I can understand wanting to get the flu shot especially if you or your child has a weak or compromised immune system. The question is, does it work? Flu shots are prepared nearly a year before the flu season starts and are at best a guess of what strain of flu will hit us, not to mention they may contain mercury as part of the preservative thimerosol, a known neurotoxin. The CDC will tell you it has a high percentage of effectiveness, independent research will tell you a much different story. The three flu strains that go into the vaccine are chosen nearly a year before flu season hits. Because the viruses mutate rapidly, the strains in the vaccines often donít match the actual viruses that come to your town each season. Here are some websites that explain how the flu shot is made, how effective/accurate past flu shots have been and how the "CDC crystal ball" is used to make the flu shots.
