Company comment This is a spontaneous case concerning a 27-year-old male patient with medical history of Hay fever, Pollen allergy, Seasonal allergy, Mycotic allergy, Asthma, Hypersensitivity, Food allergy and Dust allergy, who experienced the serious, unexpected event of angioedema and other non-serious events such as pruritus, erythema, sensitive skin, sensation of foreign body, dyspepsia, hyperhidrosis, oropharyngeal discomfort, chest discomfort, bronchospasm, wheezing, urticaria, cough, paraesthesia, feeling hot, flushing, gastrooesophageal reflux disease, feeding disorder, insomnia, mechanical urticaria, asthma, hypopnoea, feeling cold, suspected blood glucose decreased, dry mouth, thirst, diarrhoea, hypoaesthesia, rash, chills and nausea.  The events started developing approximately 10 days after the third dose of mRNA-1273 vaccine. As reported, there were no such events after the first two doses of mRNA-1273 vaccine. The rechallenge is not applicable since the events occurred after the third dose. The medical history of multiple allergies, Asthma, Hypersensitivity remains a confounder. The benefit-risk relationship of mRNA-1273 vaccine is not affected by this report.   Most recent FOLLOW-UP information incorporated above includes: On 01-Jan-2022: Follow-up received contains significant information. The case has been upgraded to serious. Updated patient demographics, medical history, and concurrent conditions Added the lab investigations and updated the route of administration for all the doses of suspect drug. Updated concomitant and treatment medications. Added new events and event outcome was updated.; Sender's Comments: This is a spontaneous case concerning a 27-year-old male patient with medical history of Hay fever, Pollen allergy, Seasonal allergy, Mycotic allergy, Asthma, Hypersensitivity, Food allergy and Dust allergy, who experienced the serious, unexpected event of angioedema and other non-serious events such as pruritus, erythema, sensitive skin, sensation of foreign body, dyspepsia, hyperhidrosis, oropharyngeal discomfort, chest discomfort, bronchospasm, wheezing, urticaria, cough, paraesthesia, feeling hot, flushing, gastrooesophageal reflux disease, feeding disorder, insomnia, mechanical urticaria, asthma, hypopnoea, feeling cold, suspected blood glucose decreased, dry mouth, thirst, diarrhoea, hypoaesthesia, rash, chills and nausea.
