Write-up: This is a spontaneous report from a contactable consumer (patient) received from the Regulatory Agency. A 37-year-old female non-pregnant patient received bnt162b2, via unspecified route of administration on 22May2021 (batch/lot number and expiry date unknown) as 1st dose, single for covid-19 immunization. Medical history included menstruation irregular, lactation decreased, poor sucking reflex, suspected covid-19 from 20Apr2020 to 01May2020. The patient since having a coil fitted in 2018, the patient sometimes had irregular bleeding. The patient had a few tests, scans etc., but nothing was conclusive, otherwise, there would be no other reason for her to be bleeding at a mid-point between periods. The patient not had a COVID-19 test, not enrolled in clinical trial, not currently breastfeeding. The patient''s concomitant medications were not reported. On 01Jun2021, the patient experienced bleeding (medically significant) and bleeding vaginal. The patient informed that her period started the day before having the vaccine (21May2021), so to be bleeding at 11 days after the start of her regular period showed (01Jun2021) that it was irregular bleeding. The bleeding was fairly heavy, although not painful. The patient logging the symptoms on the day they had appeared, so the patient was not sure yet when or how they will be resolved. The patient has not tested positive for COVID-19 since having the vaccine. The outcome of the events was not recovered. No follow-up attempts are possible, information about batch number cannot be obtained.
