You can't get sick from a vax that doesn't use live virus (aka most versions of the flu shot - dunno if she's getting the one version that isn't which I think might be the nasal one?).
The "sick" feeling you get in those instances is a stimulation of the immune system. Not full blown flu. Just putting that out there. Biochemically speaking impossible to contract the flu or any other viral disease from a vax that isn't 'live'.
