Back aches; Chills; Couldn't breathe; Couldn't walk; pain; This is a spontaneous report from a contactable consumer (patient). A 84-years-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE), via an unspecified route of administration, administered in Arm Right on 20Feb2021 16:30 at 84-years-old (Batch/Lot Number: EL9264) as dose 2, single for COVID-19 immunization. Medical history included ongoing Thyroid issue, ongoing High blood pressure, Lung carcinoma cell type unspecified stage I (Lung cancer stage I, She hasn't had treatment for over a year. She had radiation.) Concomitant medications included levothyroxine taken for Thyroid issue from an unspecified start date and ongoing; losartan taken for High blood pressure from an unspecified start date and ongoing; aspirin [acetylsalicylic acid] taken for an unspecified indication from an unspecified start date and ongoing. The patient previously took first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Lot Number: EL9265), on right arm on 30Jan2021 at 84-years-old for COVID-19 Immunization. Patient had both Pfizer Covid Shots. She had side effects and had to be rushed to the hospital. They are sending her a bill, and she felt that she should not have to pay the hospital bill. Her insurance paid so much and the bill is for $250 that she doesn't have. It is for the ambulance. The vaccine was for Covid. She had the first dose on 30Jan2021 and the second on 20Feb2021. 2 days after the second one she had to be rushed to the hospital. She was getting chills, back aches, and all kinds of complications. She couldn't even move, and she called an ambulance. Her insurance left her with a $250 bill. She called the ambulance to say it is due to the Covid shot. Each time she called she waited over an hour. Yesterday she waited over an hour and a half. She is a little disgusted. Now she got a bill from the hospital, and she figured it was related to the Covid shot. She thinks they gave her a shot at the hospital. It was quite an experience. After she was admitted to the hospital for a couple hours that Saturday or Sunday so she thinks she was in the hospital on 21Feb2021, they gave her a shot and she started seeing things. It was an experience she doesn't want to go through again. She has no idea what the shot was, she thinks it was for the pain. They sent her home and gave her pills to take for the pain. She doesn't want to take too many pills for pain. The pills are Hydrocodone Acetaminophen, she takes one half to 1 tablet as needed for pain for up to 3 days. They are in an amber colored pharmacy bottle. It says OTY6. She couldn't walk 2 days after she had the second shot (22Feb2021). Back aches: She more of less ignored it. She took Tylenol and that didn't help. That Sunday she more or less started aching and couldn't breathe. She told her husband she had to get out of there. She just took regular Tylenol, expiration date: Nov2023. She does not see a lot number. Each one is 500mg. She has arthritis too. It is an over the counter medication. Couldn't breathe 2 days after she had the second shot. As a matter of fact, they had to lift her off of the bed. It was on and off for a couple of hours. She can't remember if she had any tests done. Adverse Event Chills, couldn't breathe, couldn't walk, and back aches time of onset (24-hour clock) was about 13:00 or 14:00. She did not take any other vaccinations within four weeks prior to the first administration date of the suspect vaccine. She asked the doctor before taking the vaccine, and he said it wouldn't affect her at all. On the paper it specifies if she has any side effect to call the ambulance which she did. She cannot get them on the phone and waited over an hour. The outcome of the events was unknown.  No follow-up attempts are possible. No further information expected.
