In June 1996, an experimental flu vaccine was trialled in a large country town on females only. The result of this survey is presented in the following illustration.

The illustration outlines the outcome of a flu vaccine trial among females in a big town in June 1996. Overall, the experimental flu vaccine was not effective in terms of its result on females. The diagrams reveal that flue rate was generally higher among women than that of men in 1996. From April 1996 to June 1996, the infected people’s number increased swiftly and more female became vulnerable to the flu than that of men. At the beginning of June, the number of male patients was somewhat 2500 compared to 3500 females at which point the injection was tested among women. Though it might seem that the flu contamination among female decreased afterwards, the overall flu rate among males gives a different scenario. During August until the end of the year, around 2500 females were recorded to have flue while this number was a thousand fewer for males. Interestingly, only 1 female died from flu during March to May 1996, but after the vaccination, the death case rose – 4 female and 2 male death cases were recorded between June and August. Finally, almost a quarter of female child and 35% elder females were at risk despite the immunization. 13% needed medical attention while just over a quarter who did not receive the injection were also at risk.
