Additional information: Caller received his first dose of the Pfizer Covid 19 Vaccine in Jan2021 with a normal reaction of headache, napping 4 hours daily about 4-5 days. The second vaccine was in Feb2021, second shot scared the heck out of me. The caller experienced a more intense headache, seemed to magnify his arthritis about 10-fold, tired aching like he ran a 5K, lower back pain, quad pain, calf pain, and lower back spasms. His daughters took the Moderna with no reactions. He has friends asking if he heard about the 2 guys who died with a heart attack. Caller continues to have the pain in the quads. The hospital would like for him to take the booster Pfizer Vaccine. Caller asking if any reaction have been reported with the Pfizer Covid 19 Vaccine? The CDC states that reactions reported after getting the Pfizer-BioNTech booster shot were like that of the 2-shot primary series. Fatigue and pain at the injection site were the most reported side effects, and overall, most side effects were mild to moderate. However, as with the 2-shot primary series, serious side effects are rare, but may occur. Per caller about 40-50 of all injection mostly come from dead virus of the virus. Caller asking how the Pfizer Covid 19 Vaccine was developed? He said that he called a nurse about the second shot. He said that the 2nd shot was of great concern to him. He is 75 years old, has type 2 diabetes, a slight amount of arthritis in his hands and pelvis, and he has neuropathy. He said that he had agent withheld in withheld that caused his neuropathy. With the second shot, the headaches were more intense. The arthritis seems to be magnified 10-fold and he had trouble walking. He went to do his normal walking routine and found himself leaning forward on his cart and his hands hurt. He realized after about a month of blaming it on arthritis, it was more like muscle pain in his quads, lower back, and calf muscles. The pain was the worst in the quads. He had spasms in his lower back. The spasms subsided and the pain in the calf's kind of went away. The thigh pain is still there. He said that also in the morning, he felt a warming feeling in the top of his head for 7-10 days. He said that he did not have a fever. He went into the get the Flu shot at the withheld recently and said that he had a warming feeling for 24 hours. No further details provided. The availability of the booster shot just came available. He said anyone of 65 years or older or if you have a compromised immune system is eligible. He knows he is eligible to get the booster shot. If this thigh pain does not subside, he does not want the booster. Could it possibly amplify the pain? The shot itself it was not an antivirus. It is a chemical compound, correct? Caller said that he received many vaccines in the past including polio vaccine and vaccines when he went into the (private). He said that the malaria vaccine was a doozy. No further details provided. Caller declined to complete a report. The caller requested to be transferred to operator to have his questions addressed as he did not have much time because he had someone coming to his house.   Follow-up attempts completed. No further information is expected.
