The graph shows the impact of vaccinations on the incidence of whooping cough, a childhood illness, between 1940 and 1990 in Britain.

The graph illustrates how the

number

of reported

cases

of whooping cough in Britain changed throughout the period of 1940-1990, depending on the introduction of

vaccination

.

Overall

, the trend showed a strong correlation between an increase in

vaccination

popularity and a slump in the

number

of disease

cases

. A closer look allows us to notice high morbidity during the first 15 years since 1940, with a maximum of roughly 175 thousand

cases

, and its steady decline since the

vaccination

began. A noticeable drop continued until the 1980s when Britain experienced a surge in the

number

of

cases

of whooping cough aligned with a considerable fall in the rate of vaccine uptake, which amounted to a minimum of 30 per cent. Afterwards,

although

fluctuating at the beginning, the

number

of

cases

dropped to 0 by the end of the 1990s as the rate of vaccine intake reached its peak of 94 per cent. By and large, the chart provides feasible statistics that strongly support the effectiveness of

vaccination

in fighting against a certain disease.
