He developed a few dark spots on his left arm where he got the shot; On his right arm near the elbow, occasional soreness/right arm joint is tender every once in a while; Gets purple spots on his left arm; Occasional soreness.; This is a spontaneous report via a Pfizer sponsored program Inbound Call Center for HCPs from a contactable consumer (patient). A male patient of an unspecified age received bnt162b2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Solution for injection, Batch/Lot number was not reported) via an unspecified route of administration on an unspecified date in Mar2021 as dose 2, single for COVID-19 immunisation. The patient medical history and concomitant medications were not reported. Historical vaccine includes bnt162b2 via an unspecified route of administration on 28Feb2021 as dose 1, single for COVID-19 immunisation. On an unknown date in Mar2021 the patient developed a few dark spots on his left arm where he got the shot, on his right arm near the elbow, occasional soreness. It was reported that he received the first dose of the vaccine in February and got or was exposed to Covid to someone with the Covid in-between the first and second dose. He then tested negative. He got the second dose after testing negative. Now, he periodically gets purple spots on his left arm and right arm joint is tender occasionally, and he wanted to make sure or know if that is part of it. He also wanted to make sure he is fully vaccinated after being exposed to the virus. It was the first week and he had a customer he was near but they both had masks on. He got tested one week later. He just had a part of one weekend where he felt a little like he was coming down with something. He was not hungry and was tired. Caller thought he better get tested to make sure he did not have it so that he would not give it to a customer or anyone. He tested negative. He then got the second shot, and then he found out after the second shot literally the same day that if people got the second shot they should not wait or if they did get it, they should wait three months and does not clarify statement and wondering if that will effect it. He was negative so he does not know if he had it or not. A couple of weeks later, he developed a few dark spots on his left arm where he got the shot. It was on his mid forearm between the forearm and the wrist, on top. And then it would go away and he would get more, it would be different, darker to lighter. It always goes away, he does not have any currently. He does not know if this has anything to do with anything. And asked if he can speak with medical information as he has to go quickly and he did not really want to report anything other than that he did not experienced anything. He is glad he got it. He is thankful for the first shot since he was possibly exposed. He never really developed symptoms and he was testing himself regularly like his temperature. His first vaccine was 28Feb2021 and then three weeks later was the second, but he does not have his card. The patient underwent lab tests and procedures which included covid-19 test resulted as negative on unspecified date in 2021, covid-19 test resulted as negative on Mar2021 (he got the second dose after testing negative). The outcome of the events was unknown.  Information on the lot/batch number has been requested.
