Flu Vaccine Chart
Flu Vaccine Chart

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 is responsible for the deaths of 2 females but no males from March to May. However, from June to August, there were 4 female deaths, but only 1 male death.

According to the pie chart in Figure 2, only the females showed a high(er) risk by being given the new flu vaccine; 28% did not take the trial. Of those females who took part, 35% were aged (over 65 years old); 24% were babies or children; and 13%were hospitalised and required other medical attention.

From Figure 3 it can be seen that the new vaccine had __ positive effect on new cases of flu reported in females. There were about 1000 cases reported in March, and 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. For males, the figures were lower but showed a similar trend throughout the epidemic.
