfection by immune deficiency [11, 12] .
