Clinical course reported as follow: during the call with a mother about her 18-year-old's adverse events following her 2nd dose of the Pfizer COVID-19 Vaccine she stated that she was never given any information on the vaccine to read in regards to possible side effects. She stated that when she herself got the vaccine they did not give her any papers to read, other than giving the vaccine facility her information there was no additional paperwork provided. She stated that "we would have still taken the vaccine with everything going on with COVID. However, I don't' know about my daughter since she's' young and otherwise healthy." Mother stated she did not "think they gave us any information. I went with her." The caller stated that the patient experienced some chest pain, and she could feel her heart beating hard; these symptoms then resolved. Now, a couple of weeks later while playing basketball with her trainer she experienced chest pain, throbbing on the left side of her neck, and she could feel her heart beating like palpitations. This lasted might be less than 1 min and then calmed down, but it did get to the point that she felt as though she needed to tell someone because it was really hurting. Caller's daughter was a basketball player and practices basketball intensely. When her daughter received the Covid-19 vaccine she had just finished training with the university she'll be going to. She experienced chest pain on the day she received her second Covid-19 vaccine. Today, 19Jul2021, her daughter was practicing basketball pretty hard, and her heart was beating hard and she started having chest pain and up the left side of her neck was throbbing. This was something that her daughter had not experienced before. Her daughter was going back to college next month and she'll be going through hard basketball practices and she did not want anything to happen to her daughter because of the vaccine. Because she has experienced this, she was asking would her daughter be safe practicing basketball. The patient's mother was worried if something like this would happen again to her and she fears that if she (patient) was not telling the coach and then something happening to her. Caller wanted to know if this had been reported or if these symptoms were related to the COVID-19 Vaccine and was this something she had to be concerned about. Caller would like to know if Myocarditis or Pericarditis was something that anybody who took the 2nd vaccine could have. Further, noted that during her practice, she got really tired. She stated that her chest was hurting minor, like minor chest pain and she could feel her neck throbbing and her heart beating. She was never had this problem before. She felt fine right now. Earlier she was laying down and she would have some chest pain at times. She could not feel her heart beating fast anymore. The episode lasted about less than a minute then it calmed down, but it got to the point where it was really hurting, and she was going to say something, but it slowed down. It was not hurting as bad, and it did not last a long time. The outcome of the events was considered as resolved, on an unspecified date in Jun2021.   Information on the Batch/Lot number has been requested.
