  1. aRelative reduction of the epidemic size, using different hypothetical pre-vaccination scenarios, in the countries of the northern hemisphere in which vaccines were available during the 2009 to 2010 winter season. The relative reduction in the epidemic size was calculated as the relative reduction of the maximum of the 95% reference range, obtained from 2,000 stochastic realizations, in the reference stochastic forecast output set.
