A 64-years-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 MRNA VACCINE), Batch/lot number: EL1284, Expiry Apr2021, intramuscularly on 30Dec2020 02:15 (Dose 1), right arm as a single dose (age at vaccination 64 years old) for COVID-19 immunization.  Medical history included allergy (usually in the fall she has allergy problems).  Her age is considered high risk, works in medical profession (Surgical Tech). Concomitant medication included levocetirizine (Walgreen's generic) 5mg, tablet, by mouth, at night for allergy. The patient had the first dose of the vaccine last 30Dec(2020) and after 2 days (on 01Jan2021) she developed symptoms: Sore arms, severe sore throats, back ache/ back was sore, temperature was up / low grade temp (never high), coughing, body aches. Her back and her legs were sore. Her whole body was achy. It was "like flu-ish kinda." She also had a headache. She started getting the sore throat and headache on 01Jan2021, and she felt a little cold on 02Jan2021. On 02Jan(2021), her first temperature was 100.5 degrees Fahrenheit. She states she had everything except for the GI issues. Around 02Jan(2021) or 03Jan(2021), her symptoms were progressively getting worse. She was told to get COVID tested. There were three exposures since Christmas Eve. So, she went and got a rapid COVID test (04Jan2021) and it came back negative. They also sent out a test that day. She was also tested for Strep (04Jan2021) too because her throat was so sore. It was almost like she had like thrush along with it. She states it was almost like a thrush because she had like a white tongue (onset 03Jan2021). Her throat was so sore, but it was a different kind of sore throat compared to a sore throat she has had before. She explains where the nasopharynx was at the top, it's almost like it was sore from there. It was sore to swallow, it was "a bizarre sore throat." She clarified she noticed the "thrushy" part of her throat around 03Jan2021. The strep test ended up being negative but she believes she had thrush because she was given medication and the medication was clearing that up. However, she still had the symptoms. Because her symptoms only started a few days before, they thought she should maybe wait a couple of days and if she is not feeling any better, she should be retested (for COVID). She went back again yesterday (07Jan2021). She had another Rapid COVID test and also a flu swab and both tests came back negative. She mentions they also did another COVID test (the send out type) and she should get that back around 1pm to find out the results of that.  They also did a CBC (07Jan2021) and everything was normal. Her white count was at 7. She was waiting for the 3rd COVID test result today (08Jan2021).  She reported that about three days afterwards, she didn't notice the soreness in /her arm. Her throat has improved. Her fever was down to 98 degrees Fahrenheit yesterday (07Jan2021). She states she was feeling better today (08Jan2021). She commented "the lethargy, though." She emptied the dishwasher yesterday (07Jan2021) and had to sit down after emptying it. She states her symptoms have her a little worried. She recovered from the sore arms in Jan2021. The patient was recovering from  the severe sore throat, back ache, low grade temp, coughing, body aches/ whole body was achy, believes she had thrush, white tongue, legs were sore, headache, and felt a little cold. The outcome of the event lethargy was not recovered. She was wondering if this was a reaction to the vaccine.
