he was taken by ambulance on February 10th to the local hospital ER/ said that it was COVID; This is a spontaneous report received from a contactable consumer (patient's son). A 71-year old male patient received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, lot number EN5318), parenteral in the arm on 29Jan2021 (at the age of 70-year-old) at single dose for COVID-19 immunization. The patient's medical history included type 2 diabetes, heart attack on unspecified date in 2000 and shingles turned into neuropathy. The patient's concomitant medications included clopidogrel bisulfate (PLAVIX). Reporter was calling on concern of her/his father (patient) actually who still on ventilator (vent) due to your Pfizer's vaccine. So, he/she was told by the FDA to call directly Pfizer since it was a Pfizer vaccine that was given the first dose. He/she had already it reported it to their but he/she was not sure what all you need but he/she still pretty confident that it had a lot to do with vaccine that was given to him the first dose. At the time of this report he was on vent, he had been on for 40 days. He had the shot on 29Jan2021, his very first dose and then his very first symptom was on 05Feb2021. He also got a heart attack. I believe it was a triple bypass done back in 2000 but he did not have any heart damage. But he was on PLAVIX and he/she did not know all of his medication he was on. He/she had tried to look that up but he/she did not want to tell any other just in case he/she said that wrong, he/she honestly could not say what he was and wasn't taking at the time. He was taking the product, but he/she did not know the dose. He/she know for sure that he was on PLAVIX but did not know the dose. The other medication, no he/she would not have the names and dosage because he/she did not want to tell you because it was not, he/she did not truly know. About the start date of PLAVIX reporter stated he would have been started that probably in 2000 after his heart attack as far as he/she know but he/she could not confirm that. That was his/her rough guess as far as he/she know. As per dose reporter stated he she did not. About route of administration reporter stated, he/she could not give any information, on his dosages, his medications or anything because he/she did not want to give any false information. So, he/she did not have any of that exact information. He/she just know he was and he was on PLAVIX, that was the only one he/she know for sure, he/she did not know any dosage, he/she did know he was on other medication but he/she did not know any name or dosage so he/she did not want to give any false information. He also had shingles and also it had turned into neuropathy that was another thing he was dealing with at the time of the vaccine. As per lab data reporter stated his first symptom was around 05Feb2021 he was taken by ambulance on 10Feb2021 to the local hospital emergency room (ER), he was diagnosed with the flu and then later they called him in evening and said that it was COVID and by then he was staying home. The 11Feb2021 to the 13Feb2021, progressively getting worst, began to get a high fever, was unable to walk, uncontrolled bowel, etc. more of a flu (reported as flue) issue. And he was rest again by ambulance on 13Feb2021, he was taken to a bigger hospital. He was admitted to the intensive care unit (ICU) on 13Feb2021, he had a multiple lab done daily since then. He was on vent since then. He was put on the vent on 15Feb2021. When confirmed if it was after vaccine administration, reporter stated, after the vaccine, he got his first symptom 7 days after the vaccine. His vaccine was on 29Jan2021, his very first symptom which was very mild was on 05Feb2021. He progressively got worst and was admitted to the ICU on 13Feb2021 and then was intubation endotracheal (ET) tube on 15Feb2021. As per outcome of the event reporter stated he was still on the vent, he was, reporter would say improving since they told that probably never went to, he was actually going to die, they were pretty much planning a funeral. But he was now on a tracheostomy and he was walking up. So, they could say he was improving but he was still on a vent. As per hospitalization date reporter stated his very first day he went to the hospital would have been 10Feb2021 and that was when he was diagnosed with the flu and then later that evening after he was already home they called and said that his test came back positive for COVID also. But then he went back to the hospital by the ambulance again when he started not being able to walk or anything on 13Feb2021. When confirmed if he was still in hospital, reporter stated, his/her father was still on vent. Fighting for his life. He was in a long-term acute care center at the time of this report, he was moved from ICU to a long-term acute care as of the day before the present report (23Mar2021). He had been on a ventilator breathing for him for 36 days. The outcome of the event was resolving.
