Can HPV Vaccine prevent Cervical Cancer? ( 甚麼是子宮頸癌疫苗? )

人類乳頭瘤病毒 (HPV) 感染是一種常見的性傳播疾病,但大多數 HPV 感染是無症狀的。感染了人類乳頭瘤病毒可能引致子宮頸癌、外陰癌、陰道癌、肛門癌和陰莖癌,亦會引致濕疣。接種子宮頸癌疫苗可以有效預防HPV感染,因而預防子宮頸癌和其他由HPV感染引致的疾病。

Human papillomavirus (HPV) infection is a common sexually transmitted disease, but most HPV infections are asymptomatic, so most people infected with HPV do not know that they are infected. Persistent HPV infection can lead to a variety of serious diseases. There are more than 170 types of HPV, but only certain types can lead to cervical cancer. Studies have shown that HPV types 16, 18, 31, 33, 45, 52 and 58 cause more than 90% of cervical cancers. In addition to cervical cancer, these viruses can also cause cancer of the vulva, vagina, anus and penis. Several other types such as types 6 and 11 can also cause skin warts and genital warts.

According to the Centers for Disease Control and Prevention, the HPV vaccine can effectively prevent a certain degree of HPV infection, and prevent cervical cancer, vulvar cancer, anal cancer, genital warts, etc.

The HPV vaccine should be given before infection. Since the HPV virus is primarily transmitted through sexual contact, the best time to get the shot is before any sexual contact. People who have had sexual experience or may have been infected with a certain type of HPV can also be effectively protected against other uninfected HPV viruses by receiving HPV vaccine. The HPV vaccine does not cause any HPV infection. For further information, please ask your family doctor.
