headache; Fever was reported as worsened.; low grade fever; allergic reaction redness, warmth and itching at the injection site; allergic reaction redness, warmth and itching at the injection site; nodule/ bump; allergic reaction redness, warmth and itching at the injection site; nausea; This is a spontaneous report received from a contactable Nurse (patient) via medical information team. A 56-year-old female received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Solution for injection, Lot Number: ER8727), via an unspecified route of administration, administered in Arm Right on 22Apr2021 at 10:00 (at the age of 56-year-old) as single dose for covid-19 immunization. Medical history included hair dye, allergy vaccines. The patient's concomitant medications were not reported. The patient previously took polyethylene glycol 3350. The patient experienced allergic reaction redness, warmth and itching at the injection site on 24Apr2021, nodule/ bump on 24Apr2021, low grade fever on 26Apr2021, headache on an unspecified date, nausea on 23Apr2021, fever was reported as worsened on an unspecified date. The events were reported non-serious. Patient stated she had delayed reactions, 3 days after the vaccine. She experienced "allergic reaction redness, warmth and itching at the injection site, a nodule/ bump, low grade fever, headache, nausea". She said she is allergic to the hair dye and she feels similar to after taking the vaccine. It could be due to the PEG in it. Patient stated that she was having symptoms that began on day 4 after the vaccine, a red circle around the vaccine site, it's warm and there is a hard knot under the skin. She still has a fever this morning and nausea, bad headache. She stated my concern was the amount of itching right at the site which reminded me of a true allergy not just a side effect.  She experienced the same as when she was young.  She had allergy vaccines and would react the same.  The reaction she had is the same as with this vaccine reaction. She had a bad reaction to hair dye, and I started reading about the ingredient PEG that is sometimes found in that. The ingredient Polyethylene glycol, she had a question asked about the ingredient before the vaccine, she stated I guess that's in the diluent, and she never thought about the bad reaction she had to hair dye.  When she put it together, and she understands it is in the vaccine. She was screened before the vaccine and she did have a pretty good reaction to hair dye at the end of last year. Her reaction started 2-3 days ago. Today, the redness is pretty much gone and the itching is gone, but it is still itching slightly. Confirmed that red circles, itching, and warm hard not started on 24th.  Her fever was a little bit higher today, but still low grade. She stated when looking at her vaccine card that she may be wrong when it started after. She stated it would have been about 3 days ago so the 25th when the symptoms started. History of all previous immunization with the Pfizer vaccine considered as suspect was none. No additional vaccines administered on same date of the Pfizer Suspect. The adverse events required to go to Emergency Room and Physician Office. The patient did not receive any other vaccines within 4 weeks prior to the COVID vaccine. The outcome of the events allergic reaction redness at the injection site was recovered on 27Apr2021, events allergic reaction warmth and itching at the injection site, nodule/ bump was recovering, events low grade fever and Nausea was not recovered while for the events headache and Fever was reported as worsened was unknown.
