vaccine human papilomavirus


Yesterday I have begun to recive the vaccine in front of human papillomavirus (HPV). That consist in three dose administrated; now, two months later and the last one six months later.
I have recived this vaccine to prevent that infects the skin and mucous membranes of humans. Approximately 130 HPV types have been identified. Some HPV types can cause warts (verrucae) or cancer, while others have no symptoms. About 30-40 HPV types are typically transmitted through sexual contact and infect the anogenital region. Some sexually transmitted HPV types may cause genital warts, while others do not cause any noticeable signs of infection.
Persistent infection with "high-risk" HPV types — different from the ones that cause warts — may progress to precancerous lesions and invasive cancer. HPV infection is a cause of nearly all cases of cervical cancer.
Scientifics have demostrated relation between the virus and this pathology.
