Flu shot didn't work for older folks?

It seems logical to me that the same people concerned about Social Security expenses and Medicare might also have done something to reduce costs which is basically (Make the flu shots not work that great). So, how would anyone do this? There would be a variety of ways at every point in the manufacture or storage of flu shots. The easiest way someone could have done this is either by microwaving the shots or by irradiating the shots at any point. Or it could have been done if they were not refrigerated properly. So, it is important for me to say that any one along the way could have made the shots ineffective in any sort of way or ways. So, maybe out of 10,000 people or more involved in making the shots had to do something really small and untraceble to end it's effectiveness. So, I do not think anything like this could be traced likely. But, as a result many more older people and children and people of every age died than should have this year both in the U.S. and around the world. So, basically the flu shots this year didn't work.
