Flu Shots are not Effective with Excess Weight

While the flu season is around the corner, it is always better to take necessary precautions rather than to be unnecessarily ill. The same has been suggested by the Centers for Disease Control and Prevention. But, as every individual is different from each other, the same goes for the effectiveness of the antidote that is being injected into the body. Scientists have realized that flu shots are less effective to the people who have excessive weight or obese. While two-thirds of the entire United States adult population is overweight, it is a much severe issue than expected.

The researchers are studying vigorously about the cause of such ineffectiveness along with developing a better flu vaccine, which will work for the majority of the population. This particular phenomenon came into light with the 2009 flu outbreak, which affected the majority of the population being overweight. In the case of the obese body, the virus tends to spread faster than anticipated. And that is what exactly causes the flu vaccine to work less effectively in the first place. Another interesting fact that has come up is that the flu sheds the body at least a day later on an average for the overweight people. In other words, it seems like the virus enjoys the obese body.

While our immune system is mainly comprised of two defense systems, one including the antibodies which generally manufactures the proteins to fight off the virus, and the later are cells that join the fight with the antibodies. But, in the case of obese people, while their body can generate an adequate amount of antibodies, it is the T-cells that fails to involve in the fight. Older people have the same problem with regard to the production of the antibodies. In a nutshell, all we can do is take care of ourselves, try to shred as much fat as possible so that the flu shots can be the most effective in our bodies.
