It was reported that on 21May2021 the patient received the second dose of vaccine and on an unspecified date in May2021 patient experienced symptoms of henoch-schonlein purpura (HSP), which consists of the inflammation of small blood vessels and one week after the dose of vaccine the symptoms of henoch-schonlein purpura flared up again and it can appear on the skin, intestines, joints and where small blood vessels started to leak. The reporter further stated that his son took the first dose of Covid-19 vaccine and developed Henoch-Schonlein Purpura (HSP) and stated as HSP is inflammation in the small blood vessels most commonly in children and it affects the skin, intestines and joints with leaking blood vessels. On his son's legs it looked like a vasculitis. His son had these red blotches under his skin. It didn't hurt. He also got vasculitis on his bowel. He had a colonoscopy to diagnosis the vasculitis on his bowel. His son was being treated with steroids. HSP was a chronic condition, and his son has been dealing with it from the last month. The doctor advised him to call Pfizer to report this information and to find out if there is data or any other complaints or notification for HSP from the Pfizer Covid 19 vaccine. He stated that patient does have other medical conditions as he had Crohn's disease and receives a Remicade infusion every 6 weeks, and he also takes Nutropin for growth hormones.

On an unspecified date, the patient underwent lab tests and procedures which included blood test which result showed no abnormalities and urine analysis which result did showed blood which also indicates HSP, and on 09Jun2021 colonoscopy which result was unspecified.
