From: Vaccination against 2009 pandemic H1N1 in a population dynamical model of Vancouver, Canada: timing is everything

Figure 1

Age distribution of reported cases and comparison to model predictions. Population denominators for the given age groups were derived from 2006 census data for the GVRD [41]. a New infections in September 2009 only, b new infections in October 2009 only, c new infections in November 2009 only, and d cumulative number of infections, September 1-December 1, 2009. Vaccination began the week of October 26, 2009 and continued for 8 weeks, to obtain the actual coverage levels outlined in Table 2. The resulting epidemic curves assume R 0 of 1.4, latent period of 3 days, and infectious period of 7 days.
