The preventive effect of HPV vaccine on cervical cancer has always been self-evident; recently, the latest data released by the World Health Organization puts a big move to prove the importance of HPV vaccine.
The World Health Organization published a new study in the Lancet that HPV vaccine can eliminate cervical cancer.
Scientists analyzed data from more than 60 million people in 14 countries over the past eight years and found that HPV infection rates dropped significantly after the introduction of vaccines. Two cases of HPV 16 and 18, which caused 70% of cervical cancer, fell 83% among girls aged 13 to 19 and 66% among women aged 20 to 24. There is strong evidence that HPV vaccines can prevent cervical cancer and should be extended to boys and adults.
In a word, since the widespread use of HPV vaccines, the incidence of HPV infection and cervical cancer has dropped a lot, and the role of HPV vaccine is still a drop.
1. What should I do if I am infected with HPV?
First of all, don’t be afraid, take it easy.
Infection with HPV is very common. As long as there is a normal life, a little fairy with a sputum experience may be infected with HPV, which is as high as 80%-90%. Infected HPV is really sparse as usual.
Second, don’t be nervous.
Many little fairies will be very anxious to ask Xiaobian, who is infected with high-risk HPV subtypes, is it necessary to treat immediately. Xiaobian will recommend calming down first, don’t be nervous, HPV infection and cervical cancer are not exactly the same thing.
Regardless of whether the infection is high-risk HPV, 80% of HPV infection will be automatically removed within 1-2 years, HPV positive will automatically turn negative; only 5%-10% of HPV infection will continue and infiltrate, may continue to infiltrate It will take 20 years to develop cervical cancer.
Finally, do not take it lightly and diligently check.
Most of the time, HPV infection has no physical symptoms, 70%~90% is asymptomatic. If it is not a special examination, it will not be noticed. Many people will think that they are not hurting, nothing to ignore, not to go. Doing the appropriate checks, the results missed the opportunity of early discovery.
2. What is the role of HPV vaccine?
Regarding the promotion of HPV vaccines, everyone knows about the preventive effect of HPV vaccine on cervical cancer. The vast majority of cervical cancer is indeed caused by the HPV virus. In cervical cancer, the detection rate of HPV is as high as 99.7%.
HPV itself is a huge family, and the corresponding HPV vaccine is not only a preventive effect on cervical cancer.
At present, the most harmful to our body are the 14 high-risk HPVs of the HPV family, which are 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68. Type 73, correspondingly, HPV vaccines are also targeted at these high-risk HPV types.
1.Bivalent HPV vaccine
Mainly prevent HPV16, 18, can prevent 70% of cervical cancer. In China, because of the higher proportion of the two types of infection, the prevention of bivalent can be as high as 84%.
2. Four-valent HPV vaccine
Mainly prevent HPV6, 11, 16, 18, can prevent 84% of cervical cancer and nearly 90% of genital warts, as well as other cancers around the reproductive tract, such as genital warts, anal cancer, male penile cancer.
The concentration of protective antibodies produced by the tetravalent HPV vaccine against high-risk 16 and 18 HPVs also has clinical data and is also very effective in protecting cervical cancer.
3. Nine-priced HPV vaccine
Mainly prevent HPV6, 11, 16, 18, 31, 33, 45, 52, 58 type, a total of nine subtypes.
The preventive capacity of cervical cancer is directly increased from 84% to 92.1%, and at the same time it can prevent 90% of genital warts and other cancers around the reproductive tract.
3. Can men fight HPV vaccine?
At present, there is no injection of male HPV vaccine in China, but this does not mean that it is not necessary for men to play HPV vaccine.
Because of the nature and spread of the HPV virus itself, in addition to the little fairy, the other half of the HPV vaccine is still necessary.
Men who use HPV vaccine can protect themselves first, avoiding HPV infection and causing some related diseases. Secondly, their chances of carrying the virus are reduced, and they can better protect their sexual partners. Simply put, men who protect themselves by HPV vaccine protect themselves.
In fact, according to the World Health Organization, some countries have already included male HPV vaccination in the immunization program. According to the US Centers for Disease Control and Prevention (CDC), the 17-year-old male adolescents in the United States also achieved a 37% completion rate. .
4. Methods for preventing cervical cancer
Cervical cancer is the number one killer of the female reproductive system, and the incidence of cervical cancer has become younger and younger in the past 20 years. The incidence of cervical cancer under the age of 30 has increased by 6.4 times, and the incidence of 30-40 years has increased five times. many.
If there is no early treatment, the 5-year survival rate is no more than 60%, and the low immunity, the progress from HPV continuous infection to invasive cervical cancer will be greatly shortened to 5 to 10 years.
Fortunately, cervical cancer can be prevented. In addition to the HPV vaccine, as a relatively well-prepared cervical cancer prevention measure, the combination of HPV vaccine and cervical cancer screening can truly prevent cervical cancer.
According to the actual situation in China, the age of 25-30 years old began to be screened until the end of 64 years old, and the inspection methods used in each age group are different.
