The image depicts a line graph of "Cases of whooping cough (Britain) 1940-1990," showing reported cases on the primary vertical axis and percent vaccine uptake on the secondary vertical axis, plotted against years on the horizontal axis. Cases start at 60,000 in 1940, peaking at over 160,000 in 1941, a steady decline to under 20,000 in 1957, with cyclical peaks every 3-4 years never surpassing 120,000. A sharp decline occurs after the "Vaccination begins" point in 1957, reaching below 5,000 in 1968 and maintaining a pattern of fluctuation with smaller peaks. Percent vaccine uptake shows a pattern starting at 30% in 1962, rising to 81% by 1973, with a decline to near 30% in 1978, and a steady increase to 94% by 1990.

The graph depicts data about Britian, showcasing the cure effect of vaccination on a childhood illness whooping cough, for five decades between 1940 to 1990. The units of children are reported in thousands and the data of vaccination uptake by children by vaccination are given in percentages.
Overall, high fluctuations are recorded between the years, in 1941 the reported cases showed a high trend of 170000 patients, then the trend move steadily until 1953 show a high trend of approximately 165000 patients, after the vaccination begins in 1956 the graph shows an downward trend, in 1967 vacination is kept up to 81% and the suddenly decreased to 30% in 1975, in effect the cough tend increased, after 1975 the vaccination ratio steadily increased and in 2005 to 2010 it at highest rate of 94% taken by children.
Additionally, the data of cough cases and vaccination shows inverse relation with each other when the vaccination is highly taken the number of patients decreased.
