Additional information: The patient is a diabetic patient and noticed that the vaccine contains glucose and polyethylene glycol and is hesitant to get the 2nd dose of the vaccine because she might have some contraindications with those ingredients.

She has worked with Pfizer before with a chemo drug, they were having her report every month because they didn't know why the medicine she was taking worked for her because the protocol requirements she didn't meet that, in fact she wasn't supposed to be taking it and trying it.

Prior Vaccinations (within 4 weeks) were none. 5 minutes after receiving vaccine in the afternoon the patient had headache: It was severe, it was like on the right side of her head and it would really come and go but it was severe when it was there but it took 5 days for it to totally go away, and she doesn't usually have a headache.
