What is the HPV vaccine?

Human papillomavirus (HPV) is a group of viruses with more than 150 different genotypes, some of which can infect male and female reproductive organs through sexual contact. Some high-risk genotypes of HPV can cause cancer, such as cervical cancer, vaginal cancer and anal cancer.

Cervical cancer is a common cancer associated with persistent HPV infection. Most cases of cervical cancers are caused by persistent HPV infection. Cervical cancer is a malignant tumor that affects the cervix. Cancer cells can penetrate from the surface of the cervix into deeper tissues and spread to adjacent organs. If not detected and treated early, it will spread to other organs of the body, such as the liver and lungs.

Scientific evidence has established that regular cervical cancer screening is an effective way to prevent cervical cancer. The HPV vaccine, on the other hand, reduces the risk of contracting HPV, thereby reducing the risk of cervical cancer caused by HPV infection.

Currently, there is a nine-valent HPV vaccine available in Hong Kong, which can prevent most cervical cancers. HPV vaccine is very safe. Some people who receive HPV vaccine may experience mild and short-term side effects. Common side effects include redness and pain at the injection site, fever, headache, and nausea. It should be noted that the HPV vaccine does not prevent infection of all genotypes of HPV, and it dose not clear the existing HPV infection.
