According to this article, the government and vaccine makers are immune from lawsuits over flu vaccines.
In 1976, a massive swine flu vaccination campaign took place. Only 1 person died from the swine flu, the vaccine killed 25. Hundreds more were crippled. The government was sued for a total of $1.3 billion dollars. Now the vaccine makers and federal officials have been made immune from lawsuits. So if the vaccine has detrimental effects on you or your children, you won't be paid a single cent.
The swine flu vaccine hasn't been thoroughly tested. I'm not going to allow my children to be used as guinea pigs.
