Human papillomavirus (HPV) is a human papillomavirus, and the HPV vaccine can be effective even if only two injections are given; two injections can also produce antibodies, but the value of the antibodies produced is not as high as that produced by three injections, so the prevention of cervical cancer does not have the desired effect. There are currently three types of HPV vaccines on the market, including the bivalent vaccine, quadrivalent vaccine and the nine-valent vaccine. The vaccine works to reduce the risk of cervical cancer caused by the HPV virus. There is no evidence that HPV vaccination is 100% safe from cervical cancer. It is recommended that all women of age should receive the HPV vaccine as early as possible and get all three doses as scheduled for better prevention of cervical cancer. It should be noted that HPV vaccine is not suitable for all women, such as severe allergies, pregnant women, breastfeeding, preparation for pregnancy, women with serious underlying diseases, should not receive the vaccine. If there is a need for vaccination, patients should be vaccinated under the guidance of a medical professional to avoid adverse consequences. After vaccination, cervical cancer screening should be conducted regularly for early detection and treatment of related diseases.
