I have been experiencing constant chills, reflux laryngitis is it STDs or flu shot side effects?

I am a 20 year old female. I have the same and first sexual partner for almost 4 years now. We performed oral and he ejaculated in my mouth when I had burning in one tooth gum. Now I have been experiencing constant chills & sometimes night sweats for almost 2 weeks. I have reflux laryngitis that I am currently dealing with as well. But I also took an influenza seasonal vaccine a week before. Could this be HIV or side affect of the flu shot or laryngitis?
