What is cervical vaccine?

Quadrivalent HPV vaccine is generally referred to as quadrivalent HPV vaccine. It can prevent HPV types 6, 11, 16 and 18 infection and is suitable for women aged 9-45. Quadrivalent HPV

vaccine has clear effectiveness in preventing cervical precancerous lesions and cervical cancer caused by HPV types 16 and 18. These two types of HPV are the main high-risk types that cause cervical cancer. Vaccination can stimulate the body to produce specific antibodies, thus neutralizing the virus and preventing the virus from infecting cells when HPV infection occurs. In addition to cervical cancer, quadrivalent HPV vaccine also has certain preventive effects on genital warts caused by HPV types 6 and 11. These diseases, although not malignant, can cause physical and psychological discomfort to patients.

They usually require three shots at intervals to achieve optimal immunity, but the specific timing and interval of vaccination should follow the doctor's recommendations.
