On 24Aug2021, the patient received a booster dose and went home first. No one lives with her and she lives alone. The reporter's brother went to see her, and she was almost at her death. He called 911 and they took her to the hospital, and she died on 25Aug2021. An autopsy was not performed. The reporter wanted to know why did this happen to her and what caused her death and what happened to her. She was just trying to help the public after this happened. Doctors should be informed and the public needs to be informed on when to take the shot and when not to take the shot. She doesn't have all that information on when the patient received the first and second dose and just know that patient took it at the doctor's office, she went home, and she died after getting the vaccine. The caller asked if adverse reaction/experience may be related to the product or not and response was provided that Pfizer cannot assess causality and doctor/healthcare provider is in the best position to assess and advise as your doctor/healthcare provider was most familiar with your medical condition, clinical history, how your treatment has been conducted and any relevant information to your specific case. And also informed that Pfizer was unable to make recommendations or diagnoses on a case-by-case basis for individual patients. It was the healthcare professional's discretion with their use of clinical judgment to determine the safety of their patients. The caller was offered to provide CICP information and offered to provide Pfizer legal teams address and fax number. The reported that it was her sister in law so she doesn't have all the information, she doesn't have the doctors name or what was going on with her. She doesn't know a lot of information to give at this time. She said there was type of website to get some compensation. Do they reimbursement right after or when? She talked to someone in VAERS. She really doesn't know what to report, or why or what happened. She doesn't know if it was a blood clot or what. The doctor just gave her the shot. Maybe the patient needed the booster because her immune system was not up to par. She would like to know more information from the doctor. The caller asked who is capable of getting the booster shot? Is it just people that are immunocompromised or is it specific ages like people above 65 years old? The caller asked if people taking certain medications that don't allow the vaccine to work properly would be included in this group or not. The caller stated the way they have it on TV and everywhere she was thinking that everyone is able to get a booster. She stated the understanding is that certain ages over 65 can get it. (documenting as potential Pfizer complaint because she was commenting on how the guidance is not clear). The caller asked how long it will take to get the email from, agent (she just spoke with her prior to getting transferred. She stated everything is important in regard to timing, this needs to be handled quickly. She was not sure if Pfizer would want an autopsy, but they cannot afford it. She had spoken with (withheld) about wanting compensation and (withheld) was going to send an email because she asked for this in writing and not verbally. She stated she could take this information verbally now. The caller stated she has another family member that takes medication that is on the list of meds that keeps the covid vaccine from working and wanted to know if they could get a booster dose.  The lot number for the vaccine, [BNT162B2], was not provided and will be requested during follow up.; Reported Cause(s) of Death: unknown
