The caller stated that he had a strong reaction to the Covid 19 vaccine. Pretty much had all the side effects besides a fever, but he was in pretty bad shape for a couple of days. He had the Covid 19 virus in Dec2020, 3 months prior to the Covid 19 vaccine and from his understanding, from what he's read in reports out of Europe that the first Covid 19 vaccine acts like a booster, more like how the second shot does.  He is asking if he does need to get the second vaccine. Wondering what the recommendations are for patients who have already had the Covid virus previously, in terms of getting the second dose of the product. Caller clarified his side effects as a dead arm, really dead arm, he couldn't barely lift his arm. On 10Mar2021, that evening, of the same day he received the Covid 19 vaccine, the side effects hit him, he had diarrhea, nausea, joint swelling in hands and knees, body aches, a headache, and chills. He did not have a fever. Kind of everything else and those symptoms lingered. It was worse the first night. He still had symptoms on the second day. By 3rd day, he was pretty much in the clear. He also reports swollen lymph nodes in armpit on the left side, the side he got the vaccine on. Caller reports that there was nothing out of the ordinary at the injection site, no itching, redness, swelling or irritation. He also reports an elevated heart rate. He's had an elevated heart rate since he had the Covid virus. The night of the Covid 19 vaccine, his heart had skyrocketed. He tracks his heartrate overnight with an apple watch and it's at 87 beats per minute, which would have been a resting heart rate that was really out of the ordinary. He reports 87 beats per minute is high for him. He got up to go to the bathroom and his heartrate was 120 beats per minute and that was just going to the bathroom. 120 beats per minute is more like a workout. Caller states that he has had bowel issues, prior to getting the vaccine, so he is not sure if the diarrhea is related to vaccine or not. He was taking antibiotics for Lyme disease. He doesn't think that his Lyme disease helped him with the Covid 19 virus. Caller states that he takes things for his immune system, supplement wise. He went hiking, he got bit by a tick. He had heard about Lyme disease but didn't take it seriously enough at the enough. Caller tries to warn other people now to make sure they are taking the preventative precautions. Caller doesn't want to suffer getting the second vaccine if he doesn't have to, and he doesn't want to take a dose away from someone else if they need it. He doesn't want the government to punish him for not getting the second shot. Like not allowing him to take an airplane. He is asking if he does need to get the second vaccine. The patient did not receive any other vaccines within 4 weeks prior to the COVID vaccine. Prior to vaccination, the patient did not experience any adverse events. Dosage text: left arm, into muscle of arm. Had Covid 19 virus in Dec2020 and did not want to get it again.  No follow-up attempts are possible. No further information is expected.
