You know that I'm delighted to hear that you're doing well Toes and I sure can't speak to your personal situation and experience. Nor am I going to waste time here debating this fellow's claims. But there is more than sufficient evidence out there to demonstrate that vaccines are safe, including those for flu, unless, that is, that you really believe that hundreds of government agencies, private organizations, and whole nations including our own are all on a campaign to kill people off worldwide.
