her tongue felt burned; her mouth was burning; her throat was burning; acid reflux; everything was still burning; This is a spontaneous report from a contactable consumer (patient) via Medical Information Team. A 78-years-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 MRNA VACCINE), via an unspecified route of administration on 25Feb2021 (at the age of 78-years-old) (Batch/Lot number was not reported) as 1st dose, single for COVID-19 immunization. Medical history included macular degeneration. The patient's concomitant medications were not reported. Historical vaccine included tetanus vaccine on an unspecified date for immunisation. She got her first dose of the Pfizer Covid 19 vaccine on 25Feb2021 and thought she was having a reaction. She called her doctor and he said go get some Benadryl to make sure your throat doesn't get swollen. She went out and bought Benadryl and she took the Benadryl every six hours. Her doctor said don't get the second dose of the Covid 19 vaccine because these side effects she had are a warning and the second dose might not be helpful for her. The patient reported that she stayed at the facility that gave her the Covid 19 vaccine for 20 minutes and her husband was waiting for her. When she was driving away from the facility her tongue felt burned and then her mouth was burning and then her throat was burning on an unspecified date. She does have acid reflux but this wasn't like any acid reflux she's ever had. She got home and she drank some cool water but everything was still burning. By then it was almost supper time so she took 20 mg of Pepcid. Her mouth burned throughout her meal. She called her doctor again and he asked her if her mouth was swollen and she told him she didn't know. She took more Benadryl. One of her daughter's told her that the Covid 19 virus was so bad that she should get her second dose of the Covid 19 vaccine no matter how bad her reaction was. Her doctor told her not to get the second Covid 19 vaccine. She assumed it was a done deal. She wasn't going to get the second dose. She was supposed to get her second dose on 17Mar2021. She had gone to the doctor a couple times and each time he told her, do not get the second Covid 19 vaccine. He showed her the Pfizer Covid 19 vaccine print out with side effects. When her mouth started burning after she got the first Covid 19 vaccine her husband did ask her if she wanted to turn around and go back to the facility where she got the vaccine but she told him no. Now she's missed her second Covid 19 vaccine on 17Mar2021 because she thought that what her doctor told her was the final word. She was afraid to get the second Covid 19 vaccine and she wants to listen to her doctor because he knows what's best. During this Covid 19 virus time she was also diagnosed with Macular Degeneration. That's keeping her from driving and she's lost even more of her independence. She's heard if she gets the Covid 19 virus it can attack her eyes. Every time she hears the words fully vaccinated it makes her want to cry. She's worried that people won't want to be near her because she's not fully vaccinated. Her husband had both of his Covid 19 vaccines and he had no side effects. Her husband gets every vaccine on the market and never has any side effects. As far as she's concerned she feels like a pariah because no one will want to be around her because she's not fully vaccinated. Therapeutic measures were taken as a result of all events. The outcome of the events was unknown.  Information about lot/batch number has been requested.
