Agency states that the caller asks if these are common side effects and what should she do about getting the second dose, should she still get the second dose even after her symptoms. Caller went to the doctor already and went to the ER this past Saturday. Caller states she felt like it was a racing heart and chest pain and chest pressure. Caller states she figured it was part of the vaccine and within 24 hours 24 hours everything but the chest pressure went away. Caller states she also had pain in her chest. Caller states she wrote it off because everyone told her that she would have symptoms for 24-48 hours and she tried to steer clear of the ER. Caller asks should she never receive the second dose? Response: Read from attached FAQ-COVID-19 Vaccine-receiving second dose after side effect from first dose (v2.0). Calling about the Covid 19 Vaccine. States that she has talked to her health department about her symptom since getting her Covid 19 Vaccine 2 weeks ago and they recommended that she call and report them. She is supposed to get the 2nd dose next week. Name: States that her legal first name is withheld, but she prefers to go by withheld. She got her 1st dose on 02Sep2021, about 45 minutes to an 1 hour after the shot, she started to feel chest pressure and chest pain. The chest pain went away after about 24 hours. The chest pressure has continued to be intermittent throughout the day; it increases and decreased; fluctuates; it's just pressure, no more pain. She also has debilitating fatigue. She did go to the ER once, and she thought about going again but she didn't think she could make it out to her car. States that she's never had fatigue like that before. She knew she could always call an ambulance, but what can they do for fatigue. States that she did go to the ER once on Saturday and they did a bunch of tests, but their focus was on her chest pressure, not the brain fog and light headedness that she was also experiencing. She was told she would just have to wait out the brain fog and lightheadedness and they didn't even offer any tests for that, they just focused on her chest. They did an X-ray and an EKG, and both came back within normal range. Caller does not have the full contact information to provide for the prescribing physician. States that the brain fog and light headedness have been consistent since within 45 minutes to 1 hour after the injection. Sometimes she can't even focus on what she is reading. She is in school and has to try to focus really hard because of the intense brain fog. When she got her vaccine, the school set her up with V-check which is something on her phone that sends her questions to check on her every few days. She thinks it reports the information to the CDC, but she was told to contact Pfizer too. What does she do about getting the 2nd shot? She did have other symptoms also, like she felt like she was getting the flu, but that only lasted 24 hours so she didn't think it was important to report. She had muscle aches, no fever, but just felt like it was the onset of getting the flu; but it only last 24 hours then it went away. The fatigue was much worse last night, that's when she thought about going to the ER but didn't think she could get to her car, but today the fatigue is back to where is has been for the last 2 weeks; she can get through her day, but it's a struggle. Indication continued: States that she was hesitant to get the vaccine at first because she was worried about the side effects, especially worried about fertility since they are trying to have another baby, but since getting FDA approval and more information has come out about the vaccine she though that it was safe.  No follow-up attempts are possible. No further information is expected.
