The clinical course was reported as follows:  Consumer reported that 2 hours after receiving the first vaccine dose, she experienced headache, fever, chills, nausea, and diarrhea. Fever "went away" by Monday (22Mar2021) morning. Consumer asked, will she have the same or worse symptoms in the second dose. She is not pregnant at the time of vaccination.

AM. Resumed ADLs Tues. Prior to vaccination, the patient was diagnosed with COVID-19. No covid tested post vaccination. No other vaccine in four weeks. Her personal physician recommended she not receive second shot. There were two reasons. One was that she had COVID in early Dec2020, and she received the monoclonal antibodies. The side effects she had after first shot were robust. Based on that information, it was his medical opinion for her not to receive the second shot. She has not been able to get that opinion. Does Pfizer have any recommendation for getting second dose after having COVID and receiving monoclonal antibodies? She had the COVID prior to getting the vaccine. She was given the monoclonal antibodies on day 5 after symptoms and day 4 after the positive PCR test.   No follow-up attempts are needed; information about lot/batch number cannot be obtained.
