Prior to vaccination, the patient was not diagnosed with COVID-19. Since the vaccination, the patient has not been tested for COVID- 19. It was reported that, caller calling on behalf of the patient. She was his wife of 63 years. He has a real problem. It was complicated. His birthday was (DOB) and he would be 90 years old this summer. He had hip surgery on 14Dec2020. The surgery was at (Hospital Name). He was diagnosed with CIDP which was chronic inflammatory demyelinating polyneuropathy. The treatment for CIDP was IVIg infusion. He had infusions for five consecutive days on 24Dec, 25Dec, 26Dec, 27Dec, and 28Dec (unspecified year). He wanted to get COVID vaccine. Pfizer does not have a lot of information for people who get IVIg infusions. On 19Jan2021 he got Pfizer's COVID vaccine and had no problems. On 01Feb2021 he had IVIg infusion because he has to wait 28 days between infusions. They had checked with the neurologist and they said a week then they changed it to 10 days. The neurologist said to go ahead because it was nine days. On 09Feb2021 he got second COVID vaccine. That was Tuesday. He was feeling great and walked into the place to get it. He was ok. He woke up yesterday and he was aching all over especially where he had the surgical hip revision on 10Feb2021 at 07:00. It was six inches above the knee to the top of the groin. It was a sharp pain. When he tries to lift his leg to walk it was especially sharp. He was trying to call the surgeon, but he was in surgery all day. The neurologist said to call Pfizer for any information about people who get IVIg infusion and have chronic inflammatory demyelinating polyneuropathy and the COVID vaccine. He walked into (Name) which was where he got it and he felt great. He walked out and came home. He has had no falls or nothing. He just came home. It was like a mystery. There was not a whole lot of information from Pfizer for people that get IVIg infusions except it started with seven days and now wait 10 days. She was trying to research it on the computer and it only says vaccines in general. It says there might be problem with vaccinations with infusions and she has read the literature that pertained to that. The article she read was from three years ago. It may just be a real unusual kind of thing that a person would have IVIg and get the COVID vaccine. She has been on hold for an hour. She has medical power of attorney for her husband. He had no problem with the first one at all. On the vaccine card she could not read the person's handwriting. Waited to do COVID vaccine on 19Jan2021 when he was in skilled nursing facility. He was in the hospital for 18 days and then went to the skilled nursing facility for 12 days. The only thing that was relevant was did the IVIg have an effect with the COVID vaccine because nothing else had changed. That was the only different thing. Morning after - body pain with continued sharp pain in left leg groin area - site of recent hip replacement on 10Feb2021 at 07:00. Morning of 13Feb2021- rash on right leg - calf region. The adverse events resulted in doctor or other healthcare professional office/clinic visit. No treatment was received for the adverse events. The action taken with immunoglobulins NOS for the adverse events was unknown. The outcome of the events was not recovered.  Follow-up attempts completed. No further information expected.
