Human papillomavirus is a small, non-enveloped virus, so it needs our cells to copy its genetic material and be able to infect it.

Virions are the mature forms of the virus.

Vaccines to prevent infection by the Papillomavirus are made from the L1 region of the virus, making it safe for humans because it contains no active viruses.

Predisposing factors and frequent reinfection with the Papillomavirus are needed so that the cells of our organism can change.
