According to a new study, the flu shot that so many people rely on, may not be as beneficial for them as they think. This fact is particularly true for elders in society, and according to epidemiologist Dr Tom
Jefferson, the cost and effort that is necessary to manufacture and carry out vaccinations needs to be looked at very carefully.

According to Jefferson: "The large gap between policy and what the data tell us is surprising. The reasons for this situation are not clear and may be complex. The starting point is the potential confusion between influenza and influenza-like illness, when any case of illness resembling influenza is seen as real influenza, especially during peak periods of activity. Some surveillance systems report cases of influenza-like illness as influenza without further explanation. This confusion leads to a gross overestimation of the impact of influenza, unrealistic expectations of the performance of vaccines, and spurious certainty of our ability to predict viral circulation and impact. The consequences are seen in the impractical advice given by public bodies on thresholds of the incidence of influenza-like illness at which influenza specific interventions (antivirals) should be used. Reasons for this are not clear but may stem from the confusion between influenza and influenza like illness, the acute respiratory infection which looks like influenza but is not, a lack of accurate and fast surveillance systems, and the fact that vaccines are available."

Due to the fact that every year brings a new strain of flu, scientists have a hard time pinpointing it so that a workable vaccine can be manufactured in time to vaccinate people from contracting it. Because of this fact, there is not a huge difference in the amount of people that die from flu, compared to the amount of people that die from the flu even after being vaccinated against it.
