Are you saying that flu shots don't trigger the same reaction from the immune system as live viruses?
It's been pretty widely accepted that, while that is the intent, it doesn't work with 100% efficacy. Also, not all vaccines are live virus vaccines, and even the live virus vaccines are specifically designed to limit the effectiveness of the virus itself.
Your first post suggests you either don't understand vaccines - or you don't agree with commonly accepted biological mechanism at play.
The issue is that, while the biological mechanism does work, it is also known that it doesn't work for the entire population, and doesn't work with 100% efficacy. IOW, getting a shot doesn't guarantee immunity by itself.
I would like to know specifically what your reasons are for not getting a flu shot. You seem to be claiming to have defensible rational reasons, so I think you should state them. This seems as good a thread as any to do that.
There are two sets of reasons, technical and philosophical. On the technical side, the flu shot is a guess at which strains it will try to protect you from. This means they may get it right, they may get it wrong. Most likely they'll get it partially right. This, by itself, reduces its potential effectiveness. Furthermore, vaccines don't have 100% effectiveness anyway on anyone, and what the level of effectiveness is depends on a number of factors. This means that if you get the vaccine, it may do something for you, it may not. What's interesting is the studies that indicate that the flu vaccine may not be effective in the age groups for which it's commonly stated need the vaccine the most.
I have issues with certain ingredients that are put in a number of vaccines. The primary one in certain flu vaccines is thimerosol (mercury). While the industry has said that the small levels of thimerosol that is placed in vaccines as a preservative don't have any negative impacts, I don't believe that's something that can be said with the level of certainty that they are stating. What I do know is that I don't want mercury in my bloodstream.
On the philosophical side, I believe that we as a society overvaccinate and overmedicate. While I do believe modern medicine is a good thing (certainly it has saved the life of loved ones, including my mother when she had her bout with cancer 14 years ago), there is a tendency to try to prevent any suffering whatsoever through pills and shots, which defies a major part of life. To me, the biggest purpose of a vaccine is trying to eradicate a disease from society, which is a noble thought. We've been successful with this for smallpox and polio. For reasons Michael has stated, we will not be successful with flu due to its mutations.
As far as big pharma is concerned, they are a necessary evil if we wish to see new medications and vaccines. However, the trend is to make new medications that improve convenience rather than actually try to prevent illnesses and death, which I have a philosophical disagreement with. The ones that we have that try to prevent illnesses and death are not seeing the level of relentless improvement that I would like to see. While I won't claim that I take philosophical argument with how many vaccines are made (although I'm sure many of you would take issue with the vaccines being produced using an aborted fetus, of which there are several), I do take issue with certain ingredients used that I don't believe are optimal, and I don't see any rush from the industry to try to find ingredients that are better suited. Because of this, I don't have any desire to support an industry that I believe is lazy and doesn't have its priorities where I'd like to see them. Consider this like not wanting to buy Lycoming parts because you disagree with their philosophy on LOP operations - it's not much different.
Our bodies do a good job at what they are supposed to do overall. So, as for me, I would rather let it do its job in the majority of cases. That doesn't mean that I refuse all vaccinations, medications, etc. I went and got my Tdap booster a few months back because we are having pertussis outbreaks here in Ohio, and someone like me who turns wrenches should have a tetanus booster. Not thrilled with the aluminum in the shot, but I considered that worth the risk/benefit.
But, I get the flu, I get sick. I don't get sick often. When I do (about once a year), it's significant enough to take me out of commission for a couple of days. It's part of life, and so I deal with it. I believe my body is better off for it, and the evidence I've seen suggests that I'm not wrong.
As I've already stated, I don't presume to tell anyone else what to do, so I get annoyed with the posts and billboards saying "Get your flu shot!" and the general implication from many that you're somehow irresponsible or uneducated if you don't. Meanwhile, there are plenty of reasons why one might choose not to. Like with everything else, one should be educated and make his or her own decision. Interestingly, most of my friends who are opting not to get a flu shot are among the more educated and more intelligent of the folks I know.
