What are the options for a cervical cancer vaccine? You don’t get cervical cancer if you’re vaccinated?
Cervical cancer, a malignant tumour that poses a serious threat to the health of women, continues to be a global problem. The advent of a cervical cancer vaccine has provided hope for the prevention of cervical cancer. However, many women are puzzled by the variety of cervical cancer vaccines available in the market and are not sure how to choose them, and have doubts about the effectiveness of their prevention.
At present, there are mainly two, four and nine price vaccines for cervical cancer. Two-valent vaccines are mainly for human papillomavirus (HPV) 16 and 18, the two subtypes being the main high-risk groups for cervical cancer, which cause about 70 per cent of cervical cancer. The two-valent vaccine, which is suitable for inoculation between the ages of 9 and 45, generally requires 3 doses, in the months of 0, 1 and 6 respectively. His advantage is that he is able to effectively prevent cervical cancer from the most critical high-risk virus type, and that it is relatively pro-people-friendly, suitable for women with limited financial means or a better age.
The fourth-price vaccine increased the prevention of HPV6 and 11, which are mainly related to low-level diseases such as sharp hysteria. The vaccination age range is 20-45 years, and the same procedure is used for 3 doses, 0, 2 and 1 in June. The four-valent vaccine, which not only prevents cervical cancer but also reduces the risk of acute hysteria, is a good option for women of appropriate age and concern.
Nine-valent vaccines cover types HPV6, 11, 16, 18, 31, 33, 45, 52 and 58, preventing approximately 90 per cent of cervical cancer and other related diseases. The vaccination age is 16 to 26 years, and the procedure for 0, 2 and 6 months is followed. The coverage of the ninth-price vaccine is broader, but due to the complexity of its production processes, the supply is relatively tight and expensive and suitable for young women with higher prevention needs and age.
However, vaccination against cervical cancer does not mean that cervical cancer will never be acquired. The HPV virus has multiple subtypes and the existing vaccine does not cover all the carcinogenic subtypes. And the protection of vaccines is not 100%, and there is a certain rate of immunization failure. Even with vaccination, there are still a small number of people who are at risk of contracting cervical cancer in the type of HPV not covered by the vaccine.
Thus, even with the vaccination of cervical cancer, women still have to undergo regular cervical cancer screening. Screening techniques include, inter alia, cervical cytology (TCT) and HPV testing. Women over 21 years of age who have sex should undergo regular TCT examinations and, if TCT results are abnormal, further HPV tests or vaginal lenses. Screening allows early detection of pre-cervical cancer or cervical cancer and timely intervention for treatment, thus significantly improving the cure and survival rate.
When choosing a cervical cancer vaccine, women must take into account their age, economic situation and prevention needs. At the same time, proper understanding of the role of vaccines cannot be seen as the only guarantee against cervical cancer. Maintaining a healthy lifestyle, such as avoiding early sexual activity, reducing the number of sexual partners and smoking, also helps to reduce the risk of cervical cancer.
Cervical cancer vaccine provides a powerful weapon for women to prevent cervical cancer, but only scientific choice of the vaccine, combined with regular screening and a healthy lifestyle, can create a strong line of defence in the fight against cervical cancer and maximize the protection of women ‘ s reproductive health. Let us be active, guided by science, away from the threat of cervical cancer.
