There are rumors in the market: the nine-valent HPV vaccine is useless if you are over 26 years old? The FDA's move is a slap in the face!

Since 2016, the mainland has been on the market. Every year, a human papillomavirus (HPV) vaccine for the prevention of cervical cancer is launched in the mainland of China. The dazzling rhythm makes people feel at a loss. Until this year, the State Food and Drug Administration (CFDA) approved the marketing of the nine-valent HPV vaccine, and the age limit for vaccination is 16-26 years old.

Ever since, most of the female friends over 26 years old have nothing to do with themselves, and there are even rumors in the market that it is useless for women over 26 years old to get the HPV vaccine, or it is only useful for virgins.

Just in the past few days, the FDA has slapped the face severely. Who said that the nine-valent HPV vaccine cannot be given if you are over 26 years old?

On October 6, the US FDA approved the supplementary application for the 9-valent HPV vaccine (recombinant human papillomavirus vaccine), expanding the applicable population to women and men aged 9-45.

This move by the FDA has undoubtedly confirmed that the nine-valent HPV vaccine is also effective for the 27-45 age group, with an infection prevention rate of 88%, and its safety is beyond doubt.

In fact, as early as 2014, the Hong Kong Food and Drug Administration licensed the two HPV vaccines on the market at that time to expand the scope of vaccination from 9-46 years old to premenopausal.

The Hong Kong Food and Drug Administration believes that after the start of sexual life, the possibility of infection with HPV virus is higher, and it is necessary to strengthen the prevention and protection of HPV virus. The age of 26 is not the upper limit of HPV vaccination, and the vaccine itself cannot effectively identify the age of the vaccinator to produce different effects. It should benefit a wide range of people who are at risk of HPV.

A survey by the Chinese University of Hong Kong found that there are two peak periods of HPV infection among women in Hong Kong, which are 26-30 years old and 46-55 years old. Professor Chen Jixiang from the Department of Microbiology of the Chinese University of Hong Kong explained that the peak of cervical cancer is 15 and 20 years after the peak of HPV infection, that is, 41-45 years old and 66-75 years old respectively.

To encourage middle-aged women to cope with the peak of female HPV infection, and then prevent cervical cancer 15-20 years later. Hong Kong recommends that women with conditions should be vaccinated.

The mechanism of the HPV vaccine is to attack the human immunity by imitating the HPV virus many times, so as to obtain the preventive immunity of the corresponding HPV virus, and then curb the throat of cancer!

It is useless to get the HPV vaccine at the age of 26. This is unfounded. Now the FDA has also expanded the vaccination age to 45 years old. The main purpose of HPV vaccination is to prevent HPV virus infection.

Age is not the main cutoff for HPV vaccination (+hkdoctors). Although most women who have sexual experience or have given birth have also had HPV infection, they will not be infected with the 9 HPV viruses covered by the vaccine at the same time. Therefore, women over the age of 26 who are married and have children still need to be vaccinated against HPV. In addition, the HPV virus is also closely related to diseases such as anal cancer, penile cancer, and genital warts in men. It is recommended that boys also be vaccinated as soon as possible.

How many years do vaccines last?

The HPV vaccine was launched in 2006, and the results in 2012 showed that there was no problem with the protective ability 5 years after vaccination.

Nordic studies have shown that there is no problem with the ability to protect 10 years after vaccination. Mathematicians have established a mathematical model that shows that there is no problem with the protection ability 50 years after vaccination.

Therefore, maintaining the protective ability for 10 years after vaccination is a conclusion, and 50 years is an inference. Whether it is correct or not needs time to test.

Since the first HPV vaccine was recommended in 2006, HPV infections among American teenage girls have decreased by 64%. In other countries, such as Australia, where HPV vaccination coverage is higher than in the United States, large declines have been observed in these HPV-related diseases.

Time flies so fast! Post-10s are about to enter the 9-year-old vaccination period. What are you waiting for? ~

Looking forward to the not-too-distant future, cancer will only exist in history like the "smallpox" virus in the past, and will no longer cause harm to humans!
