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.
