Well I haven't had one either, but the serum they use now does not have the flu virus in it, like the early ones did.
Thing is, the shot only protects against one strain, usually the most prevalent one, so it's easy to still get the flu after you had a shot, and then it's only natural to blame it on taking the shot.
If someone gives me the flu, I'll rub my staph infected skin on them!
Really though, if it's out there my grandson is going to bring it home!
