The information on the batch/lot number for bnt162b2, bnt162b2 omi ba.4-5 has been requested and will be submitted if and when received.  Additional information:  The patient was a believer in vaccines in general. She had four Pfizer Covid vaccines so far. The second vaccination produced a strong reaction. At the reporting time, many months later she was experiencing/have experienced since Mar, some symptoms of being a long hauler.  She said she have asked her doctor of her situation but her doctor was in denial of the symptoms that she's having so she's kind of stuck. She said she has brain fog and complete lethargy, can't pick up feet to move and lasted for 36 hours can't do anything and can't think, can't say words, and can't remember words. Blood pressure was up since Mar and it's higher than normal, very sensitive to heat or humid in summer and could not go outside. She said she a very active 76-year-old. She had the 1st Pfizer shot and the booster. The booster gave her the brain fog. She had the shot at 8:00 in the morning, by 3 in the afternoon, she couldn't think or organize and was pretty much stationary at a chair that lasted for 36 hours. And then went away and then she was doing her income tax. Those were the reactions that she's had. To her knowledge, she has not had Covid, was not tested positive. So, she went ahead with the next dose round and got the next 2 Pfizer Bivalent. She didn't have any reactions for the 1st one on Jan, Feb and it was early Mar that her adverse reactions started. She's thinking her immune system was all screwed up because she had all that stress. She said she had 2 friends who are experiencing the same, 1 was a long hauler for 3 years now. So, she's asking for somebody's gut feel at Pfizer for a recommendation if she needs to take the new 2023-2024 formula. She said she's scared to death that she might be a long hauler. She said she needs an educated guess so she could make a decision for herself. She wanted to know what reactions other people had on the vaccine.
