Nose bleed; Blood pressure was 60/32; Headache; Sore arm; This is a spontaneous report from a contactable consumer (patient). A 71-year-old female patient received bnt162b2 (BNT162B2), dose 1 at vaccination age of 71-year-old via an unspecified route of administration on 15Jan2021 (Lot Number: EL8982) as dose 1, single for covid-19 immunisation. Medical history included ongoing hereditary haemorrhagic telangiectasia (she has a rare blood vessel disease called HHT - Hereditary Hemorrhagic Telangiectasia) and on ongoing nosebleed suppression. The patient family history included hereditary hemorrhagic telangiectasia which his father also has. Concomitant medication included tamoxifen (TAMOXIFEN) for nosebleed suppression from an unspecified start date and ongoing (reported as for having been on the medications for 4 years) and a thyroid pill (does not believe that is relevant to these events). The patient did not have prior vaccinations within 4 weeks. The patient reported that she was reporting severe epistaxis after receiving a dose of the Pfizer BioNTech Covid-19 Vaccine. She mentioned that she had to go to the hospital after the first dose due to severe epistaxis resulting in the loss of "a couple liters of blood". The patient mentioned that she gets periodically anyway as she has a history of Hereditary Hemorrhagic Telangiectasia (HHT). She added that HHT causes nosebleed because the blood vessels in the nose are deformed so they break and bleed. She stated that after each vaccine she had nosebleeds and since she gets them (nosebleed) all the time, she did not think anything of it. She inquired if her nosebleeds after the doses of the Pfizer BioNTech Covid-19 Vaccine could have been caused by the vaccine. She was told by an organization that there is specialist in that organization that monitor people with HHT diagnosis, and they told her the nosebleeds were just a coincidence. She also had sore arm and headache. She also stated that she had a sore arm for a couple of hours (15Jan2021) after each of the three doses of the vaccine. She stated that it was no big deal and was gone after those couple of hours and it's to be expected after a vaccine. As for her headache, she experienced it the day after her first dose of the vaccine (16Jan2021), she had a headache for about 2 hours (16Jan2021). She discussed that after the first dose of the vaccine on that Tuesday (19Jan2021), the patient got a nosebleed. She added that she lost about 2 units of blood and she had to go to the hospital by ambulance. She could not get it to stop bleeding. She stated that she looked up at one point and her blood pressure was 60/32. She further added that she was not admitted into the hospital. They stopped the bleeding and then sent her back home. She denied any labs, testing, or treatments relevant to events. She mentioned that she has an appointment with her hematologist tomorrow and they will check her hemoglobin. The event nosebleed required emergency room and physician's office visit. The outcome of the event nose bleed was recovered on Jan2021, for the pain in arm was recovered on 15Jan2021, as for the event headache was recovered on 16Jan2021, while the outcome of the other event was unknown.
