When if you get a flu shot does that protect you from developin flu like symptoms such as hiv?

Never! The flu shot protects only against the flu (influenza is the full name) and no other infections, even if those infections can cause similar ("flu-like") symptoms. I hope that you are taking precautions to protect yourself from HIV ("safe" sex at all times, avoiding anonymous sex with partners you do not know, awareness of "post-exposure" prevention and "pre-exposure " prevention, etc).
