Should adults get the HPV (Human Papillomavirus) Vaccine?

With the recent approval of the HPV vaccine in my country to expand the vaccination age to 9-45 years old, the most frequently asked question is: is the vaccine vaccinated as soon as possible? Do adults need to be vaccinated? HPV is sexually transmitted, and most infections clear up on their own, but a few cause genital warts, cervical or anal cancer. The HPV vaccine can effectively prevent infection and thus prevent the occurrence of these cancers. A research article published by Lancet in 2021 pointed out that when the first-generation (bivalent) HPV vaccine is vaccinated in adolescents, especially at the age of 12-13, the incidence of cervical cancer will be greatly reduced or even zero.

Basics of human papillomavirus

The virus has 150 subtypes, 40 of which can be cause cancer. The existing nine-valent vaccine can prevent nine subtypes of infection and cancer, with an effective rate of 90%.

At what age should the HPV vaccine be given?

The recommended age for vaccination by the US Centers for Disease Control and Prevention is 9-26 years old. The earlier the vaccination, the better the effect, because the immune response is better before the age of 12, and only two doses can achieve satisfactory results. Three doses are recommended over the age of 15. Should adults over 26 still be vaccinated? Yes, but the CDC does not recommend vaccination for people over 26 years old, and the American Cancer Society does not support the vaccination of people aged 26-45. The reason is: most people may have been infected with HPV after having sex, and there is no point in getting vaccinated. Of course you may not be infected with all carcinogenic subtypes, and vaccination may also make some sense. People over the age of 26 who are not sexually active should be actively vaccinated.

How can cancer caused by HPV be prevented?

Of course the HPV vaccine is the best way. Follow the doctor's advice to do cervical smear and HPV tests on time. Early detection of cervical cancer and other related cancers can lead to early treatment, and the cure rate of early cervical cancer is very high. It is especially important for pediatricians to actively recommend that children over the age of 9 receive the HPV vaccine, the earlier the better.
