A female patient of an unspecified age received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE), lot number: EH9899, via an unspecified route of administration on 19Dec2020 at single dose for COVID-19 immunization. Medical history was reported as none. There were no concomitant medications. The patient stated, "I am a Registered Nurse, an RN here in (city name) and I received your Pfizer vaccine (Covid 19 Vaccine) yesterday morning. I just wanted to report some issues with the vaccine. All through the night  in Dec2020, I had the muscle pains, generalized muscle pain all over, even Tylenol (later clarified as Ibuprofen 200 mg, lot number: 9FE3019A and expiry date: Mar2021) wouldn't even work. I have a low grade temperature, headache, and real pain at the site of the injection, some chills earlier yesterday on 19Dec2020. So, I am afraid to get the next Pfizer one because to get some more side effects. This one is making me just kind of loopy too kind of light headed, and I am just really tired, really fatigue on 20Dec2020. With this Pfizer vaccine, I thought it was approved by the certain drug and (Center Name) and according to your message that I just got on another phone number has not been approved. But it was rushed out just for emergency use. Is that correct?". When informed about the role of Pfizer Medical Information and offered the number, the patient stated, "Well one number that I got, it was all loopy. I mean it was just all over the page, I couldn't leave a message. They gave me so much information that. So, which number you are talking about?". The due date for the next shot: 06Jan2021. I am a healthcare provider and I also go into the COVID unit probably in January sometimes. So, I wanted, I am kind of one of your guinea pig. "When I initially got it on 19Dec2020, of course I had pain at the injection site. I could not even turn onto my other side last night from pain at the injection site. Yesterday on 19Dec2020, I got some chills, I got a low grade temperature, feeling fatigue after a while. At first, I didn't feel that other than injections site. Through the whole night I had low grade temperature, extreme muscle and joint pain generalized, which I couldn't even sleep, I had insomnia. Tylenol wouldn't even help with that. Of course tiredness but I couldn't sleep. So I can't really feel okay, not a very good sleep yesterday. Low grade temp when I got up in the morning and dizziness and weakness this morning definitely and ringing in my ears kind of like.Yes I am generally, but the dizziness and the weakness is kind of new one. I had Tylenol during the night because I couldn't sleep, because I had such muscle and joint pain all over my joint in Dec2020." The outcome of the events was unknown.
