A 70-years-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection. Lot Number: EN6202), dose 2 via an unspecified route of administration, administered in left arm on 26Feb2021 at 13:44 (at the age of 70-years-old) as dose 2, single for COVID-19 immunization. Medical history included psoriasis from Jan2020 and ongoing states patient was diagnosed for a while, January2020 and Thyroiditis. The patient previously took Otezla took it for a month in Dec2020. Historical vaccine included dose 1 of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Lot Number: EL9264) as 1st single dose administered in left arm, high up on the shoulder on 05Feb2021 at 12.07PM (at the age of 70-years-old) patient experienced fatigue. Patient had regular COVID-19 antibody tests in the past and they were negative. Patient did not clarify if those other tests were before or after her vaccines. History of all previous immunization with the Pfizer vaccine considered as suspect (or patient age at first and subsequent immunizations if dates of birth or immunizations are not available) reported as no. No additional Vaccines Administered on Same Date of the Pfizer Suspect. No prior vaccinations (within 4 weeks) If applicable, list any other vaccinations within four weeks prior to the first administration date of the suspect vaccine. Adverse event following prior vaccinations was no. Family Medical History Relevant to adverse event caller states her sister has Psoriasis, and she was also getting a Spike Protein antibody test. Her sister had a lot more reactions to the Pfizer COVID-19 vaccine. Caller states her sister lymph nodes were swollen for weeks. Patient take thyroid pills and take medication so its ok. And patient also had psoriasis, but patient do not take any medicine for it sometime patient use a cream but patient was not taking any medicine for it. On 24May2021 it was reported that, Patient had second dose from Pfizer on 26Feb and when it went into arms it burned and it hurt and it was really painful. But patient just, slept a lot that night and arm did not get sore anything. Patient did not had any headache anything but patient went for spike Protein Antibody test and its only at 91. So, patient think have very low because patient know people have it and they have it in thousands and patient only have 91. It started been a couple of month patient did not know it was the second shot something went wrong and never had pain with the first one patient could not even feel the first one. But the second spike was 91 then patient started well patient know that well. Patient was just wondering do patient need a booster now because something was not been covering. Caller would like to know Pfizer's stance on getting a booster dose for vaccine. Has Pfizer provided a statement on the need for a booster dose (3rd dose). Is Pfizer investigating the need for a booster dose. Patient confirmed the date of spike protein antibody test 17May2021. Patient did not have any bad effect the only thing that was bothering me was it hurts, the second time when they put in arm it burnt. It's just because when they put it in the whole thing burn patient tell like there was something wrong. First one patient did not feel at all and the second one it really hurt. On 25May2021, Patient had the first dose on 05Feb2021, and patient did not feel the injection and the second dose on 26Feb2021, and it patient felt burning as the vaccine was injected into arm patient screamed out in pain, but only felt it during the injection. Patient felt fatigue for a few days, after both vaccines and patient was usually fatigued, but it felt more than usual. Patient went to get a Spike Protein antibody test, and reports result as 91. Patient think this result was very low, and patient has read that people have this result in the 1000's after a couple of months, after having the vaccine. Patient has done research, and results are at least 10 times higher, than result, as it can go up into the thousands. Patient has concerned that, result of blood test was low, and patient will not have any protection because patient lives in. Patient reported, seriousness for felt burning as the vaccine was injected into her arm, after second vaccine and fatigue, after the first and second vaccine was reported as unspecified. The patient underwent lab tests and procedures which included antibody test: negative antibody test: 91 on 17May2021 at 3:44. Patient visited to Emergency Room/Physician Office reported as no. The patient did not take any treatment for the events. The outcome of the event burning sensation was recovered on 26Feb2021 and event fatigue was recovering while rest of the events were unknown.   Information on Lot/Batch number was available. Additional information has been requested.
