Swelling; Itchy; This is a spontaneous report from a contactable consumer (patient herself). A 70-years-old female patient received the second dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, Lot number: EL9263; Expiry date: unknown), via an unspecified route of administration, administered in left arm on 04Feb2021 11:30 (age at vaccination: 70 years) as a single dose for COVID-19 immunisation. The patients medical history included hypothyroidism, slightly high cholesterol and anxiety. After the first vaccine she really didn't have nothing to speak of maybe a little tired. Concomitant medication(s) included levothyroxine sodium (SYNTHROID), 88 mg once a day, ongoing; simvastatin taken for blood cholesterol abnormal, 40 mg once a day, ongoing; lorazepam taken for anxiety, 1 mg tablet twice a day, ongoing. After the vaccination the patient was there for 3 hours. There were no additional vaccines administered on same date of the Pfizer suspect. The patient took a flu shot in September. She was going to get Pneumonia vaccine, but she didnt because she knew this was coming down the line. She took shingles shot about a year or two ago and it was two doses. With the first dose of shingles shot she had no reaction and she even had the Pneumonia shot at the same time and had no reaction. The second shingles shot she got a month later. She had the reaction which was typical side effects. She felt achy, like flu like symptoms. She didn't know if she was coming down with the flu or having a reaction. On 07Feb2021 08:00, the patient was itchy and developed swelling. On an unknown date, the patient underwent blood test with unknown results. The patient reported that On Sunday she had an unusual reaction. She thought it was unusual because she hasn't seen it listed. With the first vaccine she really didn't have nothing to speak of maybe a little tired. She got the second one on Thursday, 04Feb2021. She didn't feel much for the first couple of days. On Sunday morning when she woke up around 8 AM, the inside of her elbow where the crease was itchy. She scratched it. That night or early evening the area she was scratching was very swollen. It wasn't red or hurt, but it was swollen. She took a shower and when she got out is when she noticed the swelling about 6:00 PM. The area opposite had swelling too. It wasn't at the injection site, but it was in the same arm. She hasn't seen that listed any place. Since Sunday night it has gotten less swollen, but she assumed it was a reaction to the vaccine. She says it has gotten better. She can't think of anything else that was really different that would cause it. She hasn't seen that listed anyplace. All she has seen listed is swelling at the site of injection. The patient reported that right above the elbow crease on the right side of the left arm was quite swollen. It was swollen and distorted. The opposite, outside part of the arm, was slightly swollen. All the swelling was on the same arm that the vaccine was given in, but it was not swollen at the injection site. The reporter stated that right above the elbow crease on the right side of the left arm was quite swollen. It was swollen and distorted. The opposite, outside part of the arm, was slightly swollen. All of the swelling was on the same arm that the vaccine was given in, but it was not swollen at the injection site. She saw her doctor every 6 months and was seen in September. She got her blood checked. There was nothing new she has taken or new foods. She had looked up COVID vaccine side effects the last three days and never saw this. She had seen COVID arm where the injection site swells up, but nothing where the mid arm does. The patient did not require emergency or physicians office visit.
