* Known allergies, hypersensitivity, or intolerance to JNJ-64281802 or its excipients
* Any clinically relevant skin disease (as assessed by the investigator) in the past 3 months such as, but not limited to, dermatitis, eczema, drug rash, psoriasis, food allergy, and urticaria
* Reduced immune function to be: (a) Known or suspected congenital or acquired immunodeficiency; or (b) receipt of immunomodulation therapy within the last 6 months (such as anticancer chemotherapy or radiation therapy)
