cervical cancer screening is still needed after the HPV vaccine

The HPV vaccine has been a hot topic among female friends for two years, and the reservation of the HPV vaccine at the community health service center was sold out immediately after the delivery. Which HPV vaccine should be used in different age groups? Do you still need to be screened for cervical cancer after getting the HPV vaccine? Has had sexual life inoculated again significance big or not? Deng Minduan, chief physician of obstetrics and gynecology of Guangzhou Red Cross Hospital, answered the HPV topic that female readers are concerned about cervical cancer screening guidelines.

How to choose HPV vaccine at different ages?

The current HPV vaccines are bivalent, quadvalent, and nine-valent. Different vaccines are designed for different age groups according to their respective instructions, and should be administered strictly in accordance with the applicable age new cervical cancer screening guidelines. For example, bivalent vaccines are available for ages 9 to 45, quadrivalent vaccines for ages 20 to 45, and nine-valent vaccines for women ages 16 to 26.

Different vaccines have their own advantages, Deng explained. For the prevention of cervical cancer, both the bivalent vaccine and the quadvalent vaccine can reduce the risk of cervical cancer by 70%, and the nine-valent vaccine can reduce the risk of cervical cancer by 90%. The bivalent vaccine protects against HPV types 16 and 18, which account for 70 per cent of cervical cancer cases. In addition to preventing subtypes 16 and 18, tetravalent vaccines prevent additional subtypes 6 and 11. 6 and 11 subtypes of HPV virus and condyloma acuminatum this disease has a close relationship, the disease is recurrent in sensitive sites american cancer society pap guidelines, bring great pain to patients. HPV quadrivalent vaccine can reduce the risk of condyloma by more than 90%. The nine-valent HPV vaccine provides additional protection against five high-risk subtypes, which account for 20% of cervical cancer incidence. Therefore, the nine-valent vaccine can reduce the risk of cervical cancer by 90% and the risk of condyloma by more than 90%.

There are also some relatively high incidence of infection in China, namely subtypes “52” and “58”. These two subtypes occupy a relatively important position in China. If “52” and “58” can be prevented, the incidence of cervical cancer is expected to further decrease.If you get the HPV vaccine, you don’t have to do cervical cancer screening?

After any vaccine is vaccinated, its protection is not 100%. In other words, deng minduan explains: No matter which vaccine you get, you should still be screened for cervical cancer after you get vaccinated american cancer society cervical screening.The current recommended screening regimens for cervical cancer are TCT cytology and HPV, and if both tests are negative, a second test may be required after five years. If you only do THE HPV test and it comes back negative, the US guidelines also say you can do the test after five years, but the Chinese guidelines are a little bit more conservative, you can do the test after three to five years. Women can be screened for cervical cancer from age 25, and if they have been screened regularly and the results are negative, they may not be screened after age 65.

Many women find out they have HPV during screening and are so scared that they equate it with cervical cancer. In fact, don’t be afraid, if the screening results are HPV positive and TCT negative, a year after the review will be ok, most women through their own immunity can clear the virus. Data from the United States shows that women who have sex have at least a 90% chance of being infected with HPV in their lifetime american cancer society pap recommendations, but only a very small number of people actually get cervical cancer. The incidence of cervical cancer in China is more than one in 100,000. So, it’s not scary to get HPV, it’s scary to keep getting it, you can’t get rid of it. If your HPV test is positive, and you’re still positive a year later, be on your guard and continue to do further tests to see if there are any lesions.

Is it still useful to get HPV vaccine after you have sex with asccp pap smear 2019 algorithm pdf?

According to the World Health Organization, people between the ages of 9 and 14 who do not have sex are the primary targets for the HPV vaccine. But the reality is that 9 to 14 year olds are less likely to be vaccinated, and the most active vaccinated are actually adult women, who are more likely to be sexually active and even married. Deng minduan said it is also necessary for this group of people to get vaccinated. Because in China, unlike in other countries, the peak of HPV infection among women in other countries is in their teens, when they are young. However, there is a “double peak” phenomenon in the peak of the disease in China, that is, in addition to the peak in teenagers, there is a second peak in 40-44 years old.

So for Chinese women, even though they are older and have had sex, the vaccine can still provide some protection if they go to get vaccinated. But the older you get and the more you have sex, the more likely you are to get HPV. So in that sense, the older you get, the less effective you’re likely to get vaccinated, which is why we recommend early vaccination for young people, especially women who don’t have sex.

At the same time, HPV testing is not required or required before vaccination. Deng explained that vaccinators can be protected by the HPV vaccine even if they are already infected acog cervical cancer screening guidelines. For example, a vaccinator who had been infected with the more common HPV subtype 16 before the vaccination (the chance of being infected with both subtypes is extremely low) had improved her resistance to the 18 subtype even with the simplest bivalent vaccine.
