Skin irritation; Fatigue; Heaviness in the chest; Green phlegm; Sore arm; Body Aches; Nausea; Headache; Fever; Chills; This is a spontaneous report from a contactable consumer (patient). A 42-year-old male patient received second dose of bnt162b2 (BNT162B2, solution for injection, Batch/Lot Number: EW0170), via an unspecified route of administration, administered in Arm Left on 25Apr2021 as DOSE 2, SINGLE for covid-19 immunisation (age at vaccination 42 years). The patient medical history and concomitant medications were not reported. The patient previously received first dose of bnt162b2 (BNT162B2, solution for injection, Batch/Lot Number: EP7533), via an unspecified route of administration, administered in Arm Left on 04Apr2021 at 13:00 as DOSE 1, SINGLE for covid-19 immunisation and had sore arm. The patient experienced, fever, chills, headache, body aches nausea on 26Apr2021, heaviness in the chest, green phlegm, skin irritation, fatigue, sore arm on an unspecified date.  It was reported that, the patient experienced recurring side effect for 2 weeks, fever, chills, skin irritation, fatigue, headache. They resolved and then 5 days later, it came back, not as severe. A few days later back again. they came and go but less severe. He stated with first dose he had just the sore arm. Caller wanted to know about reports of reoccurring side effects. The experience was unusual with the Pfizer vaccine. The only side effect he experienced was a sore arm.  He thought that was typical. 10 days later he began feeling heaviness in his chest, he had no cough, but had phlegm that was green in the morning. He had no cough, no fever, chills or loss of taste.  He felt fine, until the second shot. He experienced his sore arm after he had the 1st shot on 04Apr2021.  It occurred that day or night and lasted 24 hours, probably not that long. The heaviness in the chest he has been with him since about 15Apr2021, and has kind of decreased.  He was not short of breath, had no cough, just green phlegm. He never experienced phlegm without a cough or congestion, but it went away before the 2nd shot, but started to come back after the 2nd shot. Caller added what is unusual about the situation is the side effects the 2nd time around with the 2nd shot, the side effects come and have gone, but are recurrent. The strongest side effect after the 2nd shot was the day after the 2nd shot. They went away and then about five days later they came back. Caller added basically 25Apr2021 was when he got the second shot. On 26Apr2021, he experienced the worse day of side effects, then it went away and came back 5 days later and went away, then 3-4 days later came back and went away again. His symptoms were not as severe as the day after the 2nd shot. The symptoms have come back 2 times, but less severe, but noticeable. His day was done and he would lay down and have to deal with it. He experienced the green phlegm in the morning after breakfast with coffee, and as he was getting ready for day.  He did not experience later in the day. Like with a chest cold. He could cough in the morning and then it was out of his system. On that 2nd day, he experienced the most significant of symptoms. He had a sore arm again, that lasted 24 hours, but had definitely fever, chills, headache, body aches and nausea. Caller added these last 5 symptoms, are the ones really recurring and spaced out. Caller added it is ok though. He read about it. However, thinks these strange. Caller added as he understands it ongoing means continuous. Whereas, his symptoms lasted a day, went away, came back with decreasing severity, but were still noticeable. The outcome of fever, body aches, chills, headache, nausea was not recovered. The outcome of sore arm was recovered, on an unspecified date in 2021, other events was unknown.  No follow-up attempts are needed. No further information is expected.
