Embodiments relate to methods comprising expressing or overexpressing P-selectin glycoprotein ligand-1 (PSGL-1) in human immunodeficiency virus (HIV) producing cells; isolating HIV particles from the HIV producing cells; and preparing the isolated HIV particles as a HIV vaccine. Embodiments relate to systems comprising a HIV vaccine comprising live attenuated, inactivated, or non-infectious HIV particles. Embodiments relate to systems capable of performing a method comprising administering a vaccine comprising live attenuated, inactivated, or non-infectious HIV particles to a subject in need of the vaccine; and treating or preventing one or more disease states in the subject resulting from HIV infection. Embodiments relate to methods comprising expressing or overexpressing PSGL-1 in virus producing cells; and inhibiting viral infection; or inhibiting viral spreading; or inactivating viruses and virus producing cells; or producing non-infectious virion particles; or allowing the virus producing cells to produce non-infectious virions, isolating the virions, and preparing non-infectious virions, the virions being HIV particles.
