The problem with AA's "link" is that it leads to the New York Times' "sign in" page.
As for the flu shot, I've never had one and I don't see a need to get one this year. I'm healthy and there are a lot of people who need it more than I do.
I have had the flu shot for...umm...I think 4 years now...this year will be my 5th...never had any complications and have seen people around me fall sick with the nastiest of nasty flus and i'v ebeen fine.
