The diagrams show data for a flu epidemic which hit a large country town in 1996. Figure 1 gives the number of persons who died; Figure 2 shows the percentage breakdown of females who received a new flu vaccine; and Figure 3 gives the number of cases of flu before and during the epidemic. In Figure 1 it can be seen that the flu was responsible for the deaths of 2 females but no males in the period from March to May. However, from June to August, there were 4 female deaths and 1 male death.

From Figure 3 it is clear that the new vaccine had a positive effect on the number of new cases of flu reported in females. There were just over 1000 cases reported in March, climbing rapidly to a peak of 3500 in June. Thereafter, the number of cases dropped slowly to about 2800 in August, before levelling off at 2500 for the rest of the year.
