A 61-year-old male patient received the second dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection, lot number: EK9231, expiry date: not reported), via an unspecified route of administration, on 28Jan2021 09:00 AM at a single dose on the left arm for COVID-19 immunization. The vaccine was administered at a hospital. It was not administered at a military facility. He did not receive any other vaccines within 4 weeks prior to receiving bnt162b2. The patient had no relevant medical history and concomitant medications to report.The patient previously received the first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, lot number: EK9231, expiry date: not reported, NDC number: 59267-1000-1), on 09Jan2021 09:30 AM on the left arm for COVID-19 immunization, at the age of 61-year-old. He experienced myalgia at the injection site/pain at inject site after the first dose on 09Jan2021 and resolved on 12Jan2021. The first and second doses of bnt162b2 had the same lot number. On 28Jan2021, the patient received the second dose of bnt162b2. 24 hours later, on 29Jan2021, he experienced mild aches/pain, nausea/malaise. Three days (42-72hours) after 2nd dose, on 31Jan2021, he experienced "significant redness" and swelling at injection site with minimal pain. He described it as "Out of proportion to what should be expected". The redness and swelling were improving at the time of the report (01Feb2021).  He asked if this should be of concern. He also asked if it was possible that the vaccine was given subcutaneously instead of intramuscularly. He developed a good amount of swelling and redness at the injection site. It seemed fine the first day. It took two or more days to develop the swelling. He added that he only had mild myalgia, weakness, and nausea initially on 29Jan2021 after the second dose of the vaccine. Then 48 hours later, he got the large amount of swelling and redness at the injection site. He later clarified he received the first dose of the Pfizer COVID 19 vaccine on 9Jan2021 at 09:30 AM in the left arm. He had some myalgia at the injection site on 09Jan2021 that went away on 12Jan2021. Then he received the second dose of the Pfizer COVID 19 vaccine on 28Jan2021 at 09:00 AM in the left arm. Initially he had no pain. 24 hours later, on 29Jan2021, he had myalgia referring to general muscle pain and aches and nausea that only lasted about two hours. He is mostly concerned now about the significant swelling and redness at the injection site with minimal pain which he noticed 48 to 72 hours after the second dose of the vaccine. He took some Aleve which gave some relief (for significant swelling and redness at the injection site with minimal pain). He asked if this is an expected side effect as it seem out of proportion to him. Outcome of events general muscle pain and aches and weakness was recovered on 30Jan2021. Outcome of event nausea was recovered on 29Jan2021. Outcome of events significant swelling and redness at the injection site with minimal pain was recovering.
