So lets see, they want the whole country to take a flu shot because the flu kills about 400 seniors a year and about 60 people under 65. (read first section of site below for math)  A flu shot that works less than 50%(links 8 to 11 at site below).  or often much less, for something you only get about every 10 to 15 years.(Links 16 and 16a). Most people who think they have the flu, do not, it is the rhinovirus or stomach flu, something the flu shot does not work on.(Link 16c).
    They are now realizing that if you take a flu shot every year, it pretty much stops working or can make you more likely to get the flu.(Links 19 to 27)  Your chance of a serious adverse event from the flu shot is about 5 to 10 in a million, your chance of dying from the flu is about 2 in a million if your under 65.

I am a senior, I do not want young people getting a flu shot to give me some minor protection. Young people are much more important than us old farts.
