She did not want to get the vaccine. The patient stated that she does not feel good. Caller asks if the vaccine causes cancer. Caller asks if the vaccine causes infertility, she never got COVID during the pandemic. Was told the risk of the Delta variant was so bad, the risk of the vaccine outweighs the risk of the delta. Not sure if she buys that. Had it before the vaccine and now she was having it again, but more. She keeps thinking about what she just did. Began feeling sick within a few hours after receiving the COVID-19 Vaccine. Started feeling nauseous. Head was slightly hurting in addition. Was having a real sore arm, which she had a shot so she thought it might be that. Arm was more sore than the Flu shot and feeling out of it, in a daze, slightly sick, can't really think. Experiencing heart palpitations, and she was a heart patient. Would have been nice to know. She was pressured into the COVID-19 Vaccine. She never wanted it. Is extremely tired. Didn't sleep good last night. Doesn't know if it was because she was worrying about the COVID-19 vaccine. Is having anxiety. Spoke with the pharmacy. Pharmacist basically told her she did the wrong thing and was still feeling sick. Had a headache. Still feels out of it. Back and chest muscles ache. All symptoms began yesterday, 10Aug2021, within a few hours of the vaccine. Symptoms are still occurring. She just needs a nap, and she is tired. Doesn't like she just got this entire vaccine. With the first dose, everyone told her they don't get symptoms or if they do, they are very mild. Highly doubts she will be coming back for second dose in 17-35 days. Clarified her sore arm was in the injection arm only and still sore today. At first, her entire arm was hurting and felt stuff radiating in that entire arm and felt something twitching. Outcome of the events Malaise, anxiety, sleep disorder, was unknown, while for other events was not recovered.  Follow-up attempts are completed. No further information is expected.
