HPV vaccines help to prevent infection by certain strains (e.g. types 16 and 18) of the Human Papillomavirus (HPV), which may lead to cervical cancer in women. Some HPV vaccines can also help prevent vaginal and vulvar cancer in women, anal cancer or genital warts in both women and men
HPV infection spreads from one person to another through skin-to-skin contact like sexual activity, or infrequently during delivery from an infected mother to her baby.
Most HPV infections, including with strains that can cause cervical cancer, do not have any signs or symptoms. Symptoms of cervical cancer may include abnormal vaginal bleeding such as bleeding after menstrual periods or after sex. There may also be changes in the amount, colour or smell of the vaginal discharge. It is recommended to have regular screening, e.g. Pap smear to detect cervical cancer early.
