The patient previously took first dose of BNT162B2 for COVID-19 immunization on 07Jan2021. It was reported that she received her second dose of the Pfizer COVID vaccine on Friday, 29Jan2021. she knows the vaccine is supposed to be administered in the deltoid muscle. However, she thinks her vaccine was administered subcutaneously, when her colleague administered the vaccine she pinched her skin and she did not feel the injection like she did the first dose and she the thinks the needle may have slipped out the muscle and the following day she felt itchiness, noticed her arm had a 2x2 inch raised area that is hot and firm. Patient stated it is one inch away from the injection site and her arm was not sore like it was with the first dose. Patient would like to know if there is any information regarding if the 95% efficacy applies to the Pfizer COVID vaccine if the vaccine is not given intramuscularly. she works as part of COVID vaccination team and goes to long term nursing facilities. She would like to know if she needs a third dose if her second dose was given subcutaneously instead of intramuscularly. It was reported that she spoke to her primary care physician and he suggested that she should have antibody testing done to check her immune response to the Pfizer COVID vaccine. She would like to know if this recommendation is correct. She would like to know if there have been any other reports of allergic reactions like her report of raised firm area one inch away from injection site. It was reported that Caller states one Pfizer COVID vaccine dose contains 30 mcg. Caller states she saw in one of the studies that 100 mcg was the max dosage that could be given. Caller would like to know if the 100 mcg is the max dosage per dose or the max dosage for the entire series. She says that the following day she felt itchiness, and on Sunday she looked at her arm and there was kind of like a lump, not too raised, but two inches by two inches in diameter that was firm, hot, and red. She says this wasn't at the injection site, which was one inch away. She says she is still going to be working with patients in long term care facilities and would like to know it will be effective. It was reported that she kept the site clean, and she didn't take Benadryl or anything, it was a slight itch, and she didn't want to disrupt anything. Reporter considered it was not serious. The outcome of events was unknown.  Follow-up attempts are completed. No further information is expected.
