Some time ago, in an article on gynecological diseases sent by Dr. Clove, many girls came to ask about HPV vaccine:
How big is HPV vaccine better?
Is it useless to take HPV vaccine after having sex?
Can I still get HPV vaccine after I have been infected with HPV virus?
Dr. Clove will answer the question about HPV vaccine today.
1. How old is it better to play?
The younger the age, the better the immune response and the longer the benefit time after vaccination. Without sexual experience, the vaccination effect of adult women is still not as good as that of girls aged 11 and 12.
However, Japan’s three major authoritative institutions, the Japanese Society of Obstetrics and Gynecology, the Japanese Society of Pediatrics and the Japanese Society of Gynecology and Oncology, jointly issued a statement recommending that Japanese women can receive HPV vaccination until they are 45 years old.
By comparison, other authoritative organizations suggest the following:
ACOG, the American Association of Obstetricians and Gynecologists, recommends 9 to 26 years old, beyond which neither man nor woman needs to be vaccinated.
World Health Organization WHO recommends 9 ~ 12 years old.
FDA approved the use age of cervical cancer vaccine to be 9-26 years old.
Japan’s three major authoritative institutions recommend HPV vaccination before the age of 45, but the overall recommended age in advanced countries is 9-26.
2. Is it useless to fight again after having sex?
Vaccination with HPV vaccine is the best time before there is no sex life.
However, adult women who have had sexual experience still have HPV vaccination value, especially for women who have not yet been infected with HPV, they can still avoid HPV subtype infection.
3. Is it recommended to play after being infected with HPV?
For women infected with HPV, cervical cancer vaccine is still valuable and can reduce the risk of reinfection with HPV virus, but its effect is not as good as that of vaccination before infection.
HPV virus is a virus that women are extremely vulnerable to infection after sexual activity, and is also the main cause of cervical cancer.
The HPV infection rate is high, but the absolute incidence of cervical cancer is very low. The reason is that HPV virus can be eliminated by its own immune system in most cases.
Cervical cancer caused by HPV virus infection is a probability game. If HPV virus infection continues until precancerous changes, and finally malignant changes begin to develop and infiltrate, tragedy will begin.
At the same time, HPV also has a cunning characteristic. After the infection recovers, the human body cannot acquire enough immunity to resist reinfection. This is why it is repeatedly infected.
Here is the value of HPV vaccine-even if you have been infected before, after vaccination, you can be protected from re-infection with the subtype of HPV virus vaccinated during the effect maintenance period, from infection to recovery, and then to the cycle of infection.
Even, if you are vaccinated at the time of infection, then if the HPV subtype you are infected with is lucky enough to be naturally removed by your immune system in the future, you will not be infected with this HPV subtype again in the future.
However, this does not mean that HPV vaccination after infection has the same effect as before infection.
However, if the infection continues, the value of the vaccine in the infection subtype will tend to zero.
At the same time, for women whose HPV virus has been removed by themselves, but cervical lesions have developed, it is possible that even if you resist the reinfection of HPV through vaccines, you may have planted the seeds of future curse.
HPV vaccine is an important measure to prevent HPV infection and help prevent cervical cancer. However, even if the cervical cancer vaccine is completely missed, there is nothing worth worrying about. Regular cervical cancer screening can have a very good preventive effect.
At the same time, vaccination cannot be taken lightly. Vaccination is a common type of cervical cancer. Vaccination does not mean eliminating the possibility of HPV infection. Regular cervical examination must not be forgotten.
