Medical history included insomnia, anxiety, depression and culture anxiousness since she suffered from traumatic brain injury after car wreck and its severity, she is recovering, and on medication. She was unemployed and on disability due to her car wreck and she had a degree in marketing. She used to work for financial banking services prior to her traumatic brain injury. Concomitant medication included unspecified medication for traumatic brain injury after car wreck. Patient received her first dose of the Pfizer Covid-19 vaccine on 01Jun2021 and since then has had more pronounced insomnia, anxiety, depression and culture anxiousness (she had these since she had a traumatic brain injury). Her psychologist told her to receive the second dose of the vaccine but patient is wondering if it is okay to just get the one and not the second. Patient stated that she is kind of a weird case. She got her first dose on 01Jun2021 at a local health department and immediately started feeling weird, not during the day but at night. She couldn't sleep at all, but she does have insomnia but this was different. She has insomnia, anxiety and depression and so she was overanxious.  She had a lot of weird side of effects, not like throwing up but she did have diarrhea and nausea since 01Jun2021. Here's the bottom line, the whole week she felt mentally. Patient interrupted herself stating remember she had a brain injury, she felt this vaccine affected her brain and she didn't feel like herself. Patient is scared because of the way it made her feel. She stated that she has a lot of things stirring in her brain and causing her a lot of mental anguish, depression and anxiety and this vaccine made it even weirder. She stated everyone in family had had the vaccine with no problems. Patient stated that her side effects have gone away and part of it is because she is missing her mom and lost her dad in 2019, patient stated that she has not recovered from this and they were like peas in pod and the vaccine has amped up these things and how to relate to this. It irritated her when she cannot talk. She has a college degree.  She stated she wouldn't know how to relay this to the doctor. Her brain got overloaded and that was another problem. She takes medicine for this as well. Patient stated that she is beginning to feel stupid for calling, because she can understand people that have arm pain and stuff. Patient interrupted herself again and said she would just shut up. Outcome of the events was unknown.   Information on batch/lot number has been requested.
