A British study shows that people who are suffering from diabetes that also take up the flu vaccine have a lower risk of being hospitalized for respiratory or cardiovascular problems.
One significant consequence of this fact is that the flu vaccine may reduce severe illness and even death, which could be a sufficient reason to recommend it to people with diabetes.
The research had been conducted at the Imperial College of London, where the scientists analyzed seven years monitoring of 125,000 people with type 2 diabetes.
When they looked into the individuals who received a flu vaccination, the percentage for hospital admission in cases of stroke dropped 30%. Heart failure hospitalization decreased by 22%, and the rates for pneumonia and influenza went down with 15%.
The most interesting part is that the flu vaccine had positive effects on hospitalizations that were not directly related to the disease. The connection exists because flu can also provoke heart attacks and strokes.
Flu complications appear especially in elderly people suffering from heart disease, asthma, or diabetes. Therefore, they are more vulnerable to the disease, and a vaccine protects them from complex medical conditions.
The researchers also verified other factors that may influence hospitalization rates, such as other medical conditions, weight, age, smoking status or gender.
The scientists also compared the summer months with the flu season, so the study managed to explore a lot of different scenarios before issuing a conclusion.
The statistics go further showing that patients who got the flu vaccine had 24% lower death rates.
The heart attack hospitalizations were also somewhat lower, but not in a significant percentage.
One of the limitations of the study is that some of the people who were considered to be healthy might have had undiagnosed diabetes, which could have to trigger an error in the statistics.
A second factor that may affect the results of the research is the fact that people who did got the vaccine were also healthier from other points of view, even if still diabetic.
Taking the entirety of negative and the positive aspects into consideration, the study continues to show that vaccination does have an effect on people who have diabetes, and they can feel the benefits of being protected against the virus and its complications, which can be very dangerous for individuals with an underlying medical condition.
The authors of the study recommend people with chronic diseases to prevent the flu complications by getting the vaccine and avoiding the flu in the first place.
