I came across an article about this vaccine, written by an independent, unbiased drug policy researcher. The drug company that makes this vaccine has been marketing it very heavily - big bucks involved! It is a very expensive vaccine. After going through the drug company information with a fine tooth comb, his conclusion was that only 1 person out of 35 will benefit from it, plus there is a 1 in 7 chance that you will suffer severe side effects.
Obviously everyone must make their own decision as to whether this is worth it. However, since my ME was triggered by a tetanus shot, I have decided to never have any more shots of any kind.
