On an unknown date, Allergy test: The testing indicated no allergic reactions..         Patient was not taking any concomitant medications.  On 10-Dec-2021, the patient had undergone some comprehensive metabolic panel and CBC w/o differential tests.  Patient developed fever, muscle aches (expected) and rash (unexpected and unexplained) from the second dose vaccination of Moderna. After discussion with primary care provider, the patient was recommended to take booster dose of Pfizer vaccine and patient received it. This resulted in the patient having less fever and body aches but having several days of blurry vision and much more significant/severe longer-lasting rash along with itchiness for several weeks. The testing indicated no allergic reactions and the patient did not know whether it was safe to receive any additional COVID vaccinations or not and asked for advise.  Patient was treated with antihistaminic drug Claritin.
