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

The given graph provides information on

vaccination

impact related to whooping cough incidence or a childhood illness over a span of one-half century from 1940 to 1940 in the United Kingdom.

Overall

, there is evidence that both

vaccination

and case trends were related to each other.

While

the

vaccination

started rising, the

cases

decreased significantly. In 1940, the number of reported

cases

was high which stood at slightly below 60000

cases

, increasing to its nadir up to around 170000 in the following years before decreasing to just over 60000 in 1945. These numbers kept rising at approximately 168000 until

vaccination

was involved between 1955 to 1960. Regarding

vaccination

, as can be seen from the graph, 81% of vaccine uptake was distributed, remaining stable dose until around 1977 which resulted in a significant decrease of nearly 8 times.

Furthermore

,

while

the vaccine uptake was just 30%, the

cases

ascended up to about 60000 but dropped when the

vaccination

program was applied, around 94%

at the end

of the period, showing stable trends of just less than about 100

cases

.
