A 49-year-old female patient received second dose of bnt162b2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, solution for injection, Lot Number: EW0202) via an unspecified route of administration at left deltoid on 19Jul2021 (at the age of 49-year-old) as dose 2, single for COVID-19 immunisation.

It was reported that caller states she was a physician who received her second dose of the Pfizer BioNTech Covid-19 Vaccine on 19Jul2021 at Pharmacy. on 19Jul2021, Patient states the injection stung more than a typical vaccine and states she "feels like it was given "more posteriorly as opposed to directly in the deltoid muscle." acromion process of her shoulder nor is it midline down, the injection site is further left. on an unspecified date in 2021, patient had "hive-like thing" at injection site, there was this huge hive. Patient states she read a short article regarding the importance of appropriate site administration for adequate vascular absorption but was unable to find recommendations or guidance in regard to whether or not she might need revaccination. Patient asking for guidance on whether or not she should get a repeat second dose. Patient asking if local and systemic side effects tend to be worse if vaccine was administered at incorrect site. Caller requested document be sent to provided email address. She was calling about the vaccine clarified she was calling about the Covid 19 vaccine. She was a physician and she got her second dose of the Covid 19 vaccine recently. She reports she had checked her Covid 19 antibodies previously and she did have Covid 19 antibodies so she believes she may have had an asymptomatic case of the Covid 19 virus at some point. She did not have the Covid 19 virus during the time she had received her Covid 19 vaccines. She had her second Covid 19 vaccine on Monday, 19Jul2021 and she could tell that it was odd that the pharmacist who gave the injection at the pharmacy gave the injection so posteriorly as opposed to in her left deltoid. She was in a rush because she had to get home to make dinner for her kid. Now she has this hive like thing on her left upper arm and it's nowhere near her left deltoid. She was concerned that she may not have received the proper amount of antibodies. The injection site was nowhere near the acromion process of her shoulder nor was it midline down, the injection site was further left and now there was this huge hive that she did not get with the first Covid 19 vaccine. She has been doing some research and woke up Tuesday, 20Jul2021 and thought she probably did not get the vaccine dose she should have gotten because it was not injected into the muscle of her arm and instead was injected in a fatty area of her arm. She could have gotten her second Covid 19 vaccine at her own institution where she works but their vaccine centre was across town and she can't get there during the hours that they are open. She was asking if she should retake the second dose. She states what complicates things more was she will be trying to get pregnant starting 01Sep2021 and she was trying have the Covid 19 vaccine completed 3 weeks prior to when she tries getting pregnant. She was asking for some guidance. She does not think her Covid 19 vaccine was given intramuscularly. She received the second Covid 19 vaccine on 19Jul2021. She reports the pharmacist wrote down on her card 18Jul2021. The pharmacist wrote the date down wrong because she got the Covid 19 vaccine after work on Monday, 19Jul2021. She further reports that she checked some medical literature regarding waiting 12 weeks in between Covid 19 vaccine doses and the literature said she could have higher antibodies by waiting 12 weeks between doses. She reports this literature was out of Britain. She waited almost exactly 12 weeks between her doses instead of the typical 3 weeks. She wanted to have higher antibodies because she will be trying to get pregnant. Patient did not visit emergency room or physician office visit for the events. Outcome of  events was unknown.  Follow-up attempts are completed. No further information is expected.
