A 56-years-old female patient received booster dose of bnt162b2 (COMIRNATY; formulation: solution for injection, Batch/Lot number and expiry date were not reported), via an unspecified route of administration on an unspecified date as dose 3 (booster), single (at the age of 56-years-old) for COVID-19 immunization. The patient's medical history and concomitant medications were not reported. The patient did not have COVID-19 before. The patient's historical vaccine included first dose of bnt162b2 (COMIRNATY; formulation: solution for injection, Batch/Lot number and expiry date were not reported), via an unspecified route of administration on an unspecified date as dose 1, single; second dose of bnt162b2 (COMIRNATY; formulation: solution for injection, Batch/Lot number and expiry date were not reported), via an unspecified route of administration on an unspecified date as dose 2, single, both for COVID-19 immunization and experienced no adverse effect; D-tap vaccine via an unspecified route of administration, on an unspecified date in 2018 (at the age of 53-years-old) for immunization and experienced heart condition within 36 hours to 14 day and allergic reaction. The patient reported of not having any reaction for first dose, for second dose, the patient felt like a B12 shot and felt great. However, after receiving the booster dose of the Pfizer BioNTech COVID- 9 vaccine, the patient had multiple symptoms. The patient when received the primary vaccination series, did not see any additives like polyethylene glycol in the vaccine. But then the patient read the disclaimer after the booster shot. The patient called the pharmacy to ask whether the vaccine COMIRNATY and Pfizer COVID-19 vaccine were interchangeable. The patient did not want the COMIRNATY vaccine because it had many additives. The patient thought that was the reason of having this reaction to the booster dose of the Pfizer COVID-19 vaccine. The pharmacist had no clue about the COMIRNATY vaccine and did not know what the patient was talking about. The patient was so scared and was traveling with grandmother and elderly mother. The patient do have a mildly irregular heartbeat. The patient was just scared. The patient reported of having a reaction after receiving the tetanus Sanofi Pasteur D-tap vaccine in 2018 and was lucky the patient was even alive. The patient had a heart condition within 36 hours to 14 days. The patient was in and out from the cardiologist office and had a Holter monitor and 14 days after it stopped. It was some sort of allergic reaction. The patient was scared about going to end up with a heart attack or a stroke and concerned because the patient have an irregular heartbeat and the D-tap vaccine made the patient feel this way. After receiving the Pfizer BioNTech COVID-19 booster dose which the patient received earlier because the patient was traveling, the patient had a giant cold sore on 15Nov2021 (on the day of report), and it was easing up but the reaction the patient had over the past two days was concerning. On an unspecified date, the gland under the patient right arm was massive. It looked like it was bruised all swollen and felt like someone was cutting with a razor blade, the lymph gland under the arm of shot. The patient had a broad spectrum neurological like nerve ending pain under fingernails and toenails and every joint and feel like neuralgia on an unspecified date. The patient felt nauseous and fatigue on an unspecified date. But the patient was worried about the swelling in the gland, thought it was going to burst. It was so painful. On the day of report, it was better. Motrin helped a lot. On an unspecified date, the patient was sick and had a crazy reaction to the booster dose of the vaccine. The doctor told the patient to keep taking Motrin and it should resolve on its own. The patient was feeling better on the day of reporting, the gland was still painful, but it has gone down. The nausea dialed back. Therapeutic measures were taken as a result of the event lymph node, so painful. The outcome of the events had a giant cold sore today, and lymph node, so painful was recovering; outcome of all the other events was unknown.  The lot number for the vaccine, COMIRNATY, was not provided and will be requested during follow up.  Follow-up: This follow-up is being submitted to notify that the lot/batch number is not available despite the follow-up attempts made. Follow-up attempts completed. No further information is expected.
