Clearly there are some intelligent ppl in this thread. There are some really nasty things in those vaccines. Not just tid bits of the influenza virus, but also preservatives and known carcinogens. The problem with the flu vaccine is that there are several hundred strains of the flu virus. Also, the flu vaccine for this year is that it was developed based on the most prevalent strains from the previous year. It makes no sense to me. In all likely hood your body is way better off without the vaccine and is actually better at coping with the virus. Just my $0.02.
