Band 6+: The graph shows the impact of vaccinations on the incidence of whooping cough, a childhood illness, between 1940 and 1990 in Britain. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The graph illustrates how vaccinations affect the incidence of whooping cough which is a childhood illness in Britain from 1940 to 1990.

Overall, it is evident that the incidence of whooping cough fluctuated before the introduction of vaccines. After that, the whooping cough rate dropped sharly while the popularity of vaccines increased over time despite a drop early on.

In 1940, the figure for whooping cough started at 50000 cases, after which it experienced a significant increase to reach a peak of 170000 cases in 1943.Following that, the number of cases rebounded to levels similar to those at the initial stage. However, with the introduction of vaccinations, the number of cough cases decreased dramatically from 1960 to early 1970.

In early 1980, while vaccinations started to decrease which fell to 30%, the incidence of whooping cough was resurgent, at about 60000 cases. This was followed by a steady decline as vaccines was reintroduced from late 1980 and onwards. At the end of the period, vaccines grew sharpy to reach a peak of 94% which was equivalent to the gradual drop to nearly 0 cases in the figure for this disease.
