An 84-years-old male patient received bnt162b2 (PFIZER-BIONTECH COVID-19 mRNA vaccine, Solution for injection), dose 2 via an unspecified route of administration on 11Jan2021 (Batch/Lot number was not reported) as dose 2, single for covid-19 immunisation and also received remdesivir (REMDESIVIR), via an unspecified route of administration from an unspecified date (Batch/Lot number was not reported) to an unspecified date, for an unspecified indication.  Medical history included tested positive for COVID from 14Nov2020 to an unknown date and he had double pneumonia from an unknown date and unknown if ongoing. The concomitant medication was not reported. The patient had previously received the first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 mRNA vaccine, Solution for injection), dose 1 via an unspecified route of administration, on 28Dec2021 (Batch/Lot Number: unknown) for covid-19 immunization. The reporter stated the patient had tested positive for COVID on 14Nov2020. He progressively got worse and had to be hospitalized a few days before thanksgiving. He had double pneumonia. The reporter was not sure, but reporter thought it was not bad COVID pneumonia. A day or two after thanksgiving they administered Remdesivir with a COVID Cocktail. Reporter was not sure what else was in it. The patient was transferred into a nursing home for rehab for a month. As a protocol in the nursing home his first dose of Pfizer vaccine was 28Dec2020 and he got second dose on 11Jan2021. They said the patient should not get the vaccine if you got a monoclonal. Reporter was not sure if that is what the patient got. The patient was given the vaccine. Reporter enquired as is it a danger to the patient and they knew the patient tested negative three times before rehab. Reporter stated her father cannot even walk at this point. He was not your typical 84-year-old. He was driving and running up and down stairs. He lives in (State) and they would not accept him without two consecutive negative COVID test. Then they kept him in isolation for 10 days and tested him again and he was negative. When the patient was in the hospital he was on two different IV antibiotics. He kept getting worse. His oxygen levels were usually good and he never had to be intubated. They called her brother and told him they were going to start her dad on the COVID cocktail. That is how they described it. Reporter brother remembered that one of the medications was Remdesivir. Reporter was not sure if a steroid was in the cocktail. It had to be administered over a couple of days. Reporter has been on hold for close to two hours. Yesterday reporter was on hold for two and a half hours and she tried emailing but has not received an answer. Reporter clarified her question. Since it was less than 60 days is there any danger since the vaccine was administered. Reporter enquired does it affect the efficacy of the vaccine and was the patient going to have to have it again. Now the patient has 24-hour assistance at home. They were happy that he got the vaccine until they started to read that he should have waited 90 days. Reporter does not have exact information with reporter at the time of the call. It was two months and hard to get information without contact. Reporter does not have all the paperwork. He was on different things. Reporter declined to do a report at this time. There is a product complaint reported.  Description of Product Complaint: Caller is calling about her father.
