Possibly have you previously endured a runny nose? Perchance did you do away with the cold? Certainly you did! You can not cure a cold directly, but your immune system usually establishes resistance to any cold infection within a few days. That is called cured by your very own immune system!

HPV virus is identical in that human papilloma virus is simply an additional viral infection. Therefore you can normally create immunity to human papilloma virus.
