Abstract:

Objective: To date, the vaccine is the only weapon to stop the global pandemic caused by the SARS-CoV-2. But, several clinical cases of complications have been reported in the literature especially allergic reactions.

Case Report: We report a case of 35-year-old woman, known asthmatic with history of chronic urticaria, allergic rhinoconjunctivitis and angioedema after taking NSAIDs. The patient was presented 10 minutes after administrating Pfizer-BioNTech vaccine, an immediate allergic reaction complicated 12 hours followed by angioedema.

Discussion: During the first wave of COVID-19, and after the initiation of the vaccination program in Morocco, vaccinating people with severe allergies was not recommended. This reality was changed after the second wave of SARS-CoV-2 Delta, on condition of doing it under medical monitoring. We should propose to all risky persons to take premedication if needed to avoid such reactions considering the benefits incurred. The use of anti-histamines seems to be necessary. But as in our patient’s case, anti-histamines alone were not sufficient to avoid this local reaction. They probably reduced the intensity of the reaction but did not avoid it. Therefore, we proposed a combination of drugs made by corticosteroids and anti-histamines as a premedication may be a safe alternative for the patients with risks and last but not least a, close monitoring was proposed.

Conclusion: The main purpose of this case is to raise awareness of this side effect among practitioners and make them capable to manage it correctly.
