A 50-years-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, formulation: solution for injection, lot number: EL3249, expiry date: 31May2021) via unspecified route of administration, in left arm on 05Feb2021 10:45 (age at vaccination: 50-years) as dose 2, single for Covid-19 immunisation. Historical vaccine included BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, formulation: solution for injection, lot number: EL3249, expiry date: 31May2021) via intramuscular route, in left arm on 15Jan2021 (age at vaccination: 50-years) as dose 1, single for Covid-19 immunisation. Medical history included anxiety from an unspecified date and unknown if ongoing. Concomitant medication included ongoing Lexapro, oral, 10 mg, 1x/day [10mg, 1 tablet by mouth every day], taken for anxiety. Caller was wondering if she was having a different kind of symptom from the Pfizer Covid vaccine. She said she experienced fatigue, tiredness on 05Feb2021, aches, and pains on unspecified date. The fatigue and tiredness started within 2 hours of getting the vaccine. She had nausea here and there on 06Feb2021. The nausea didn't start until the next day of getting the vaccine and has gotten a little worse. Yesterday she had a hard time eating her lunch and a little today. However, she mentioned that she had an unusual reaction. 6 days after receiving the vaccine, on an unspecified date in Feb2021, she said she noticed a weird smell similar to that of puke and trash and nauseated. The smells has gotten worse the day after and she didn't connect it to the vaccine at first. This would last only a few minutes, up to 5 minutes and go away. It was weird, she was in parking lot and got out of car and the smell just hit her and another time was when she was inside of the house and thought her kids stepped in dog feces and brought it in the house. Her family do not smell anything and she has asked them. Again, mentioned being in the parking lot and at home and a couple other times by herself she would smell it and then it would disappear. Last night while in bed started to think that this was the opposite from those not being able to smell. Her sense of smell is off the charts, it's crazy. It would happen sparingly and go away. Last night she started to think that this may be a symptom of the vaccine. Woke this morning about 3:30am due to the smell, it hit her really hard that she felt like she was going to puke. Woke up her husband and asked him about it and no one can smell this smell. Again, after a few minutes it went away, but she had a rush of a headache and got out of bed to take Tylenol. She said it happened several times and would usually last for 3-4 minutes, followed by a headache on 11Feb2021 and nausea. She said she took Ibuprofen to treat the headache and went on to describe the smell "as if someone had dumped on a bag of trash and puked all over it." She wanted to know if this was still associated with the vaccine. The outcome of event for sleep disorder was recovering, for aches and decreased appetite it was unknown, and for the rest it was not recovered.  Follow-up attempts are completed. No further information is expected.
