Upon receipt of follow-up information on 28Jul2021, this case now contains all required information to be considered valid.  This is a spontaneous report from a contactable consumer (patient). This 27-year-old male patient received the second dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE), intramuscular, administered in arm left on 22May2021 09:15 (at the age of 27 years) (Batch/Lot Number: EW0173) as a single dose for COVID-19 immunization. Concomitant medication included unspecified multivitamins. No additional vaccines were administered on the same date of the Pfizer suspect. Patient did not receive any other vaccines within 4 weeks prior to the COVID vaccine. Patient previously received the first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE), intramuscular, administered in arm left on 01May2021 09:15 (Batch/Lot Number: EW0172). Historical vaccine information also included tetanus shot a year ago because he had cut a tendon in his hand. Hand got better, it was really intense. He thought he was going to lose his thumb, but he was quick with the medical tape. He had a miraculous recovery in 5 months. No AEs following prior vaccinations. He's never had any medical reactions or allergic reactions or anything before. Patient did have any side effects on 23May2021. On 24May2021 at 22:00, 48 hours after vaccination, patient had a massive out break of bleeding ulcers that lasted for 18 days. At first, patient was spitting out mouth and had falls of blood. Patient never had anything like this before. The doctor said that the patient would be fine and he healed. Patient had a bunch of sores in the mouth and they were "attached where the gum meets the tooth". He reported that these sore did not sting or burn but they bled a lot, and that they could be from stress. He had no sexual contact with anyone or shared drinks for a longtime with anyone. He did not know what it is, but it doesn't look like canker sores or herpes. He is not sure if this was a side effect. He took photos and sent them to a medical professional who said not to worry about it and that it would go away. The patient thinks it came from the vaccine. It is the only thing he has done differently. He has not had any tests. He talked to a person who said it didn't look like it needed to be tested and don't worry about it. Patient underwent tests which included STD Test in "Apr" with result negative (had to get tested for future wife), HIV test in "Jun" with result negative (had to get tested for future wife). Event bleeding ulcers was reported as serious with seriousness criteria: important medical event, required call to physician, but did not require the initiation of new medication/other treatment/procedure. The outcome of the event stress was unknown and of the other events was recovered on an unspecified date in Jun2021.  Follow-up attempts are completed. No further information is expected.
