A 70 -year-old female patient received her  first dose of BNT162b2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, lot number: EM9810), via an unspecified route of administration (on left arm) on 15Feb2021 (at the age of 70 -years-old), single dose for COVID-19 immunization. Medical history included asthma, sleep apnea, thyroid problem, prediabetes, cpap use, all from an unknown date. There were no concomitant medications. Patient reported her face is blood red. Last night her chest was hurting radiating to my arm down. It felt like someone was strangling her with water. She noticed my symptoms were what people experience after receiving the second dose. She had fever, chills, exhausted and just felt very tired after receiving the first dose. She still have trouble breathing. She had severe asthma. She was not breathing normally. When she put the mask on it's even harder to breath. She was worried. She thinks, she might have the coronavirus. Consumer says that she is still not feeling well after receiving her first dose of the Pfizer COVID-19 vaccine on February 15th. She says that the first day after getting it, she had pain in her arm, it was achy, it was not really painful enough to where she had to take Tylenol for it. She says yesterday on the second day she had fever, chills, tiredness, general malaise, and today she is not feeling well. Caller says she was having trouble breathing, and did a treatment with her nebulizer which she has because she has real bad asthma. She says her breathing is labored and she wheezes every once in a while. She says she would like to see if there is anything that she needs to do, because she works with children, and if she is coming down with the corona virus she doesn't want to be around them with it. She says that her breathing is problematic today. She says she doesn't think that she is having a severe reaction, she has no rash or those kind of symptoms. She says it seems to be just the asthma, and last night she drank some water and choked on it then couldn't get her breath and her chest hurt and she had pain down her arm and thought oh gosh she was having a heart attack.Caller says she has done no treatments other than the nebulizer treatment. No further details provided about the nebulizer treatment. Caller says the provider said no Tylenol right away, so she didn't take any yesterday with her fever, and she didn't have a thermometer to take her temperature, but her face was really hot and she was having chills, which usually means she has a fever. She says that her arm that was sore was the one where she had her injection. She says that never really was that bad, everyone said their arm had ached, and she has a high pain threshold so it never bothered her. Her wheezing and little trouble breathing was better, after she did some breathing treatments with the nebulizer, she is not breathing well but she is breathing better. She says she is also shaky and doesn't know if that is just nerves, or if this is also something going on. Caller says that it has been a while since she had blood work, which was the last time she went to see physician, but she doesn't know the results for what they found out. The outcome of the events Breathing difficult,wheeze was recovering, other events was unknown.
