A woman developed pruritic wheals on her face and bilateral, transient eyelid swelling 12 days after receiving a COVID-19 mRNA booster vaccine (Moderna). During examination, wheal and flare lesions developed on her upper eyelids and resolved after 30 minutes; light pressure applied to her skin with a tongue depressor elicited wheal and flare lesions within 3 to 5 minutes. What is the diagnosis and what would you do next?
