Cervical cancer vaccine is a life-long immunity

At this stage of cervical cancer vaccine performance time is not long, only more than ten years, so at this stage this vaccine is not able to achieve lifelong immunity, there is no very accurate data. Some experts say at least 20 years, some experts say it can reach 50 years, so most women life injection is OK, but this vaccine injection is required to hit three shots, and the required time is within six months of injection. In addition, the vaccine can not achieve 100% immunity, so women still need to do regular cervical cancer screening, preferably once every two years, because the nine-valent cervical cancer vaccine can only achieve 90% prevention of cervical cancer.
