Allergic reaction

51 year old female, between 18-30hrs post first Pfizer jab, 5 Sept. Severe hives over her whole body- Dr told her it was a very rare side effect and gave her antihistamines. Hives were painfully itchy and she was also very lethargic and had significant brain fog. Hives cleared after 4 days. She was advised that she should get the second shot in hospital cos the reaction will be “at least twice as bad”. She plans on getting it. Her lethargy and brain fog continues three weeks later. I am closely related to this person and have firsthand knowledge.
