i hear ya, i was not going to do any of it but figured, i get the flu shot every year, after getting it super bad many years ago, and never having a shot, i have not had the flu (not full on) since, but yes, i have heard of those with the shots still getting it. i dont know if it works, but the fact that i feel horrible, means its not sugar water, so its making me feel like crap. i guess it may help, i dont know.
