HPV vaccine after 45 years old

After the age of 45, it is recommended that you do not need to get the HPV vaccine. HPV vaccine is commonly known as cervical cancer vaccine. Currently, there are bivalent, quadrivalent and nine-valent cervical cancer vaccines on the market, which can prevent cervical cancer and precancerous lesions caused by different subtypes of human papillomavirus infection. HPV infection is particularly prone to infecting sexually active women, and the general population is more susceptible to HPV infection.

The scope of cervical cancer vaccination is all people who are susceptible to human papillomavirus infection, but it is best for women who have not started sexual life, as the actual effect of vaccination will be better. The currently recommended age groups are 16-26 years old. After the age of 45, the sexually active period has passed, and there is not much practical significance in getting the cervical cancer vaccine, so it is not recommended to get the vaccine. The vaccine itself is a protein, and vaccination may cause local pain, swelling, or fever.

In clinical medicine, there are certain age restrictions for cervical cancer vaccination. For example, the bivalent vaccine is for people aged 9-25 years old, the quadrivalent vaccine is for people aged 20-45 years old, and the nine-valent vaccine is for people aged 9-6 years old. The age at which cervical cancer vaccines are often required is mainly because as people age, their immune system may weaken and their ability to prevent cancer may also decline. Therefore, it does not mean that they cannot get the vaccine if they are over the age limit. They can still get the vaccine. After only getting the vaccine, the prevention effect can reach 90% within the required age. If you get the vaccine after the age, the prevention effect will be significantly reduced. If you are already over 45 years old, you should get the vaccine according to the agreed conditions.

It is not recommended to get the cervical cancer vaccine after the age of 45, because the response to the vaccine is relatively mild at an older age, the antigen produced is relatively low and will disappear quickly, and it is difficult to have a preventive effect against human papillomavirus infection. Therefore, the cervical cancer vaccine is basically ineffective. At this time, you can do regular cervical precancer screening, which is human papillomavirus testing and cervical liquid-based cytology testing. If both tests are normal, then follow up after 3-5 years. Human papillomavirus infection and cervical precancerous lesions can be treated in time, which is very effective in preventing the occurrence of cervical cancer.
