Pituitary does not work and take growth hormones/no growth hormones after his pituitary was injured 3 times; Forgets to take the injections daily/does have a difficult time remembering words; He does have problems with his brain function; Cough; Forgetting to take the medication is due psychological; Not have enough energy; Does not feel that great the day of or the day after receiving the COVID vaccine; This is a spontaneous report received from a contactable consumer or other non-health care professional (patient) reported for himself. A male patient of an unspecified age received second dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Formulation: Solution for injection, Batch/Lot Number: Unknown), via an unspecified route of administration on an unspecified date as dose 2, single for COVID-19 immunisation. Medical history included glaucoma, tremor (after the Heparin complications he was left with tremors) from an unknown date and unknown if ongoing. The patient concomitant medications were not reported. The patient previously took bnt162b2 for covid-19 immunisation and experienced no adverse event, heparin and experienced poisoned by heparin, left unconscious. Patient stated he was told early on patient may have took a 3rd dose of the Pfizer vaccine because my pituitary does not work and take growth hormones. He states nobody has told him if he needs to come back in 3 weeks or what so he did not know and wanted to call and check on this. He states he had no problem with the 2 doses and although he did not want to take it again, he would if he needs to. Caller took a regular dose of Omnitrope. At the first vaccination visit the caller did not get any helpful information or literature with the vaccine just the card and the follow up appointment. He stated that he has a hard time communicating with his health care professional due to her assistant not liking him. The literature the caller received at his 2nd dose he claims to be very helpful in indicating that he would be a candidate for the 3rd booster dose. Patient has been diagnosed with having no growth hormones after his pituitary was injured 3 times. He stated he actually forgets he was taking his medication although he has no trouble with his treatments he sometimes, or often times, forgets to take the injections daily. Caller states that he does had problems with his brain function but he feels as though it was improving. He did not not know how to explain it. He stated he has a cough but the cough was from a medication that was used due to his Glaucoma that irritated his cough. He does not think it has anything to do with covid and has had the cough since taking the medication. Patient stated he was not on a high dose of his Omnitrope and it stays in his system for 3 days. He claims him forgetting to take the medication is due psychological and due to possibly not wanting to take the medication. Caller also noted that he was poisone by Heparin he took about 2.5 years ago and was left unconscious by himself in the sticks alone. He stated his thinking ability has much improved since then. He does have a difficult time remembering words even though he knows what he wants to say. Caller claims to be doing much better. He states the meds have improved everything with me, I am a lot more clear, I remember names and everything better. Patient stated he did not have enough energy to deal with it in the beginning and it has improved my health in general. Caller reports after the Heparin complications he was left with tremors and when he has to talk about it he sometimes gets those tremors back in his right hand. Caller reports that he has started to write better. Caller stated he would get the booster dose in 28 days. Caller noted that he does not feel that great the day of or the day after receiving the COVID vaccine but he has been through so much more. I am getting better with the other things. No negative but I needed to check with someone who really knew, I was assuming. He questions maybe the wording they asked him before about his medications/condition or booster dosing was not clear. A third dose of the Pfizer-BioNTech COVID-19 Vaccine (0.3 mL) administered at least 28 days following the second dose of this vaccine was authorized for administration to individuals at least 12 years of age who have undergone solid organ transplantation, or who are diagnosed with conditions that are considered to have an equivalent level of immunocompromise. Caller stated that he was unable to get his 2nd dose of the vaccine as scheduled and had to wait 4 weeks nearly 5 weeks to get it. He was not sure if this made a difference or not. He stated that the vaccination site was set up at his local grocery but they were gone for the 2nd dosing round and he had to travel further to get the vaccine. Caller would like to know how he goes about getting the 3rd vaccine. He questions what he should bring when he goes to get the vaccine and if he should bring his medication to prove anything. Treatment was received for the events. The outcome of the events was reported as blood growth hormone decreased, mental disorder, feeling abnormal was unknown and memory impairment, cerebral disorder, asthenia was recovering was cough not recovered.   The lot number for the vaccine, [BNT162B2], was not provided and will be requested during follow up.
