A while ago, many girls came to ask about the HPV vaccine:
- What age is vaccinal HPV vaccine better?
- After having sex, vaccinate HPV vaccine again is useless?
- After having been infected with HPV virus, can you still be vaccinated with HPV vaccine?
Let’s answer those three questions today.
What age is suitable for HPV vaccination?
The younger the age is, the better the immune response is and the longer the benefit time is. In the absence of sexual experience, adult females continue to be less effective than girls aged 11 and 12.
But Japan’s three leading institutions, the Japanese Society of Obstetrics and Gynecology, the Japanese Academy of Pediatrics and the Japanese Society of Gynecological Oncology, have issued a joint statement recommending that Japanese women be eligible for HPV vaccination up to the age of 45.
By way of comparison, other authorities recommend the following:
- The American College of Obstetricians and Gynaecologists (ACOG) recommends 9 to 26 years of age, beyond which both men and women do not need to be vaccinated.
- The World Health Organization (WHO) recommends 9 to 12 years of age.
- The age of use of cervical cancer vaccine approved by FDA in the United States is 9 to 26 years old.
Japan’s three leading authorities recommend HPV vaccination before the age of 45, but the overall recommended age in advanced countries is 9 to 26 years old.
After having sex, vaccinate HPV vaccine again is useless?
Getting the HPV vaccine is the best time to be without sex.
However, adult women who have had sexual experience still have the value of HPV vaccination, especially for women who have not yet been infected with HPV, and can still avoid the HPV subtype infection they have received.
After having been infected with HPV, can you still be vaccinated with HPV vaccine?
In women who had been infected with HPV, the cervical cancer vaccine was still valuable in reducing the risk of reinfection with HPV, but was less effective than in women who had not been vaccinated.
HPV is a sexually active virus that is extremely susceptible to infection in women and is the main cause of cervical cancer.
The infection rate of HPV virus is high, but the absolute rate of cervical cancer is very low. The reason is that, in most cases, the HPV virus can be eliminated by its own immune system.
HPV infection and cervical cancer is a game of chance, if the HPV virus infection continues until the precancerous change, and eventually malignant and began to develop, infiltration, the tragedy began.
HPV also has a cunning feature that the body does not have enough immunity to resist reinfection after the infection recovers. That’s why they’re repeatedly infected.
Here is the value of the HPV vaccine-even if you have been infected, after vaccination, in the effect of maintenance period, you can protect against re-infection with the subtype of HPV virus, from infection to recovery, to the cycle of infection.
Even if you are vaccinated at the time of infection, you will not be infected with this HPV subtype in the future if your immune system is lucky enough to wipe out the HPV subtype that you are infected with later.
However, this does not mean that post-infection HPV vaccination has the same effect as pre-infection.
However, if the infection continues, the value of the vaccine in the infected subtype tends to be zero.
For the HPV virus has been self-eliminated, but the cervical lesions have been pathological changes in women, you may be able to resist the re-infection of HPV through the vaccine, may have planted the seeds of the future.
HPV vaccine is an important measure to prevent HPV infection and help prevent cervical cancer. But even if completely missed the cervical cancer vaccine, there is no cause for panic, regular cervical cancer screening can have a very good preventive effect.
At the same time, the vaccine can not be taken lightly, vaccination is a common type of cervical cancer, vaccination does not mean to eliminate the possibility of HPV infection, regular cervical screening must not be forgotten.
