Funny I should stumble into this question right after I read this article:
http://healthimpactnews.com/2014/cd...uenza-outbreak-on-fully-vaccinated-navy-ship/
I am a regular reader of a health newsletter that emphasizes nutritional supplements. It is written by a doctor who strongly suggests NOT taking the flu shot. His main reasons are that the flu shots contain small amounts of unwanted and potentially dangerous substances (mercury, aluminum, formaldehyde) and that they are not effective ENOUGH to warrant the risks posed by the unwanted substances the vaccine contains.
Oddly, he argues that the flu shots are least needed by young healthy people with strong immune systems and also least effective on some who need it most, the elderly, because the immune systems of the elderly are weaker and less responsive to the stimulation that the vaccine may offer. Then you have to factor in the hit-and-miss guesswork of the annual vaccine formulations that may or may not actually help protect against the strain of flu you are likely to encounter.
I stopped taking the annual vaccine at least 6 years ago while also improving my diet. Then I started adding vitamins and other nutritional supplements. I have not had any problems with the flu during this period. I have had several colds during this period, a couple of which were pretty strong ones that may or may not have been caused by the flu virus, but so far no full blown, knock-me-out cases of the flu. Knock on wood.
