sore arm; This is a spontaneous report from a contactable consumer (patient) via medical information team. A 71-years-old female patient received second dose bnt162b2 (PFIZER-BIONTECH COVID-19 MRNA VACCINE, formulation: solution for injection, #lot: EL9266), via an unspecified route of administration, administered in Arm Left on 27Feb2021 (at the age of 71-years-old) as single dose for covid-19 immunisation. Medical history included dry eye, seasonal allergy, food allergy, she had a food allergy to eggs, which was not diagnosed, it started with her childhood doctor who basically said that if she got a rash each time, she ate eggs, to stop eating eggs and multiple allergies. The historical vaccine given was first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 MRNA VACCINE, formulation: solution for injection, #lot: EL3247) via an unspecified route of administration, administered in Arm Left on 25Jan2021 as single dose for covid-19 immunisation. The patient said that she discovered her allergy to Amoxil because she had severe itching when she took it back in 1984. She said that they didn't test everything for every allergy back then. She says that she has a food allergy to eggs, which wasn't diagnosed, it started with her childhood doctor who basically said that if she gets a rash each time, she is eating eggs, to stop eating eggs. She said that after her first vaccine dose she woke up second day a little tired and continued to feel a little tired through the day, which did not cause her to go to bed or anything, she just did everything slower. Concomitant medications included krill oil, ascorbic acid, borago officinalis oil, fish oil, magnesium, nicotinamide, pyridoxine, zinc (OMEGA-3 & -6 COMPLEX) and calcium carbonate, colecalciferol (VITAMIN D 2000) at 2000 iU, once daily. No further details provided about any of these medications. The patient received her second dose of Pfizer-Biontech Covid19 vaccine on day 33 instead of the scheduled day 21. The patient called as she had concern about second Pfizer COVID-19 vaccine shot, who siad she received it pretty late, it was delayed due to weather and she was supposed to have her second dose on 15Feb2021, and she had it on 27Feb2021. She said it had been 72 hours, and she did not have any reaction, other than the sore arm for 24 hours, and nothing else, her energy level had been high. She said her question was whether the second dose was effective since the second dose had the reputation of worst adverse events than the first, of having a more powerful reaction. The patient said after both doses were given, she had a sore arm that started probably about 4 hours later, and she took Acetaminophen, that was that. She said that there was little to none for both soreness after about 24 hours, maybe a little bit more than that, with taking the Acetaminophen. She said she did not take medicines often normally, she took two doses, each time as a dose two tablets 8 hours apart. She said she actually never took the second dose of Acetaminophen on her second dose of the vaccine. She said that the Acetaminophen tablets were 650mg each as treatment. She said the second time after the second dose she cleaned closets and her garage and had no lack of energy. The patient said that her vaccine card was a pre-printed card created by CDC, and she wrote a number on there that she added that started with W44 that was on an email she got in scheduling email from the health department. She said neither dose of the vaccine had an EXP or NDC provided for it on the vaccine card. She said that the first dose LOT was EL3247, and the second dose LOT was EL9266, and both doses were given in her left arm. There was no information provided for a sample of the product available to be returned or whether packaging was sealed and intact. On an unknown date the patient experienced sore arm. Therapeutic measure was taken to treat as Acetaminophen 650mg. The outcome of the event was unknown.  No follow-up attempts are possible. No further information is expected.
