This is a question I debate with myself every year. I have confirmed autoimmune disease that has resulted in a chronically low white-cell count. I relented and took every physicians advice to get the flu vaccine twice in my lifetime. The last flu shot I acquiested to taking, whether coincidental or not, resulted in the reactivation of shingles near my eye shortly after administration of the vaccine. I developed shingles once before when I was younger. My second bout with shingles took several months of anti-virals to resolve. Shingles is extremely painful and can result in blindness when it occurs near the eye. Since the consequences of shingles, which I have now had three recurrences of,(the last followed an extensive dental procedure on that side of my face) carry the possibility of blindness, I no longer subject my depleted immune system to the flu vaccine. I believe there are still unknowns regarding medicine and a blanket statement advising everyone to get a flu shot can carry consequences for a select group of individuals. The majority of people have no problem and it is a proven preventive for major epidemics that can result in deaths. It definitely serves a worthwhile purpose. However, there are individuals with health issues that make the flu vaccine (depending on factors related to its composition from year to year) detrimental to their state of health. I have the feeling that it is easier, since the majority of the population benefits from the flu vaccine, to exert authority in preserving the good of the majority by issuing a "no holds barred" blanket statement. Ultimately, those with pre-existing, debilitating conditions must educate themselves and make their decision based upon their known state of health.
