Inclusion Criteria
  • Healthy on the basis of physical examination, medical history (at screening only), and vital signs performed at screening and Day -1. If there are abnormalities, the participant may be included only if the investigator judges the abnormalities to be not clinically significant or to be appropriate and reasonable for the population under study

  • All women must have a negative highly sensitive serum (beta human chorionic gonadotropin [beta hCG]) at screening and a negative urine pregnancy test at Day -1
  • Contraceptive use should be consistent with local regulations regarding the use of contraceptive methods for participant participating in clinical studies
  • Must sign an informed consent form (ICF) indicating that the participant understands the purpose of, and procedures required for, the study and is willing to participate in the study, before starting any screening activities
Exclusion Criteria
  • Any history of clinically significant skin disease such as, but not limited to, dermatitis, eczema, drug rash, psoriasis, food allergy, and urticaria
  • Known allergies, hypersensitivity, or intolerance to JNJ-64281802 or its excipients
  • Has been dosed with JNJ-64281802 in past 3 months
  • Current human immunodeficiency virus type 1 (HIV-1) or type 2 (HIV-2) infection (confirmed by antibodies) at screening
  • Current Coronavirus disease 2019 (COVID-19) infection (confirmed by severe acute respiratory syndrome coronavirus 2 [SARS-CoV2] polymerase chain reaction [PCR]) at the time of admission to the study site (Day -1)
