Therapeutic measures were not taken as a result of fibromyalgia. Therapeutic measures were taken as a result of dyspepsia.  Clinical information: Booster dose was taken due to high risk of frequent institutional or occupational exposure to coronavirus (and AT risk of serious COVID-19 complications) as her age was over 50. Vaccination Facility Type was Pharmacy or Drug store and not Facility. Fibromyalgia fare up after each Covid vaccine and booster, within 08 hours of shot. It started to resolve itself within one week after vaccine shot. It was recovering with sequelae. The second and third boosters caused heart burn and gastritis. At the time of report, she had to take medication for heart burn and gastritis every day. Medication controlled it but without medication, heart burn and gastritis came back. She was at higher risk for this due to long term use of anti-inflammatory drugs.  The information on the batch/lot number for BNT162b2 has been requested and will be submitted if and when received.
