This consumer (patient's wife) reported for an 84-year-old male patient (reporter's husband) who received 1st dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE; lot EW0158) on 10Apr2021 at right arm for COVID-19 immunization. Relevant medical history included ongoing high cholesterol diagnosed a long time ago when he was very heavy at one point he was quite heavier than he was. Now he was skin and bones, ongoing high blood pressure diagnosed 10 years ago or longer and ongoing diabetes diagnosed 10 years ago, ongoing pacemaker and ongoing irregular heart beat and falls. The patient previously had sore arms at site after receiving the flu shot for immunization. Ongoing concomitant drugs included Carvedilol for high blood pressure, atorvastatin calcium for high cholesterol, amiodarone (this is the medication that would cause an issue with the antibiotic if it was taken orally), acetylsalicylic acid (BABY ASPIRIN) to thin his blood, sitagliptin phosphate (JANUVIA) for diabetes, vitamin D3, cyanocobalamin (B12), ubidecarenone (CO Q10), sertraline (generic of an old drug called Zoloft) as something to calm him down. The patient was scheduled to get the second vaccine on 01May2021, however he was in the hospital and did not have his. They rescheduled the vaccine for this coming Saturday because he was still in the hospital. He was actually getting moved to a rehabilitation facility with intravenous antibiotics for a urinary tract infection and will not be able to get it. The patient was on an IV antibiotic which could not be administered orally do to the fact he has a pacemaker and irregular heart beat. The doctor told her that the oral medication would interrupt the spikes of the pace maker, his heart.  The reporter was wondering if her husband can still have the COVID vaccine while taking the antibiotic. She asks will it interfere with that medication. Will he have to start all over again with number one of the vaccine because he missed the vaccine in the allotted time span. The last time the patient was weighed he was 155, but he has not been eating since he has been ill. He had so many problems since he has been ill, he has been falling a couple times.  The reporter wanted to protect him from the terrible disease, but didn't want the injection into his body creating anymore problems than he already has. The doctor said that she thought the caller could take the patient out of the rehab facility for the day and get his vaccine and then bring him back. The facility said they would have to do research about that and get back to her. Caller states that her husband kept falling and had a fracture at the base of his spine, in addition to other problems, he has gout in one knee. She states that he would be standing up talking to her and the next thing she knew he was on the floor. She states that he has fell six times in a month. She states that she has become friends with the fire department because they came out so much. The falling occurred before he got the vaccine. She states he was fine when he went for the first vaccine and then the following week it started all over again, he couldn't walk. He had a physical therapist helping him strengthen his walking. She states that her husband says he fell and hurt his right knee while working with the physical therapist and the physical therapist said no, no, no, he didn't fall, he had a strap wrapped around him and the physical therapist caught him before he fell. Caller states that the physical therapist is 30 pounds lighter than her husband and doesn't know if he could of grabbed him before he hit the floor. She states that her husband was in a lot of pain and his knee swelled up, was very hot. She states that the doctor said it was inflamed. She states that she brought him back to hospital because they could not get him up and he could not walk. She couldn't pick him up, her son couldn't pick him up, her daughter couldn't pick him up and her son and daughter together finally got him up but he couldn't walk. She states that she called the emergency medical team. They said he has to go to the hospital and that was the last time he was at home. Has a walker and it takes a little while. She didn't know if he got the gout from that knee, but when they took out his fluid the following day you could of heard him screaming in the next county over. They were suppose to have the results but they didn't, they discharged him from the hospital. She states that he hasn't been able to come up with a breather of fresh air and feeling better.  Caller states that he was now taking a gout medication at the hospital and that they told her that her husband had a second fracture to lower spine. The outcome of the events was unknown.
