Figure 4From: Vaccination against 2009 pandemic H1N1 in a population dynamical model of Vancouver, Canada: timing is everything Impact of timing on the effectiveness of different vaccination strategies. Vaccination campaigns were implemented weekly, starting July 5, 2009, with the last campaign started November 22, 2009. For a given campaign start date, the reduction in a final attack rates and b mortality relative to no vaccination was assessed using actual (blue, solid line), uniform (green, dashed line), parents and children only (red, dash-dotted line), or parents and children only/actual sequence (cyan, dotted line) vaccination strategies. All simulations assumed R 0 of 1.4, latent period of 3 days, infectious period of 7 days and an 8-week vaccine roll-out period.Back to article page
