Recently, nearly 300 students from the Chaohui Campus of Zhejiang University of Technology and Pingfeng Campus took exclusive chartered vehicles to the health service center for vaccination of nine-valent HPV vaccine. It is understood that this time, Zhejiang University of Technology contacted the nine-valent HPV vaccine manufacturer and successively provided HPV vaccine vaccination to 1,000 female students in school.
1,000 HPV vaccines, 7,000 people registered for
Why organize this HPV vaccination? Secretary Jia Kan of the Youth League Committee of Zhejiang University of Technology gave an explanation.
"Our core intention is to meet the needs of students. We have previously found that the student group has accumulated a large amount of demand for HPV vaccination, especially the nine-valent HPV vaccine that is difficult to make an appointment, and the call is even more urgent. Secondly, many well-known domestic universities have successively carried out similar activities, and the transmission volume is very large. We found that college students generally have such demands."
At the end of April, Zhejiang University of Technology launched 1,000 HPV vaccine appointment activities on WeChat, which attracted enthusiastic registration from students. After review, more than 7,000 students met the registration requirements. The school consulted teachers from relevant subjects, and after research and discussion, formulated a random lottery method, inviting teacher representatives and student representatives to conduct open lottery draws under the supervision of the Discipline Inspection Commission, and 1,000 vaccination quotas were drawn fairly and impartially.
In response to students’ questions and messages about vaccination, the school also specially invited Second Affiliated Hospital of Zhejiang University School of Medicine, Director Yan Chunxiao, to hold an online lecture for teachers and students before HPV vaccination, explaining to students the harm of HPV, the importance of HPV vaccination, the separation, vaccination procedures and precautions of HPV vaccine, etc. Through this form, the school has expanded the accessibility of vaccines as much as possible in accordance with the principle of fairness and justice, shortened the path to vaccination, and won unanimous praise from students.
The earlier women get the HPV vaccine, the better
Latest data shows that in 2020, the number of new cases of cervical cancer in China is about 110,000, accounting for 1/3 of the entire Asia. In the same year, among women aged 15-44 in China, the incidence of cervical cancer ranks third among female tumors, and has become the third leading cause of cancer death in women of this age in China. The incidence of cervical cancer in my country is increasing year by year, showing a trend of younger age, and the threat should not be underestimated.
On the other hand, cervical cancer is the only malignant tumor that can be prevented at present, and the only malignant tumor with a very clear cause. 99.7% of cervical cancers are caused by persistent infection of high-risk HPV.
HPV full name is human papillomavirus , which is a virus that is prone to infect the human epidermis and mucosa squamous epithelial . The infection route is contact transmission. There are currently about 200 types of HPV found. HPV is divided into high-risk and low-risk types according to different carcinogenicity. The high-risk types mainly cause cancer in the cervix, anus, genitals and other locations, and the low-risk types mainly cause genital warts and benign lesions.
Zhejiang University of Technology Hospital Director Pang Yuping introduced that HPV infection in in women in my country shows bimodal characteristics, one peak of infection is 17 to 24 years old, and the other is 40 to 44 years old. The previous age group was concentrated in college, so we first encouraged female college students to get vaccinated. President Pang emphasized: "At present, the incidence of cervical cancer in my country is developing towards younger age, so I suggest that the earlier women get the HPV vaccine, the better, especially before sexual intercourse, which can get the best benefits. Of course, women who have already had sexual intercourse have shown that HPV vaccine also has a good protective effect."
three different valence types. This is the
HPV vaccine as an effective means to prevent cervical cancer. There are currently three different valence types on the market, namely bivalent (9-45 years old), tetravalent (9-45 years old) and nine-valent (16-26 years old).
Director Yan Chunxiao, Second Affiliated Hospital of Zhejiang University School of Medicine, introduced that the differences between the three vaccines are, one is the difference between age groups, and the other is the difference between different types of viruses. Vaccines with high "price" cover more HPV types. The bivalent HPV vaccine includes two types 16 and 18, which can prevent 70% of cervical cancer. On the basis of types 16 and 18, the quadrivalent HPV vaccine also has types 6 and 11 that can cause genital warts.Therefore, in addition to preventing 70% of cervical cancer, quadrivalents can also prevent 90% of genital warts. The nine-valent HPV vaccine includes nine viruses, type 6/11/16/18/31/33/45/52/58. Among them, types 52 and 58 are among Chinese women. In addition to types 16 and 18, they are also relatively high-risk types of infection. Therefore, the nine-valent HPV vaccine can prevent about 92% of cervical cancer and 90% of genital warts.
It is reported that this year the nine-valent HPV vaccine is expected to be approved for women of a wider age group in China, and the supply of vaccines will also increase significantly. Previously, according to media reports, in the first quarter of this year, the domestic batch issuance of nine-valent HPV vaccines increased by nearly 280% year-on-year, and the current difficulty in making appointments is expected to be alleviated. Women can choose the appropriate vaccine for vaccination prevention as soon as possible based on their age and financial affordability.
In 2017, WHO clearly recommended that HPV vaccine be included in the national immunization program. As of October 2020, 110 countries and regions around the world have included HPV vaccines in the national immunization program.
prevents cervical cancer, there are tertiary prevention measures
cervical cancer has very clear tertiary prevention measures. primary prevention is a preventive vaccine for health education and HPV vaccination. secondary prevention is a regular screening. The purpose of HPV vaccine is to reduce the infection rate. The country recommends that women aged 25 to 64 can undergo regular cervical cancer screening. Third-level prevention is the treatment of cervical cancer, and appropriate treatments such as surgery, radiotherapy and chemotherapy are carried out according to clinical stages.
Director Yan particularly emphasized that smoking will affect local immunity and increase the incidence of cervical cancer. He advises everyone not to smoke, and not to start sexual behavior too early. It is best to have a protective sex life.
"We have about 20,000 women of appropriate age in our school, and more than 7,000 people have signed up, which means that about one-third of the students hope to obtain the opportunity to receive nine-valent HPV vaccination through our channel. This proportion is very high. We hope to continue to obtain support from community hospital , disease control and vaccine production companies, carry out similar activities regularly, and continue to carry out this project to benefit more female teachers and students of appropriate age in the future."
