Can high risk hpv viruses be 100% cleared by the immune system if they enter the body?

You ask the same question with minor adjustments. The family of HPV viruses are well known for an ability to be cleared initially by a normal bodies immune system after about 2 years, however, they can become dormant in select tissues and re-activate months/years/decades later. Vaccination that prevents infection or avoiding infection is the only way to never have dormant HPV.
