I will discuss evidence that influenza A virus antigens to which humans are initially exposed as kids dramatically shape the severity of future infections. Profound protection is apparent even against "novel" hemagglutinin subtypes, but apparently only if they are matched to the phylogenetic group of the initial infection. This provides a framework for predicting both the age distribution of future cases and the potential of successful emergence into humans of new flu strains from animal reservoirs.
