I was with the Canadian Military in 2009, and was ordered to get the H1N1 shot. I had an adverse reaction to the vaccine which included PERMANENT neurological, cardiovascular, gastrointestinal, and respiratory symptoms. It's difficult to believe but I now have dizziness, vertigo, irregular heart rythyms, shortness of breath, muscle weakness and pain, and numbness moving up my body, to name but a few of the serious symptoms. I went from special forces fit to that of a 70 year old in a matter of days. Please choose wisely if you do plan to have your next flu shot or vaccination. You may also ask your doctor and other Heath care workers if they will be getting these shots. My doctor flat out said "no way".
