The two graphs compare the information about the impact of vaccinations on the incidence of whooping sickness in Britain for 5 decades.
It is evident that by starting the vaccination in 1955, the number of reported cases decreased sharply and after the decrement of vaccination in the 1970s, the number of sick people suddenly grow up. It is predicted that this disease will be eliminated and the number of reported cases will be zero in 2010.
The blue figure shows that before the beginning of vaccination, the number of reported cases was considerably high and it was in a maximum situation in 1940. After 1940 the number of reported cases increased gradually and reached the minimum peak in 1945, but then the numbers started to increase sharply and the figure shows its peak. More than 170, 000 people were reported of illness. While, this number was reported before, in 1940.
After the vaccination begins, the number of sick people considerably decreased. About 81 percent of people were vaccinated in 1970 so the number of sick people was about 20, 000 and by decreasing the number of vaccinated people to 30 percent, the number of reported cases increased suddenly in 1980.
